Heinrich d'Arrest discovered NGC 5008 on 18 May 1862 and noted a mag 10 star preceded by 1.1 seconds of time and 95" north.  There is nothing at his position and his object was not recovered by Bigourdan or Reinmuth.  Harold Corwin found that UGC 9073 = PGC 50629 is exactly 1 hour of RA east of d'Arrest's position and a mag 10.5 star precedes by 1.2 seconds, but it is just under 90" south (not north).  So NGC 5008 = UGC 9073.

8": faint, fairly large, pale, no resolution.

 

Likely associated with the tidal stream of the Sagittarius Dwarf Spheroidal Galaxy according to Law, Majewski (2010).

 

WH discovered NGC 5053 = H VI-7 = h1569 on 14 Mar 1784 (sweep 170) and recorded "an excessively faint cluster of stars intermixed with resolvable nebulosity 8 or 10' diameter.  The stars are so small that they cannot be seen without the greatest attention. 240 verified it beyond all doubts."  There is nothing at his position, but 2 min of RA west is this low surface brightness globular.

 

JH described "vL; eF; a cluster of stars 19 or 20m, with 4 or 5 = 15m; irreg R, vgvlbM; diam at least 8 or 10'.  A most curious and interesting object.  The stars are just discernable.  So faint, might easily be overlooked."  He also mentioned the RA of his father was "very much out" so he nearly lost the observation.  Dreyer used JH's position in the NGC.

24" (6/1/13): bright, large, elongated nearly 2:1 NNW-SSE, ~3.5'x2'.  Contains a large, bright core with a sharp, bright nearly stellar nucleus.  The overall outline and surface brightness is irregular with spiral structure evident.  A relatively thin, straight arm is attached on the west side of the core and shoots ~1.2' NNW, separating well from the central region. A second, lower contrast arm is attached at the NE side of the central region and hugs tightly along the eastern side of the core.  This arm was not resolved until it extended south of the central region.  A small, brighter knot (~10") is visible just north of the central region [~40" N of center]. A mag 13.5 star is just off the NE side, 1.3' from center and a mag 14 star lies NW of the western arm, 2.2' from center.  Forms a pair with MCG -03-34-040 2.6' NNW. The companion appeared faint, small, very elongated 7:2 N-S (major axis aligned with the nucleus of NGC 5054), 22"x6", even surface brightness.  The NGC 5044 group (7 NGCs) lies 20'-30' NW.

13" (5/26/84): very bright, elongated NNW-SSE, broad moderate concentration, stellar nucleus.  The southern edge is more sharply defined while the northern side is more diffuse and extensive.  A mag 8.5 star is off the NW edge.

 

Pierre MŽchain discovered M63 = NGC 5055 = h1570 on 14 Jun 1779.  On 18 Mar 1787 (sweep 717), WH recorded "E from np to sf., 5 or 6' long and near 4' broad, a bright nucleus, very brilliant."  On 9 Apr 1787 (sweep 725) he logged "vB, 9 or 10' long, considerably broad, the brightness confined to a small place."  JH logged "B; pmE; vsmbM, almost to a *, pos 30” np to sf.  The sf end more diffused.  Has a bright star np and a double star following."

 

On 9 Mar 1850, LdR (or observing assistant George Johnstone Stoney) noted M63 was "another fine and bright spiral."  Later observations couldn't confirm the spirality, though the galaxy is included in the list of "Spiral or curvilinear" nebulae in LdR's 1850 PT paper.

The only galaxy nearby that matches this description is NGC 5072, which has a 14th magnitude star superimposed on the south end, giving the initial impression of a faint double star. So, based on Swift's description, NGC 5070 = NGC 5072.  This galaxy was discovered earlier by d'Arrest on 26 Apr 1867 and placed accurately.

JH discovered NGC 5086 = h3486 on 7 Apr 1837 within a group including NGC 5082, NGC 5090 and NGC 5091.  He described NGC 5086 as "eF, R, 15", the 2nd of a group of 4" and placed it 10 sec of RA west and 50" south of NGC 5090, the brightest in the group.  There is no galaxy at this offset, though very close to his position is a pair of mag 14-15 stars at 17" separation that Harold Corwin identifies as NGC 5086.

 

The RNGC misidentifies ESO 270-003 as NGC 5086.  This galaxy is located 3.4' due south of NGC 5090.  This error was noted in my RNGC Corrections #5.   ESO likely misidentifies ESO 270-001 as NGC 5086.  This galaxy is 12 sec of time west of NGC 5090 and 2' south.

See observing notes for NGC 5100.  The equivalence with NGC 5100 is uncertain and Reinmuth and Carlson identify NGC 5106 with a star.

 

WH discovered NGC 5106 = H II-22 on 23 Jan 1784 (sweep 108) and recorded a "a vS and F neb, sp 59 Vir.  Its A.R. is about 13h 06 1/4m [No polar distance recorded].  While I looked into the finder to determine its situation I lost it, but shall endeavor to find it another night."  Dreyer noted in "Scientific Papers of William Herschel" there is no nebula in WH's place and this number probably refers to NGC 5100 (found by Marth), which is 35 sec preceding and 30' north of the assumed place of II-22."  In his NGC correction list, Dreyer repeats "II.22 must be = 5100."   Harold Corwin notes there are inconsistencies with this identification, so the identity NGC 5106 = NGC 5100 is "provisional".  See his notes for more.

 

Karl Reinmuth probably looked for NGC 5106 at the NGC position and reported "=*14.0; 13 14.3 +09 15 (1860) neb susp."  This was repeated by Dorothy Carlson and by the RNGC.

See observing notes for NGC 5111.  As far as RNGC 5111 = PGC 46719, it appeared very faint, small, slightly elongated E-W, 25" diameter, low even surface brightness.  A mag 13 star lies 1' NE.  Located 8' SW of NGC 5111 and a similar distance north of mag 7.8 SAO 157895.  The NGC identification is uncertain as Swift's position was poor and NGC 5110 may be a duplicate observation of NGC 5111.

 

Lewis Swift found NGC 5110 = Sw III-71 on 3 Jun 1886 and recorded "eF, pS, R, in line with 2 pB stars".  His position is 6 sec of RA west and 2.4' south of NGC 5111 (discovered by WH).  This galaxy is collinear with two mag 12 and 13.5 stars to the northwest, matching Swift's description.

 

RNGC and PGC misidentify  PGC 46719 as NGC 51110.  This galaxy is 13 sec of RA west and 3.5' south of Swift's position.  More importantly, it is not in line with "2 pB stars" as Swift noted.  But Malcolm Thomson feels this galaxy is still a reasonable match.

 

Harold Corwin equates NGC 5110 with NGC 5111 as this galaxy is in a line with two mag 12-13 stars to the northwest.  In this case, Swift's position is 12 tsec E and 4' too far south.  Based on the description, NGC 5111 is a better match, though I'm surprised Swift would call this galaxy "eF" as the magnitude is V = 11.7.

48" (4/13/10): at 330x there was a fascinating amount of structure in the wide, equatorial dark lane that bisects the galaxy.  The dust lane varied in width with fine structure along its ragged, crenated edge.  The interior of the dust lane also varied in brightness with a bright patch close to the center, just following a bright, mag 12 star near the south edge of the lane.  This patch is elongated with some structure and may be the visible portion of the obscured core.  Clouds interrupted this brief observation.

 

24" (4/11/08 - Magellan Observatory, Australia): I didn't take detailed notes with the 24", but the appearance was mesmerizing at 200x.  The equatorial dust lane was more full of contrast and exhibited finer texture and scalloped detail at the edges than I've observed previously in smaller scopes from Australia.

 

20" (6/29/02 - Bargo, Australia): at 230x, Cen A nearly fills the 15' field.  The 15'x1' dark rift is fascinating with a scalloped, wavy edge and a thin streak is easily visible near the center within the rift.  This was easily the most detailed view I've ever had of Centaurus A.

 

12" (6/29/02 - Bargo, Australia): at 186x, Centaurus A appeared very bright with a large, prominent dust lane cutting a dark swath through the center from NW-SE.  The SW hemisphere is a bit larger and more prominent and contains a bright star.  There is a mag 12 star within the dust lane (west of center) with two very faint stars at both NW and SW borders of the lane.  Some faint haze is superimposed near the center of the dark rift, following the star superimposed on the lane.

 

17.5" (3/12/88): bright, large, very large prominent dust lane oriented NW-SE.  The SW hemisphere is larger and brighter.  A star is superimposed at the south edge of the dust lane (west of center) and a bright star is superimposed on the SW hemisphere (south of center).

 

13" (4/24/82): wide dust lane bisects galaxy with the southwest hemisphere dominating in terms of size and brightness.  A very faint star is at the SW edge of the dust lane.

 

James Dunlop discovered NGC 5128 = D 482 = Centaurus A = h3501 on 29 Apr 1826 . Cen A was discovered on the second night he started recording deep sky objects with his 9-inch f/12 speculum reflector -- NGC 4945 was found on the same night.  He reported "A very singular double nebula, about 2.5' long and 1' broad, a little unequal: there is a pretty bright small star in the south extremity of the southernmost of the two, resembling a bright nucleus: the northern and rather smaller nebula is faint in the middle, and has the appearance of a condensation of the nebulous matter near each extremity.  These two nebulae are completely distinct from each other, and no connection of the nebulous matters between them.  There is a very minute star in the dark space between the preceding extremities of the nebula; they are extended in the parallel of the equator nearly."  His sketch (Fig 20) shows two parallel bands with a star between at one end.

 

JH made several observations: on 1 Jun 1834 he logged "A most wonderful object; a nebula vB; vL; lE; vgmbM; of an elliptic figure, cut away in the middle by a perfectly definite straight cut 40" broad; pos = 120.3 ; dimensions of the nebula 5' by 4'. The internal edges have a gleaming light like the moonlight touching the outline in a transparency." On his next sweep he describing "[Two nebulae, or two portions of one separated by a division or cut.] The cut is broad and sharp. The two nebulae are very nearly alike. Perhaps the slit is larger towards the N.p. end, where there is a star between them. There is certainly a very feeble trace of nebula, an island as it were, running from this star between the sides of the slit." (Sketch on plate IV, figure 2).

 

In 1922, Hubble included NGC 5128 in a list of diffuse nebula with emission spectra, along with M42, the Veil, M8, M16, M17, etc.  It wasn't until 1947 that Harlow Shapley classified it as an irregular galaxy.

18" (7/11/05 - Magellan Observatory, Australia): at 228x, roughly 100 stars are visible in a 12' region, though the group is not detached well enough at this power to recognize as a cluster.  At 76x (27 Panoptic), barely stands out as a distinct group as it resides in a very rich star field. Includes over two dozen mag stars roughly 11th magnitude. Two mag 8.5/9.5 stars (HD 116721 and 116689) to the NW by 6' and 9' are collinear with the center of the cluster.

 

James Dunlop discovered NGC 5138 = D 312 = h3503 on 26 May 1826 with his 9-inch f/12 reflector at Parramatta.  He recorded "a pretty large faint nebula, about 5' diameter, irregular branched figure, resolvable, with considerably compression of the stars towards the central point. This precedes a star of the 7th mag, and a group of small stars follows, about 10' north of the nebula."  His catalogued position was 14' too far south but Glen Cozens found a transcription error from the original position, which was 6' too far north.

 

JH tentatively identified his h3503 as Dunlop 312.  He observed the cluster twice; on 3 May 1835 he recorded "General middle of cluster VIII. class. pB; L; irr; scattered, 30 or 40 stars 11..12 mag and many smaller; pretty well insulated, though on a ground rich in very small stars." On a second sweep he logged "Cluster VII class; rather a fine cluster; rich, but loose and straggling. Fills field. Stars 11 and 12th mag."

NGC 5139 = Omega Centauri Cluster = ESO 270-SC11

13 26 45.8 -47 28 36

V = 3.7;  Size 36.3'

 

24" (4/11/08 - Magellan Observatory, Australia): at 200x in excellent seeing, the view was absolutely stunning as the field was packed with thousands of pinpoint stars to the edge of the 30' field!  I noted the circular ring of stars near the center mentioned previously, but the large number of brighter, densely packed stars in the core and halo, superimposed on an incredibly rich mat of fainter stars was the real show.  The cluster is only broadly concentrated with very large, brighter core ~10' in diameter and the star density thins out very slowly all the way to 35' diameter.

 

20" (7/08/02 - Magellan Observatory, Australia): at 208x with a 24' field, the cluster overfilled the field with edge to edge stars mag 11.5 and fainter and was a breathtaking sight.  Broadly concentrated with large, brighter core of at least 10' in diameter.  The core is extremely densely packed with layers of stars.  The elongated halo gradually thins but has no definite border out to 30'!  This is the largest and brightest globular in the sky (V = 3.7) and an obvious naked-eye blur, but lacks the strong central condensation of NGC 104 = 47 Tucana.

 

18" (7/10/05 - Magellan Observatory, Australia): although I've mentioned this feature on previous observations I was surprised to be drawn to a 1' circular ring of stars just north of the geometric center which is mainly filled with unresolved glow and appears like a darker "hole" near the center.  A second smaller and less distinct 30" ring of stars and darker center is adjacent to the south with the two rings externally tangent in the middle.

 

After the observation I checked John Herschel's description and found these comments on the star rings in the center: "One of these rings, 1.5' in diameter, is so marked as to give the appearance of a comparative darkness like a hole in the centre.  My attendant (J.S.) called up, who saw the hole and darkness, and described it as I have done above. On further attention the hole is double, or an oval space crossed by a bridge of stars. Position of axis = 150."

 

13.1" (2/20/04 - Costa Rica): at 105x in excellent seeing, the view was absolutely breathtaking with wall-to-wall pinpoint stars in the 37' field!  There was a clear 3-dimensional effect with the 11.5-12.5 magnitude stars seemingly floating over a dense mat of fainter stars with the streamers in the halo reaching the edges of the field. I don't recall a more impressive view in the 12" from Australia, where the cluster was higher in the sky.

 

13.1" (2/19/04 - Costa Rica): In very good seeing early in the morning of the 20th, Omega Cen was a mesmerizing sea of a couple of thousand stars at 200x.  I set Omega just outside the field and let it drift through the field a few times.  The outer halo was an amazingly dense swarm of 12-13th magnitude stars over a background of fainter pinpoints of lights spilling over the edge of the field.  Very broadly concentrated to a large, brighter center although there is no well-defined core.

 

12" (6/29/02 - Bargo, Australia): this was the first object I viewed at Bargo with Les Dalrymple's 12" and was not disappointed.  At 140x, it filled 2/3 of the field (over 25') and resolved into perhaps a few thousand stars down to the center.  The cluster seemed almost 3-dimensional with a lattice of brighter mag 12 stars superimposed on a dense background layer of mag 13-14 stars.  The density was generally uniformly high in the elongated halo except near the edge although the core shows more non-uniformity with a couple of darker patches.

 

17.5" (3/12/88): very large, very bright, fantastic at 220x with several hundred stars resolved in excellent seeing from east of Mt. Hamilton.  Very faintly visible to the naked eye in good conditions near the horizon from northern California. 

 

13.1" (3/24/84): large, mottled disc covered with faint stars, well resolved outer halo.  Similar view but even better resolution on 2/23/85.

 

8" (7/13/91 - Southern Baja): very bright, very large, very broadly concentrated, about 25' diameter, over 100 stars resolved mag 12-13, many in curving streams over the entire disc.  Visible naked-eye.

 

Edmond Halley discovered Omega Centauri = NGC 5139 = Lac I-5 = D 440 = h3504 telescopically by 1677 from St Helena.  Nicolas-Louis de Lacaille reported "Naked eye, a 3rd mag star [10 Cen] in a fog. Telescope, [Half-an-inch aperture, 8x magnification] like a big diffuse comet."  James Dunlop resolved the cluster on 7 May 1826 with his 9-inch speculum reflector and described "a beautiful large bright round nebula, about 10' or 12' diameter, easily resolvable to the very centre; it is a beautiful globe of stars very gradually and moderately compressed to the centre; the stars are rather scattered preceding and following, and the greatest condensation is rather north of the centre: the stars are of slightly mixed mags, of a white colour. This is the largest bright nebula in the southern hemisphere." Of course, the cluster is an easy naked-eye object and Ptolemy included it in the Almagest and Johann Bayer catalogued it as a 4th magnitude star (Omega) in the early 17th century.

 

On 20 Apr 1836 JH recorded "Globular; Omega Centauri; diameter full 20'. It much more than fills the field. When the centre is on the edge of the field, the outer stars extend fully half a radius beyond the middle of it. The stars are singularly equal, and distributed with the most exact equality, the condensation being that of a sphere equally filled. - Looking attentively, I retract what is said about the equal scattering and equal sizes of the stars. There are two sizes 12th mag and 13th mag, without greater or less, and the larger stars form rings like lace-work on it. One of these rings, 1.5' in diameter, is so marked as to give the appearance of a comparative darkness like a hole in the centre. There must be thousands of stars. To the naked eye it appears as a star of 5th mag or 5.4, rather hazy. There is a * 9m on the S.p. border of it, about 4' or 5' south of centre, and several 8th mag are scattered far away.  My attendant (J.S.) called up, who saw the hole and darkness, and described it as I have done above.  On further attention the hole is double, or an oval space crossed by a bridge of stars.  Position of axis = 150”.  Altogether this object is truly astonishing."

18" (7/11/05 - Magellan Observatory, Australia): gorgeous low power Milky Way field at 76x, but it was difficult to identify the cluster not having a finder chart.  Initially I was drawn to a striking asterism in the field consisting of a distinctive group of four stars forming a rough 8'x3' parallelogram with brightest member mag 7.8 HD 117356, but the enclosed stars were no richer than the surrounding field and it looked like an asterism.  Then I noticed that 12' S of the mag 7.8 star was an eye-catching double star = HJ 4591 (10.2/10.4) at 7" surrounded by a few faint stars over unresolved haze.  Increasing the magnification to 228x, this rich knot resolved into three dozen mag 14 and fainter stars in a 2'x1.5' roundish cluster with the double star on the following side and this was clearly NGC 5138.

George Hough discovered NGC 5171 on 5 May 1883 with the 18.5-inch refractor the Dearborn Observatory and recorded "Double. Nebula, round, condensed."  The second object actually refers to a star at the northwest edge.  Wilhelm Tempel found NGC 5171 just 6 days later and reported it in list VIII-2.  Ernst Hartwig found it again on 29 Jun 1883 with the 18-inch Merz refractor at the Strasbourg Observatory (AN 2688).  These three independent discoveries were made while searching for d'Arrest's comet.  While searching for the comet, Hartwig also discovered the close pair NGC 5176 and 5177.

Interestingly, the first observation by JH also describes a double system (probably following his father's lead): "vF; two close together, or one E nearly in meri.  A star 11m N."  His second observation simply states "eF, E, involves a star at the S end."  Dreyer's observation at Birr Castle on 4 Apr 1877 mentions "found only one neb, vF, vS, stellar no other neb found."

 

Lewis Swift independently found the galaxy again on 19 Mar 1887 and recorded it in list VI-58, but his position was 1 tmin too far west.  Dreyer, assuming it was new, catalogued it as NGC 5162.  So, NGC 5174 = NGC 5162.

24" (4/11/08 - Magellan Observatory, Australia): this was the final object of 78 that I logged on 4/11/08 and the perfect end to a great evening with the 24".  At 200x using a UHC this amazing planetary displayed an extremely complex morphology.  Through the center is a bright, high surface brightness "bar" elongated WSW-ENE and ~1.5'x0.4' in size.  This central feature has an uneven surface brightness with a mottled texture. A mag 12 star is superimposed just north of the west-southwest end and the fainter central star is just south of the bar.  A close double star (~3.5") is superimposed just south of the west-southwest end.  At this end a spiral extension hooks around counterclockwise to the north and passes through a faint star and ends at a very faint small knot just north of the superimposed star.  A bright 10" knot is just south of the east-northeast end of the central "bar".  Attached to this knot is another extension that sweeps towards the southwest, ending less than 1' S of center.  About 50" E of the bright knot is another 10" knot that appears detached.  A mag 12 star is ~50" SW of this knot, just outside the halo of the planetary.  All of the brighter features are within a much fainter oval envelope, ~2.5'x2.0'.

 

18" (7/6/05 - Magellan Observatory, Australia): the "Spiral Planetary" is certainly one of the most remarkably structured planetaries and would be famous if located in the northern hemisphere.  At 128x using a UHC filter, a high surface brightness "bar" at least 1' in length, elongated SW-NE forms the main body of the planetary.  The bar is slightly curved and has an irregular surface brightness.  On the NE end is a prominent bright knot, roughly 6" in size.  Nebulosity hooks below this knot, extending below the bar.  Above the southwest end of the bar is the brightest superimposed star and a hook of nebulosity sweeps up to the northwest, wrapping above this star.  The entire structure is encased in a much fainter oval envelope.  A total of five stars are superimposed including a very close double that is just south of the southwest end of the bar and the 14th magnitude central star situated southeast of the center of the bar.

 

12" (6/29/02 - Bargo, Australia): this is a bright, strange-looking PN with a complex bar structure dubbed the "Spiral Planetary".  At 140x and UHC filter, it resembles a small barred spiral galaxy with prominent bar extending SW-NE with curved tips, ~1' in length embedded within a fainter, slightly elongated halo of ~2'x1.5'.  A few stars are superimposed.  At 186x, the "bar" is irregular and knotty with a bright knot at one end.  A mag 11 star is at the SW end with a couple of faint stars on the opposite end. The faint 14th magnitude central star is just south of the bar.  Set in a rich star field in the NE corner of Musca 6' NNW of mag 7.2 SAO 252366.  This is a fascinating sight!

 

James Dunlop discovered NGC 5189 = D 252 = h3514 on 1 Jul 1826 using his homemade 9-inch f/12 speculum reflector. This is one of three or four southern planetaries that he identified.  He recorded "very faint nebula, about 25" diameter. It is very near a star of the 8th mag, and near the north following extremity of a crescent of very small stars." His position is off by 15', but the description is adequate to identify.

 

JH recorded "A very strange object.  A nebula of oval fig, but having a central and brighter axis somewhat curved, and terminating in two masses brighter than the rest; diam about 90" or 100".  It involves 3 stars, one of which with 320 is double.  The principal star is 10m, the others eS; a multitude of other stars in field."  Sketched on Plate VI, figure 1.

 

Williamina Fleming found it again in 1901 on a Harvard objective prism plate taken at the Arequipa station and reported it as new in Harvard Circular 60.  Dreyer missed the equivalence in position with NGC 5189 and recatalogued this planetary as IC 4274 =  Fleming 96.  The North Polar Distance in the IC has a typo of 115”.  It should read 155” based on the original position, matching NGC 5189.

17.5" (6/2/00): moderately bright and large, round, 1.2' diameter, fairly sharply concentrated with a small bright core.  A mag 12.5 star lies 1.2' N of center.  Located 4.6' W of mag 8.2 SAO 204565.  Forms a close pair with a faint edge-on (NGC 5193A) at the west edge [57" between centers].  The companion was extremely faint, very small, elongated, ~0.4'x0.2', required averted to momentarily glimpse.  NGC 5193 and 5193A are members of LGG 353 in the foreground of AGC 3560.

48" (5/12/12 and 4/7/13): during these views with Lowrey's 48" I focused on some of the brighter knots in the spiral arms, which have a very high contrast with the large, dusty, darker regions between the arms.  The "southern" arm nearly merges with the core on the northeast side.  As this arm unwinds clockwise to the west, two close very small, fairly bright knots ([CCM69] #77 in Carranza, Crilon and Monnet's "Kinematic Study of Ionized Hydrogen in M51" in A&A, 1, 479) are visible 1.6' W of center, just SE of a star.  A small bright knot (#71) is further out on this arm, 2.3' SW of center. The section of the arm between these knots is quite bright and mottled.  The southern arm then continues to swing around on the east side and heads north, with a lower surface brightness bridge to NGC 5195.

 

The "northern" arm begins on the south or southwest side of the core, and a series of small knots (#60/67) are along the inner south side, roughly 1' from center.  As the arm unwinds on the east side of the core, a large bright knot (#52) resides ~1.4' ESE of center.  The arm is quite bright in a large, clumpy region (#27/29) as it heads north in the direction of NGC 5195.  At the closest point to NGC 5195 are 4 very small knots; the brightest is #10, 2.6' NNE of center.  Very close southwest is #8 and just northwest is #5.  This arm then has a sharp bend and shoots west on the north side and includes a moderately large, brighter patch (#90/91) 2' NNW of center. The arm fades somewhat as it unwinds further along the western edge of the halo.

 

48" (4/2/11): during this observation I focused on the attached companion NGC 5195. The entire connecting arm was always a prominent direct vision feature of the pair with variations in brightness and width along its length.  The arm brightened as it connected to NGC 5195.  The slightly oval core was extremely bright but nevertheless a very bright stellar nucleus punctuated the center.  The spiral arms had an extremely high contrast and appeared etched in the eyepiece like a photograph with a great deal of knotty structure.  The outer arm that sweeps clockwise to the north and then around the west side extended much further south (~5' from center) than I had ever previously seen and separated quite a bit from the main spiral.  Sprays of nebulosity looped off of NGC 5195 to the north (see notes).

 

17.5" (3/28/87): stunning spiral structure, connecting arm visible with direct vision.  First observation with 17.5" on 23 Mar 1985.

 

13.1" (4/24/82): very bright, very large, bright nucleus.  Two winding spiral arms are obvious with a dark gap between the arms on the west side.  The connecting arm to NGC 5195 is definite although near my visual threshold.  There is a sharp bend in the outer arm at the south end of the galaxy. After this point, the arm trails faintly north to NGC 5195 located 4.6' from center.

 

8": bright, large, hint of spiral arms.

 

Charles Messier discovered M51 = NGC 5194 = h1622 on 13 Oct 1773 with a 3.5-inch refractor.  Johann Bode made an independent discovery on 5 Jan 1774 along with the first drawing using his 3-inch refractor.  In William Herschel's earliest observation (20 Sep 1783) using a 12-inch, he noted "most difficult to resolve; yet I no longer doubt."  Viewing with his 18.7-inch on 29 Apr 1788, he described "Two, the most south vB, L, surrounded with a beautiful glory of milky nebulosity with here and there small interruptions that seemed to show the glory at a distance."  On 12 May 1787 he recorded "B, a very uncommon object.  Nebulosity in the center, with a nucleus surrounded by detached nebulosity in the form of a circle; of unequal brightness in 3 or 4 places; forming altogether a most curious object."  He apparently never observed M51 with his 48-inch reflector (40-foot focal length).  JH described M51 as "A very bright round nucleus surrounded at a distance by a nebulous ring" and as a "double ring, or rather one-and-half rings rather like an armillary sphere."

 

M51 was the first galaxy in which spiral structure was clearly seen.  The discovery was made by Lord Rosse (William Parsons) using his newly completed 72-inch Leviathan in the spring of 1845 (replacing the earlier 36-inch scope).  No observing logs were kept of the earliest observations, so the exact date in unknown, but spirality was not reported by Romney Robinson (director of the Armagh Observatory) and James South (double star observer) during their observation on 5-6 March 1845, which focused on resolvability.  In early April 1845 (possibly the 6th), William Parsons observed alone and "discovered" the spiral structure, producing a stunning sketch that was circulated at the British Association for the Advancement of Science in Cambridge in June 1845.  By 1850, M51 had been observed at least 28 times and a second, more dynamic sketch implying motion, was published in LdR's 1850 "Observations of the Nebulae" (plate XXXV, figure 1).  Isaac Roberts produced the first photograph confirming the spiral structure on 29 Apr 1889.

 

As far as the origin of the nickname "Whirlpool Galaxy", Ormsby Mitchel's 1847 column in Sidereal Messenger, Vol. 2, No. 4 announced "Lord Rosse's Whirlpool Nebula" and included a copy of his sketch.   The following year Romney Robinson described spiral nebulae "... resemblance to bodies floating on a whirlpool is, of course, likely to set imagination at workÉÓ

48" (4/2/11): I was shocked by the detail and structure visible in the companion to M51 at 375x.  The main 2' portion of the galaxy has a striking asymmetric appearance with an extremely high surface brightness "bar" perhaps 2'x0.8' elongated N-S with a sharp light cutoff on the east side.  Attached on the east side of a bar is semi-circular "loop" extending about a 1' E and connected at the north and south end of the bar. The western loop portion of NGC 5195 was slightly brighter where it connected at the north and south end and the interior of this loop is irregularly darker.  On first glance there appeared to be an obvious short "arm" connected to the northeast end of NGC 5195 heading south, but then I realized this was the long connecting arm from M51 that brightened in the last 1' where it attaches to NGC 5195.  The entire connecting arm was always a prominent direct vision feature of the pair.  The center of the bar was sharply concentrated with an extremely bright, quasi-stellar nucleus.

 

At least three distinct plumes of nebulosity extended from NGC 5195 to the north. A broad wing of hazy nebulosity begins near the NE end (at the end of the connecting arm) and sweeps 2' to the north in a gentle curve.  A second shorter plume extends directly north from the north end of NGC 5195.  Finally a mass of very low surface brightness nebulosity spreads to the west from the southwest end of the galaxy and clearly sweeps towards the north for ~2.5'.

 

13.1": bright, fairly small, very irregular appearance.  Forms a double system 4.6' N of M51 and connected on the east side by a faint spiral arm of M51 which trails north on the east side to NGC 5195.  The following side is sharply cut-off due to dust and appears as a half disc.

 

Pierre MŽchain discovered the northern component of M51 or NGC 5195 = H I-186 = h1623 on 20 Mar 1781 and commented "saw this nebula; effectively it is double.  The center of each is brilliant and clear; distinct and the light of each touches each other."  Messier mentioned this companion to M51 in his 1784 version of the catalogue in Connaissance de Temps, though it never received recognition as a separate Messier object.  WH found it on 12 May 1787 (sweep 734) and recorded "B, S, R, vgbM.  Just north of the former [M51]."  JH reported "B; R: vsbM to a star.  This nebula is the companion of M51 and is figured with it."

 

LdR and assistants described NGC 5195 as probably a spiral on several observations and other details were noted.  On 17 Mar 1855: "I have no doubt of a spiral arrangement of the smaller Nucl."  On 16 Apr 1855: "The 2nd Nucl seems to be the proper prolongation of the spiral arm with which it is connected."  On 18 Apr 1860: "I still think the small Nucl is shaped like an "S". On 12 Apr 1872: "The edge of the 2nd convol. is very nearly rectilinear on the south side."

JH discovered NGC 5212 = h1631 on 24 Apr 1830 and simply note "eF".  There is nothing at his position, which is east of NGC 5208 and 5209.

 

Karl Reinmuth identified CGCG 045-014 as NGC 5212.  This galaxy is 27 sec of RA west of JH's position and matches in declination.  RNGC identifies CGCG 045-008 as NGC 5212.  This galaxy is situated 1.7' southeast of NGC 5208 and is 50 seconds of RA west of JH's position.  Harold Corwin favors a 20" pair of 15th magnitude stars just 1' north of JH's position.  I don't think any of these identifications are compelling and the identification should perhaps be left as "lost".

WH discovered NGC 5216 = H II-841 = h1635, along with II-842 = NGC 5218, on 19 Mar 1790 (sweep 953) and logged "pB, S, iF." CH's reduced position is 2' northeast of UGC 8528.  JH measured an accurate position for h1635, but thought it was a new object, as he applied II-841 to NGC 5218.  The identifications were corrected in GC and NGC, but still the MCG has NGC 5216 and 5218 reversed.

 

The nickname "Keenan's System" derives from a 1935 paper "An Unusual Pair of Nebulae: NGC 5216 and 5218" (in 1935ApJ....81..355K).  Keenan announced that based on a Yerkes 24-inch plate "these two apparently well-separated galaxies are connected by a faint but definite band of nebulosity... The case is striking, among the small number of pairs known to be physically connected, because of the considerable separation of the two objects in proportion to their size."  The paper included a photograph of the system.  Zwicky used the name "Keenan's System in his 1956 paper "Multiple Galaxies" on interacting galaxies (http://articles.adsabs.harvard.edu/full/1956ErNW...29..344Z).  The filament connection the galaxy stretches 22,000 light years long.

ESO 220-023 (similar redshift) lies 5.6' NNW.  This fairly faint edge-on extends 4:1 SW-NE, 0.6'x0.15', slight bulge at center, tapers at ends.  Collinear with two mag 12.2 and 10.5 stars situated 1.2' SE and 1.9' SE.  It also forms the eastern vertex of a triangle with two mag 10.5 stars 2.5' WNW and 3' SW.  Two more ESO edge-ons (again part of the same group) lies 10' SW of NGC 5234 but I didn't look for these.

 

JH discovered NGC 5234 = h3522 on 6 Jul 1834 and recorded "eeF; lE; 30".  Requires a newly polished mirror, and a night such as this is to be seen."  His position is accurate.

V = 7.5;  Size 12.9'x11.5';  Surf Br = 12.8

 

48" (4/7/13): During this observation of M83, I focused on the HII regions that light up portions of the remarkable spiral arms that emanate from the 3'x1' central bar.  The bar is sharply concentrated with a small, intensely bright, 1' round core.  At the northeast end of the bar a high contrast arm begins to sweep counterclockwise along the east side, ending up directly south of the core.  Several knotty clumps were visible in the region where the arm is attached.  First, at the northeast end of the central bar [1.2' NE of center] is NGC 5236:[dPD83] 42, a 10" HII knot.  This designation is from a 1983 paper by de Vaucouleurs, Pence and Davoust that includes a map of the 60 brightest HII regions.  Close east of this knot is #46, a 20"x10" elongated patch, situated where the arm begins to unfurl to the south [1.7' NE of center].  HII region #54 is another 12" knot a bit further southeast [0.6'] along the arm [1.9' ENE of center].

 

On the opposite southwest end of the bar a prominent second arm emerges and spirals out counterclockwise along the west side of the galaxy heading north and then spreading out as it curves east.  The arm dims noticeably on the northeast side of the halo near a mag 13 star and has a low surface brightness as it continues south in the outer halo, heading towards h 4599, an 8" pair of mag 8.2/10.7 stars.  Several knots are visible in this arm.  As the arm emerges at the southwest end is #22 and #18, a small 10" knot [1.8' SW of center].  Close north is an elongated clump [2.0' WSW of center], ~25"x10", containing #13 and #15.  Another elongated patch, 30"x10", containing #12 and #16, is 1' further north along the arm [1.9' WNW of center].  Additional HII regions were visible at the northern side of the arm; #39 and #43 are a close pair of small knots ~2.5' NNE of center.  Further east along the arm [3.3' NE of center] is #56, another elongated patch, 20"x10".

 

A third, wider and more diffuse arm begins on the south side of the bar.  It extends below the brighter arm on the west side, and sweeps more gradually, forming an outer western arm. This arm passes just north of a mag 12 star and ends about 4' W of center at a brighter, elongated patch that includes #2 and #3, as well as a mag 15 star.

 

48" (5/15/12): jaw-dropping view of M83, with the galaxy filling about 2/3 of the 375x field.  I didn't take detail notes as we were looking for a recently discovered ultraluminous X-ray source (ULX), in which a companion star is orbiting a neutron star or black hole.  We found a stellar or quasi-stellar object at the north edge of the central core, but this was likely a compact HII region (the ULX is ~1' E of the nucleus).

 

24" (4/11/08 - Magellan Observatory, Australia): M83 resembled the photographic appearance in the 24" at 200x.  The bright "bar" was elongated SW-NE and roughly 3'x1' in size with a well-defined bright, round core, 1' in diameter.  The first prominent arm is attached at the northeast end of the bar and sweeps south (counter-clockwise) on the east side of the core, wrapping around the southeast side and spreading out a bit as it terminates to the south of the core (~3' from the center).  This arm has a high contrast along its outer edge and a couple of faint stars or HII knots are visible near where it attaches to the bar.  On the southwest end of the bar a second prominent inner arm emerges and abruptly wraps counter-clockwise around the galaxy on the west side as it heads north.  This arm continues to wrap around the north side before spreading out on the northeast side and merging into the outer halo ~3.5' from center on the northeast edge of the halo. A third, more ill-defined arm, also emerges from the core on the south but sweeps more gently to the west (instead of heading north) on the outside of the second arm.  It spreads out and fades into the general glow about 3.5' SW of center near a superimposed mag 12 star.  Offshoots of the main arms are difficult to trace and contribute to the general background glow of the halo.

 

18" (7/11/05 - Magellan Observatory, Australia): in addition to the complex 3-armed spiral structure I was surprised to see a fairly obvious linear bar that extended through the small, intense core in SW-NE orientation.  The fairly tightly wound spiral arm that wraps from the east side of the core around the south side in a counter-clockwise orientation clearly emerges from the NE end of this bar.  The spiral arms that begin on the south and west side more vaguely emerge from the general glow near the SW end of the bar.

 

13.1" (2/20/04 - Costa Rica): beautiful view with easy spiral structure in excellent seeing conditions.  The main central portion of the galaxy appears to be in motion, due to the embedded spiral structure and darker ribbons add to this impression.  The three principal arms extending from the galaxy were well seen although they are fairly tightly wound to the main body.

 

13.1" (2/19/04 - Costa Rica): this impressive galaxy was viewed carefully at both 105x and 166x.  The overall size including the spiral arms are ~8'x6'.  The halo is broadly concentrated then rises sharply to an intense 25" core that increases to the center.  Complex spiral structure is quite obvious.  A spiral arm is attached on the east side of the core and wraps around the south side of the galaxy in a counter-clockwise direction.  A second arm is attached at the south side of the core and winds to the west a bit on the south side.  Finally, an arm is attached on the west side and shoots north before gently bending east along the north side of the outer halo.

 

12" (6/29/02 - Bargo, Australia): this was my best view to date of M83 with a beautiful spiral structure clearly evident and multiple knotty arms.  Well concentrated with a prominent core and very small nucleus.  A very long, spiral arm is attached on the west side of the central core or bar but quickly bends to the north, becoming more spread out and diffuse.  It continues to wind along the entire east side of the halo and fades out near a close double star, which is the middle of three collinear stars to the SE of the galaxy.  Two other principal arms are visible - one is attached on the following end of the core and heads south, wrapping clockwise around the core towards the west.  A third arm emerges from the core on the west side and winds clockwise towards the north.  Offshoots of the main arms are difficult to trace and contribute to the general background glow of the halo.

 

17.5" (5/10/86) : brighter arm or arc visible north of the core.

 

13.1" (3/24/84): very bright, large, very bright core, brighter along the central "bar".  The shape of the spiral arms and central bar form the Greek letter "Theta" surrounded by a faint halo.

 

8": very bright, bright core, elongated, impressive.

 

Nicolas-Louis de Lacaille discovered M83 = NGC 5236 = Lac I-6 = D 628 = h3523 in 1751-1752 with a 1/2" telescope at 8x during his expedition to the Cape of Good Hope.  He simply described a "small, shapeless" nebula.  It is also the only galaxy in Lacaille's list.  Charles Messier was barely able to view it from Paris, noting "It appears as a faint, even light, but is difficult to see with the telescope that the slightest illumination of the micrometer's crosshairs causes it to disappear.  It requires considerable concentration to see at all."

 

WH made two observations of M83:  On 15 Mar 1787 (sweep 711) he logged "vB, a bright resolvable nucleus in the middle with F branches about 5' or 6' long, E sp-nf."  On 5 May 1793 he logged "vB, a SBN with very extensive and vF nebulosity; it more than fills the field, it seems to be rather stronger from sp to nf. It may be ranked among the nebulous stars."

 

James Dunlop observed M83 on 29 Apr 1826 and recorded "185 Centauri is a very beautiful round nebula, with an exceedingly bright well-defined disk or nucleus, about 7 or 8 arcseconds diameter, surrounded by a luminous atmosphere or chevelure, about 6' diameter. The nebulous matter is rather a little brighter towards the edge of the planetary disk, but very slightly so. I can see several extremely minute points or stars in the chevelure, but I do not consider them as indications of its being resolvable, although I have no doubt it is composed of stars."  His published position is off by some 12+ tmin in RA, but Glen Cozens found a copying error of exactly 13 tmin from his original position.

 

JH's first observation from the Cape of Good Hope on 5 May 1834 reads "vB, vL, sbM to a centre equal to a star 9th mag, diam 8", of a resolvable character like a globular cluster, surrounded by an immensely large, extremely dilute almost equable light 7' or 8' diameter, somewhat oval, and passing with excessive suddenness into the central light."

 

William Lassell first recognized the spiral structure using his 48-inch fork-mounted reflector on Malta in May 1862 and sketched M83 as an elegant three-branched spiral. (Plate VII, Fig. 28, in Memoirs of the Royal Astronomical Society, Vol 36).

This galaxy, along with Fourcade-Figueroa galaxy = ESO 270-017, may have formed from a close interaction between Centaurus A and a spiral galaxy.  A 1992 paper suggest it was ejected as a non-rotating shred of dusty, gas-rich disc material that appears as a blue irregular/starburst dwarf galaxy.

JH discovered NGC 5242 = h1647 on 10 Apr 1828 and recorded "eF, vL, fills the whole field.  Strongly suspected; yet a doubt remains."  There is nothing near his position (the declination is marked as uncertain) that fits his description and Dorothy Carlson classifies the number as nonexistent.

 

Harold Corwin concludes "Since there are no galaxies in the area matching JH's description (all are too small), nor are there any one hour preceding or following, or within two +/- degrees of the nominal declination, this may well be a visual illusion of some sort, perhaps caused by scattered light in his telescope."  Curiously, there is an observation by LdR observer R.J. Mitchell on 19 Apr 1855, stating "not L, gbMN and has a patchy look."

The Fourcade-Figueroa Galaxy = ESO 270-017 (possible remant or "shard", resulting from a close interaction between Centaurus A and a spiral galaxy), lies 45' NW.  I was pleased to make a definite sighting as an extremely faint, very elongated glow, particularly extending east-southeast of a mag 11 star.  The very low surface brightness glow was "pointing" just south of a mag 9 star (HD 118087), which is 8' ESE of the mag 11 star (roughly the center of the Fourcade-Figueroa System), and extended at least 2'x 0.4'.  A short extension on the west-northwest side of the star was difficult to confirm but was marginally  glimpsed.  The mag 11 near the center forms the northeast vertex of a small quadrilateral (sides 1.2' or less) of mag 10.5, 12.5 and 13 stars.  The faintest star is superimposed on west-northwest extension of the galaxy.

48" (5/14/12): I was amazed at the beauty of this face-on spiral with two well-defined spiral arms with numerous HII knots and a third faint arm!  The galaxy is sharply concentrated with an extremely bright round core, ~30" diameter.  The slightly brighter and longer southern arm is attached at the north end of the core and winds gracefully counterclockwise for nearly 270”, terminating on the WSW side of the galaxy, 2.4' from center.  This high-contrast arm was sharply defined and contained two knots and brighter segments.  The relatively narrow arm broadens slightly as it unwinds on the south side and is slightly mottled. The brightest HII knot is 10" in diameter and situated slightly further out, 1.9' SW of center.  Beyond this point, the last portion of the arm dims and ends at another 8" knot at the tip, 2.4' WSW of center.  The northern arm is attached on the south side of the core and winds counterclockwise to the north, though only curves gently.  A fairly bright knot (possibly double) is situated along this arm 1.4' NNW of center.  At the north tip of the arm is another fainter knot, 1.8' from center.  A third, vaguely defined arm emerges to the south of the core and unwinds counterclockwise to the west.  A mag 16.5 star marks the tip of this arm.

 

17.5" (5/30/92): moderately bright, large, slightly elongated 4:3 SW-NE, about 4'x3', sharp concentration with a very weakly concentrated halo which fades into the background.  Unusual appearance as suddenly rises to very small bright core 20"-30" diameter.  Spiral structure not seen.

 

WH discovered NGC 5247 = H II-297 = h1649 on 7 Feb 1785 (sweep 369) and logged "pF, L, mbM."  A later observation on 7 Feb 1787 (sweep 732) reads "pB, vL, the greatest part of it vF, unequally bright almost like two joined, the smaller being north preceding [spiral arm?]."  On sweep 354, JH recorded "vF; vL; psb to a brighter kind of nebula; a good type of its class.  It loses itself quite imperceptibly.  Diam of the faint neb = 2'; of the brighter part or nucl = 10 or 15".

48" (5/15/12): beautiful two-armed spiral, very large, elongated ~3:2 SW-NE.  The brightest portion is ~3.8'x2.5' but the faint, outer spiral arms increase the diameter to at least 5'. The galaxy is sharply concentrated with an intense oval core.  The brighter spiral arm is attached to the north of the core, wrapping counterclockwise around the east and southeast side and it is lit up by several fairly prominent knots.  The arm dims fairly abruptly on the southeast side but continues unwrapping to the south, extending outside and just beyond a mag 13.5-14 star 1.7' SSW of center.  A mag 15.3 star is 0.6' N of center, just outside where the arm emerges on the north side.

 

At least four distinct HII knots are in or near this arm, along with brighter segments.  The following designations are from the 1983 Hodge-Kennicutt "An Atlas of H II regions in 125 galaxies".  A faint knot, [HK 83] 26/28 is between this star and the core.  The arm brightens along the east side of the core and include the faint knots [HK 83] 13/15, 28" NE of center, and [HK 83] 5/6 1.0' ESE of center.  The most prominent knot along with this arm is [HK 83] 5/6, 1.2' SE of center.

 

The western spiral arm stretches to the north and also contains several knots (HII complexes/star associations).  The first knot is [HK 83] 63, 0.8' W of center.  A large brighter knot or arc ~1.1' NW of center includes [HK 83] 74/77/81.  A faint knot, [HK 83] 66/71, is near the tip of this arm 1.5' NNW of center.  A similar knot, [HK 83] 53, is 25" SE, on line with the core.

 

18" (6/7/08): bright, large, elongated NW-SE, 3.5'x2.4', sharply concentrated with a very bright, round 25" core.  At 200x, two spiral arms extend out from the central region.  The brightest and longest arm is attached at the west side of the core and gradually sweeps to the north.  A couple of very faint, very small knots are embedded in this arm including one due west of the core.  On the east end of the core a matching arm is attached that curves a bit more as it swings towards the south in a counter clockwise orientation.  A faint star is just north of the central region and a brighter star is 1.7' S of center.

 

17.5" (5/30/92): bright, large, slightly elongated WNW-ESE, 4'x3', well-defined small very bright core, almost stellar nucleus.  A mag 13 star lies 1.7' SSW of center and a mag 15 star is embedded at the north edge of the halo.  Appears slightly mottled or dusty but spiral arms were not seen.

 

WH discovered NGC 5248 = H I-34 = h1650 on 15 Apr 1784 (sweep 194) and recorded "vB, nearly R and cometic but the nucleus is large and seems to consist of bright close stars, resolvable."  On 1 May 1786 (sweep 560) he logged "vB, cL, E from np to sf, a small bright nucleus."

 

R.J. Mitchell, observing on 19 Apr 1855 with LdR's 72", logged "Large and pretty bright, Bright nucleus. Seen as in sketch, but not certain whether the lower branch joins the nucleus or is only the continuation of the upper curve."  On 29 March 1856 he recorded "The preceding arm does appear to originate from the nucleus, which is very bright and oval shaped."   The two brightest spiral arms are clearly shown on Plate XXVIII, fig 29 in PT 1861.

48" (5/4/16): at 610x; very bright, fairly large, striking two armed-spiral.  The central portion only extends ~35", but contains a fascinating structure.  Along the southwest and northeast flanks are sharp-edged prominent "arms", appearing as thin, high surface brightness arcs, with the southern arc slightly brighter.  Both "arms" are slightly convex, appearing like a close pair of parenthesis enclosing the central region!  The northern arm continues as a fainter, but easily visible, fairly thin arc extending west-northwest, and ends just before reaching a mag 15 star [1.7' WNW of center].  A thin, very low surface brightness arm extends west from the southern "parenthesis" towards NGC 5258 (1.4' ESE), but stops just short.  The tip-to-tip distance between the two arms is ~1.6'.

 

On the inside of the two bright "arcs" (blue star-forming arms) there appear to be two thin dust lanes as the surface brightness drops dramatically.  At the center is a fairly faint stellar nucleus.  The overall appearance is very unusual as the surface brightness of the core region is lower than the thin pair of symmetrical arms.

 

17.5" (4/28/90): fairly faint, fairly small, oval 3:2 WSW-ENE, weak concentration.  A mag 14 star is off the west side 1.7' from the center.  Forms a close, interacting pair (Arp 240) with NGC 5258 1.3' SE.

Charles Messier discovered M3 = NGC 5272 = h1663 on 3 May 1764.  WH, observing in 1799 with his 10-foot telescope [8" aperture] at 120x, noted "with an aperture of 4 inches it is resolvable; with 5 easily resolvable; with 6 it is resolvable; with 7 and all open the stars may be easily perceived."  JH recorded (sweep 417) "A most superb object, diam = 10s time in RA. Not less than 1000 stars 11m and under. They run into a blaze at the centre, and form as it were radiating lines and pointed projections from the mass, with many stragglers."

 

Several observation at Birr Castle noted dark lanes or dark notes in the cluster.  On 16 Feb 1869, C.E. Burton recorded "Radiating branches somewhat resembling a St. Andrew's cross, central mass globular.  There seemed to be a bifurcated dark lane in the north segment of the nucleus."  On 21 Apr 1873, Ralph Copeland noted "Several small dark holes on the nf side of the central mass."

18" (7/6/05 - Magellan Observatory, Australia): this large, rich cluster is striking at 128x.  A curving 2' string of four stars mag 6.6-8.6 oriented SW-NE dominate the view, with a pale yellow star and an orange star at opposite ends adding color.  Overall, perhaps 150 stars are visible (many mag 11-12) in an irregular 10' region although the boundaries are arbitrary as the cluster blends into the surrounding fields.  Most of the brighter stars are within a 3' region and in fact the catalogued diameter is only 5'.  At 228x, another fainter layer of 15th magnitude stars emerged from the background.

 

Nicolas-Louis de Lacaille discovered NGC 5281 = Lac I-7 = D 273 = h3531 in 1751-1752 during his expedition to the Cape of Good Hope.  With a 1/2" telescope at 8x he noted a "small indistinct spot."  James Dunlop described "a curved line of small stars, about 1.5' long, with a star of the 7th mag in the north extremity; a group of extremely minute stars on the preceding side of the crescent, and a multitude of very minute stars extended preceding and following."  Dunlop sketched the cluster and observed it 7 times.  JH called it (sweep 596) "a brilliant, compact, milky way cluster.  Rich; irreg fig; gbM; 10' stars 10, 11 and 12m."

17.5" (6/2/00): very nice edge-one situated just 2' SW of a mag 9 star (SAO 44745).  The galaxy is elongated 6:1 NW-SE, ~5'x0.8'.  At the NW edge is a mag 12 star and the extension appears longer is this direction.  The brighter core bulges in the center and the surface brighter is irregular or mottled in different spots.

 

17.5" (6/7/97): fairly bright, large edge-on NW-SE, ~4.0'x0.8'.  Located 1.9' SW of mag 8.9 SAO 44745.  A mag 12 star is superimposed on the NNW extension (2.4' NW of center).  Large, brighter core is weakly concentrated.  Forms a pair with NGC 5296 1.6' SW.

 

8" (5/21/82): faint, moderately large, thin spindle NW-SE.  Located 2' SW of a mag 9 star.

 

WH discovered NGC 5297 = H I-180 = h1668 on 9 Apr 1787 (sweep 725) and recorded "cB, mE about 3' long from 60” np to sf, the brightness confined to a small place."  JH made the single observation "not vB; E 45” np to sf by diagram; gbM."  Nearby NGC 5296 was discovered by LdR's assistant.

14" (4/5/16 - Coonabarabran, 71x): the most noticeable grouping is a large, scattered Milky Way field with ~150 stars in a 12' region.  The brightest star is the variable VX Centauri, at 9th magnitude.  Just off the northwest side is a distinctive 2.5' string of 4 stars (three of these are mag 10.5) oriented NW-SE.   A few arcmin west of the main group is another detached collection (most in an elongated N-S stream, along with several more in a smaller N-S string further west).  The N-S group includes a mag 9.8 star and the smaller string includes mag 9.2 HD 120131 on the south end.  Combining the various subgroups together produces a 20' Milky Way field that stands out reasonably well.

 

JH discovered NGC 5299 = h3537 on 7 Jun 1837 and recorded a "Cl VII class, much more than fill field, a very L and rich milky way cl, quite insulated on the preceding, north, and following sides and nearly so to the south, forming a king of peninsular projection, but much richer than the main portion of the milky way."

 

At his CGH position is a bright Milky Way field with a diameter of  ~30'.  Harold Corwin notes "there is a +30 arcmin error in the GC and NGC declination (too far north)."   RNGC classifies the number as nonexistent.

JH discovered NGC 5307 = h3541 on 15 Apr 1836 and recorded "A very singular object. At first I thought it an ill seen double star; 12..13 = 12..13 mag; distance 2"; but not being able to get it into focus I applied 320 power; which showed it as a hazy, rather elongated, planetary nebulous disc, as if a double star all but obliterated. It is positively not a star. The field is full of stars, two of which are equal to this object in light, but 320 shows them both quite sharp. It is a difficult object to find, and unless in a good night for definition (this is superb) it could not be recovered. The place is well taken. It is the smallest and most difficult planetary nebula I have ever seen.  Figure 15, plate VI, exhibits its appearance with power 320  (N.B. By this figure it would seem rather to belong to the class of double nebulae or double stellar nebulae of the utmost remoteness, than to that of planetary nebulae, properly so called.)"

WH discovered NGC 5318 = H III-422 = h1679 on 2 May 1785 (sweep 406) and recorded "Two, eF, stellar, the time and number taken between them.  The northern one is the faintest; distance about 4 or 5' not far from the meridian."  His position (CH's reduction) is 5' south of NGC 5318 = UGC 8751, the brightest galaxy in the group, and 2' southwest of NGC 5321 = CGCG 190-065.  The separation of these two galaxies is 4.6' with a position angle of 160”, matching his description, though the northern galaxy (NGC 5318) is brighter.  On 3 May 1785 (sweep 407), he noted a nebula he logged as "Suspected, vF, i and vS, but 240 made it appear more like a small patch".  His position is just 6 sec of east of NGC 5318, but he didn't connect this with his observation of 1074 and 1075 just the night before.

 

JH made two observations, recording on sweep 337 "pB; S; R; psbM; 15"; the second of 3 [with NGC 5312 and 5321]."  His position is accurate.  See notes on NGC 5321.  R.J. Mitchell, observing NGC 5318 on 27 Mar 1856, discovered nearby NGC 5319 as well as the two close companions to NGC 5318 -- MCG +06-30-097 0.9' NNW and MCG +06-30-095, 1.9' NNW.  These were not assigned separate GC or NGC designations.

Several sources misidentify MCG +06-30-095 as NGC 5319.  The sketch made with Lord Rosse's 72" clearly shows MCG +06-30-095 and NGC 5319 (3.5' NNE of NGC 5318), but MCG +06-30-095 did not receive a NGC designation as Dreyer may have felt it was part of NGC 5318.

R.J. Mitchell discovered NGC 5319 on 27 Mar 1856 at Birr Castle, while observing NGC 5318.  He labeled this galaxy "C" on the field sketch and simply noted "vF".  Although no separations were estimated, the sketch is accurate enough to identify NGC 5319 = PGC 84061.  See NGC 5318 for more on this sketch.

 

The RNGC and Uranometria Deep Sky Field Guide misidentify MCG +06-30-095 (1.9' NNW of NGC 5318) as NGC 5319.  Corwin agrees that NGC 5319 = PGC 84061.  Malcolm Thomson disagrees and identifies a faint galaxy 5.2' NNW of NGC 5318 as NGC 5319.  See Harold Corwin's NGC identification notes.

WH discovered NGC 5321 = H III-423 = h1680 on 2 May 1785 (sweep 406) and recorded "Two, eF, stellar, the time and number taken between them.  The northern one is the faintest; distance about 4 or 5' not far from the meridian."  His single position is 2' southwest of NGC 5321 = CGCG 190-065 and his description is an excellent fit with NGC 5318 and NGC 5321, which are separated by 4.6' in position angle 160” (NNW-SSE).  The only discrepancy is the northern object (NGC 5318) is brighter.

 

JH made two observations (one good position), calling it "eF; at first sight like a *, but on long attention a pL neb surrounds it" on sweep 337 and "pB; R; smbM." on sweep 74.  But he assumed this object was new and his father's III-422 applied to NGC 5312 = h1676.  As a result, JH is credited with the discovery of NGC 5321 in the GC and NGC.  But NGC 5312 is over 10' southwest of NGC 5318 and the orientation doesn't match WH's description ("not far from the meridian").  Reassigning the historical designations based on this analysis, results in h1676 = GC 3664 = NGC 5312, III-422 = h1679 = GC 3668 = NGC 5318 and III-423 = h1680 = GC 3670 = NGC 5321.

Size 4'x3'

 

18" (7/5/05 - Magellan Observatory, Australia): at 228x, this prominent reflection nebula appears as 2.5' round glow surrounding a delicate pair of mag 10/10.5 stars at 4" separation (h4636).  The nebulosity has a uniform, fairly high surface brightness.  About 2' N and 1.5' NE are a wide pair of mag 12/13 stars.  The star situated 2' N illuminates a small detached piece of nebulosity.  Deep images reveal this nebula is the head of a one degree faint tail (cometary globule CG 12) that streams to the SE.

 

17.5" (5/4/02): this unusual reflection nebula surrounds a bright, close pair of mag 10.3/10.7 stars at 4" (h4636).  The nebula appeared a round, fairly faint, 3' glow surrounding the illuminating stars.  Although the elevation was only 10”, the hazy glow was pretty evident.  A brighter mag 9 star lies 4' ENE.

 

JH discovered NGC 5367 = h3548 on 26 Jun 1834 and recorded "a close double star in a vL, B, luminous atmosphere, 2' diameter. The star A which is quite as bright, has no such atmosphere. The atmosphere is vlbM. The star was not noticed as double till too late for a good measure after I showed the object to my attendant J.S., verified with 240x and 320x. A furious hot north wind, but the definition of stars excellent. It is no illusion, other stars are sharp and brilliant, and have not the least nebulous appearance."  Sketch Plate VI, figure 10.

 

Lewis Swift rediscovered this reflection nebula on 30 Dec 1897, assumed it was new (despite JH's good position) and described it in Popular Astronomy and MNRAS versions of his list (but not in catalogue IX in AN) as "a nebulous star, the only one I have ever found.  The central star is about 8m, and surrounded with an exceedingly faint atmosphere.  An 8m star follows 15s, which was free from nebulosity."  So, Sw XI-162 = IC 4347 = NGC 5367.

 

The nebulosity was included in the Catalogue of Bright Nebulosities in Opaque Dust Clouds by Bernes as No. 147. He describes it as a reflection nebula 4' x 3' (measured north-south by east-west), appearing very bright on the blue plate. He notes that the nebulosity is located on the edge of the cometary globular CG 12, which measures 20'x8'.

48" (4/1/11): the Heron Galaxy was a remarkable interacting pair at 375x and 488x.  The main galaxy (NGC 5395) was extremely bright, elongated 5:2 N-S, 2.5'x1.1', contains a blazing 30" core and a mottled, clumpy appearance.  The most prominent feature is a well-defined, long arm than begins to the north of the core and wraps all the way around the core.  This arm shoots past the core just to its east and heads directly south. The knotty arm then tightly curves back around towards the north on the west side, extending the full length of the galaxy and angling slightly towards smaller NGC 5395.  A dark lane separates the core region from the arm on the west side.  An irregular extension (or part of an arm) branches north from the main arm on the north side of the core and culminates at a brighter region or knot at the north end of the galaxy.  NGC 5394 is 1.9' NW of center and one of the arms of this galaxy attaches to NGC 5395 on the NW side.

 

18" (5/3/08): at 280x appeared fairly bright, very elongated ~3:1 N-S, 1.7'x0.5', brighter 25"x20" core, irregular appearance with a brighter knot or extension on the NW side.  Forms a close, interacting pair with NGC 5394 1.8' NNW.  A very faint extension or haze is off the west side (this is an "arm" that interacts with NGC 5394).  Several faint stars are near including a mag 13.5 1.7' S of center, a mag 15 star 1.9' N of center and another mag 15 star ~1.5' WNW of center.  IC 4356 lies 4' NNW.

 

18" (4/26/08): this is the brighter and larger member of an interesting interacting pair with NGC 5394.  Appears fairly bright, very elongated 3:1 N-S, 1.5'x0.5', broad concentration with a brighter core.  The galaxy has a mottled, irregular surface with a slightly brighter linear streak is on the NE end with the impression of a very faint, round knot on the north end.  An extremely faint hazy extension was highly suspected on the west side in the direction of NGC 5394 located 1.8' NNW of center.  A mag 13.5 star is off the south end.

 

17.5" (6/6/86): fairly bright, elongated NNW-SSE, bright core, small bright nucleus.  A mag 13.5 star is off the south edge 1.7' from center.  There is an impression of a dark lane on the west side and an extremely faint arm beyond the lane (agrees with POSS).  Forms a contact system with NGC 5394 at the NNW edge!

 

WH discovered NGC 5395 = H I-190 = h1723, along with NGC 5394, on 16 May 1787 (sweep 738) and recorded "Two, that of the south [NGC 5395] cB, cL. Distance about 1.5'."  JH made 3 observations and measured a fairly accurate position.

 

Spiral structure was recorded several times at Birr Castle, though the observations are listed in the 1861 and 1880 publications under h1713 = GC 3717 = NGC 5378.  On 24 Apr 1854, R.J. Mitchell logged "centre pB; oval ns, among sev st.  I thought the n end the broader and suspected a dark space preceding nucleus.  A pB patch of neby np."  On 1 May 1854 he added "Singular object; the main body of neb has a B Nucl and is E ns, the southern end bends back suddenly at a sharp angle and extends np past the neb, ending in a B, R patch or Nucl."  On 19 Feb 1855, he reported "Neby seems to reach the knot np.  There is knot or star in the arm p and some condensation in the centre of neb.  I think F neby reaches up to the star north.  Finally, he sketched the pair on 17 Apr 1855 and noted "Mr Johnstone Stoney saw the p branch extend round the south end of the main neb and continued on to the north, when after a second turn it joined the nucleus."

JH discovered NGC 5408 = h3553 on 5 Jun 1834 and recorded "eF; E between 2 vS stars, a little sf."  His position (single observation) is 2' south of the emission-line galaxy ESO 325-047.  This galaxy was misclassified as a planetary in the Sky Catalogue 2000 and the NGC 2000 because it was found by Stock and Wroblewski in 1972 (SKWL 4-9) and listed as a PN in a PK update list (PK 317+19.1) with the comment "extragalactic HII region?".  In 1972, Allen reported this object as a peculiar galaxy with a redshift of 500km/s.  MCG does not label -07-29-006 as NGC 5408.

14 03 28.0 -05 59 04

 

18" (4/30/11): this is a mag 14.7 star on line to the north of the galaxy pair NGC 5426 and NGC 5427 (Arp 271).  Situated 2.9' NNE of the center of NGC 5427.  Tempel made several false sightings (also NGC 5429, NGC 5432 and NGC 5435) around the pair of galaxies.

 

Wilhelm Tempel discovered NGC 5428, along with NGC 5429, 5432 and 5435 in 1882, while observing NGC 5426/5427.  In the narrative portion of this fifth discovery paper (AN 2439) he mentioned that the first two of these were near the interacting pair and one was even on a line with NGC 5426/5427.  Dreyer only gave a single rough position for NGC 5428 and 5429.  Harold Corwin identifies NGC 5428 as a double star on a line to the north of the pair (Arp 271).

V = 11.9;  Size 2.2'x1.1';  Surf Br = 12.8;  PA = 0d

 

24" (7/1/16): at 375x; moderately to fairly bright, elongated 5:2 NNW-SSE, ~2'x0.8', contains a small bright elongated core (bar).  The surface brightness in irregular with some interesting structure.  I had an impression of a spiral arm extending north on the east side of the halo.

 

A fairly faint nonstellar knot (Holm 569B), 6"-8" diameter, is at the southeast end of the bar.  There is a small dip in brightness between the central region and the knot.  Bill Keel considered the knot an extremely luminous HII region, but a recent paper assumes NGC 5430 is a minor merger with the "knot" an off-center dwarf satellite with triggered star formation.

 

17.5" (6/7/97): fairly faint, fairly small, elongated ~2:1 NNW-SSE, brighter core containing a stellar nucleus.  A mag 14-15 "star" is involved at the south-southeast end.  This "star" may confuse the apparent position angle of the galaxy as the major axis (including halo) is N-S.  A faint pair of mag 14.5 stars follows by 2.0'.

 

The stellar object at the south-southeast end is a strong HII emission knot (Ho 569b = Mrk 799a) thought to contain a large number of type-O and Wolf-Rayet stars.

 

17.5" (4/5/97): moderately bright and large, elongated 5:2 NNW-SSE, 2.0'x0.8', brighter core increases to an occasional stellar nucleus.  A mag 15 "star" is close southeast and a mag 14.5 pair at 12" separation lies 2.0' ENE of center.

 

8" (4/24/82): faint, small, round.  Located southeast of NGC 5376 and NGC 5389.

 

WH discovered NGC 5430 = H II-827 = h1738 on 17 Mar 1790 (sweep 948) and logged "eF, S, E, but nearly R."  CH's reduced position is 3' north of UGC 8937.  JH measured an accurate position on a single observation.

18" (4/30/11): faint , 13" pair of mag 14.5 stars resolved at 200x.  Located 5' NE of NGC 5427 (pair with NGC 5426 forming Arp 271).  Other nonexistent objects around Arp 271 are NGC 5428, NGC 5429, NGC 5435.

 

Wilhelm Tempel discovered NGC 5432, along with NGC 5428, 5429 and 5435 in 1882, while observing NGC 5426/5427.  In the narrative portion of this fifth discovery paper (AN 2439) he mentioned this object was about 6' northeast of NGC 5427. Close to this separation is a wide double star with one component a close pair.  Harold Corwin identifies NGC 5432 as a triple star and Dorothy Carlson, in her 1940 NGC Correction paper, identifies NGC 5432 as a double star.

17.5" (6/4/94): this is a close double system with the western component (NGC 5434A) larger and brighter.  Fairly faint, slightly elongated SW-NE, 1.2'x1.0', very little concentration.  Forms a contact pair with NGC 5434B at the northeast end with a separation 1.5'.  The companion appeared faint, very elongated 3:1 ~E-W, 1.0'x0.3', low surface brightness, no concentration.

 

Located between mag 8.8 SAO 120258 6.4' N and a mag 10 star 3.9' S.  Member of the NGC 5416 cluster with NGC 5431 6.4' SW and NGC 5424 6.8' WSW.  Also the NGC 5436, NGC 5437, NGC 5438 trio is in the field to the NE.

 

Wilhelm Tempel discovered NGC 5434 = T VIII-11 on 25 Apr 1883 while observing the NGC 5416 group.  This galaxy was first mentioned (along with the other discoveries in the group) in the narrative portion of list VI, but his published position in list VIII-11 matches UGC 8965.

18" (4/30/11): very faint, close pair of stars located 45" NW of a mag 12.6 GSC star.  The two components are mag 14.6 and 14.7 at 11 seconds difference in RA.  Located 10' NE of NGC 5426/NGC 5427 (Arp 271).

 

Wilhelm Tempel discovered NGC 5435, along with NGC 5428, 5429 and 5432 in 1882, while observing NGC 5426/5427.  In the narrative portion of this fifth discovery paper (AN 2439) he mentioned this object was about 10' northeast of NGC 5427 and that a mag 10-11 star was near. At the required separation is a double star with a mag 12 star 45" northeast.  Both Dorothy Carlson, in her NGC Correction paper and Harold Corwin identify this double star as NGC 5435.

17.5" (6/4/94): faint, very small, faint halo with an abrupt brighter core.  Located 5.2' ENE of mag 8.8 SAO 120258.  First of three in trio with NGC 5437 3.4' SSE and NGC 5438 2.8' NNE in the NGC 5416 galaxy cluster.

 

Wilhelm Tempel discovered NGC 5436, along with NGC 5437 and 5438, on 28 Jun 1883 while observing the NGC 5416 group.  In the narrative portion of list VII he wrote "Since then I have repeatedly seen the new nebula in group III-56 and found 3 new nebula here; these three are in a line, 2'-3' away from each other and follow north near the [mag 9] star, the northernmost is quite bright."  He did not measure positions and only a single rough position is given in the NGC for NGC 5436, 5437 and 5438.  Harold Corwin notes the WH probably saw at least one of these three (H III-57 = NGC 5446) and NGC 5438, the northernmost galaxy, is the most likely (noted by Tempel as the brightest).

17.5" (6/4/94): faint, small, round, even surface brightness.  A mag 12 star is 3.3' SSW of center.  This galaxy is the south member of a trio with NGC 5436 3.4' NNW and NGC 5438 5.2' N.  The double system NGC 5434A and NGC 5434B is 7.5' SW.  Member of the NGC 5416 cluster.

 

Wilhelm Tempel discovered NGC 5437, along with NGC 5436 and 5438, on 28 Jun 1883 while observing the NGC 5416 group. See his description under NGC 5436.  Bigourdan labeled NGC 5436 (furthest west of the trio) as NGC 5437 and claimed this galaxy (CGCG 074-074) as a nova.  Dreyer catalogued it again as IC 4365.  So, NGC 5437 = IC 4365.  See Harold Corwin's identification notes for more.

Wilhelm Tempel discovered NGC 5438 on 28 Jun 1883, and described in the narrative portion of paper VII as one three on a line (with NGCs 5436 and 5437) about 2'-3' apart, with the northernmost galaxy the brightest.  He didn't measure individual positions and only a single rough position is given in the NGC.

 

This galaxy was probable discovered by WH on 19 Mar 1784 and catalogued as H III-57 = NGC 5446, but with a 30 tsec error in RA too far east.  Modern sources identify this galaxy as NGC 5438.

Although all modern sources identify NGC 5441 as this galaxy (PGC 50057), the number is more likely a duplicate of NGC 5440.

 

13.1" (6/18/85): possibly glimpsed as an extremely faint and stellar glow (uncertain sighting) 5' SE of NGC 5440.

 

JH discovered NGC 5441 = h1740 on 11 Mar 1828 and recorded "Taken for II.416 [NGC 5440], which it cannot be if the last obs be correct. vF, S."  His RA is given to the nearest minute of time and noted +/-.

 

RNGC, PGC, MCG, NED, LEDA and SIMBAD identify MCG +06-31-053 as NGC 5441.  If this is Herschel's object it is certainly one of the faintest, if not the faintest galaxy he discovered.  Corwin argues that NGC 5441 is more likely a duplicate observation of NGC 5440, despite JH's comment, and I agree based on the view through my 24-inch.  See Corwin's identification notes.

18" (6/21/03): at 215x this fairly prominent HII region appeared as an elongated patch oriented NNW-SSE, perhaps 25"x8", located just south of a mag 13.5 star.  At 323x this patch clearly resolved into two sections -- within 30" of the star is a very compact knot, ~6"-10" diameter.  There may be a small gap to the south with a larger extension to the SSE (this is NGC 5450).  Located on the opposite side of M101 as NGC 5462.

 

17.5" (6/7/97): brightest HII region on the preceding side of M101 located 7.8' SW of center.  Appears as a very elongated glow NW-SE situated just south of a mag 13.5 star.  A very small knot is partially resolved at the north edge within a common halo with the extension to the SE.  Harold Corwin identifies these two components as NGC 5447 and NGC 5450.

 

13": this is a knot in an outer arm of M101 on the western side.  Easily visible, compact, round.  Located symmetrically opposite from NGC 5462 on the opposite side of the core.

 

WH discovered NGC 5447 = H III-787 on 14 Apr 1789 (sweep 921) and noted "vF, vS."  His position (CH's reduction) is 20 sec of RA following the bright HII complex (NGC 5447/5450) on the southwest side of M101.  This region was clearly marked Iota on the sketch of the HII regions by Lord Rosse in the 1861 and 1880 publications.

 

JH assigned this knot two GC numbers as he was not sure if his father's object was the same as the one on the Lord Rosse woodcut, but both GC designations were combined into NGC 5447.

WH discovered NGC 5448 = H II-691 = h1743 on 15 May 1787 (sweep 736) and recorded "pB, pL, E nearly in the parallel, mbM."  His position is accurate. JH called this galaxy "pB; L; vmE; psmbM; 4' l, 20" br; a ray with a nucleus."  The RA in the RNGC is 1.0 minute too large.

NGC 5449

18" (6/21/03): marginal object at 323x, but backing down to 215x a weak but definite glow was visible, perhaps 15"-20" diameter.  Located 3.5' N of NGC 5457.

 

17.5" (6/7/97): extremely low contrast HII knot in M101.  Highly suspected hazy spot 3.5' N of NGC 5457 but difficult to confirm.

 

Bindon Stoney, LdR's assistant, discovered the numerous knots in M101 during observations in 1851.  Samuel Hunter sketched NGC 5449 in Apr 1861 based on multiple observations. The NGC position (based on the sketch) is just 1' too far south.

NGC 5450

14 02 29.5 +54 16 14

 

18" (6/21/03): See description for NGC 5447.  NGC 5450 appeared just resolved from NGC 5447 at 323x and was an elongated patch oriented NNW-SSE, ~20"x6".  The entire complex spans ~45".

 

17.5" (6/7/97): this is the bright HII region on the west side of M101 8' SW of center.  Connected with NGC 5447 (see description). Appears as a very elongated glow NW-SE just south of a mag 13.5 star.  A very small knot is partially resolved at the north edge (NGC 5447) within a common halo with NGC 5450.

 

Bindon Stoney, LdR's assistant, discovered the numerous knots in M101 during observations in 1851.  Samuel Hunter sketched NGC 5449 in Apr 1861 based on multiple observations.  JH later computed the GC position based on the sketch as 33" south of NGC 5447.  Harold Corwin identifies NGC 5450 as the southeast component of the HII region connected with NGC 5447.  Dreyer modified the position of NGC 5447 2' further north, so the NGC position of the pair is further apart.

NGC 5451

14 02 37.0 +54 21 45

 

18" (6/28/03): very difficult, low surface brightness glow, ~10"-15" in size, requiring averted vision to glimpse.  More difficult than two mag 15.5 stars separated by 13", which are location 1' WSW.  The combined glow of these stars could easily mislead the observer into logging these as NGC 5451!

 

18" (6/21/03): initially I picked up a small, hazy glow nearly collinear with a mag 12.9 star just north of the core of M101 and a slightly fainter star due west.  But in good moments, this very small glow resolved into two stellar objects, probably appearing slightly hazy due to the background glow of the outer halo.  After a more careful view, I noticed an extremely faint knot with averted vision, ~15" diameter, located ~2' ENE of this pair -- this is NGC 5451.  It seems likely that the observation from 6/7/97 refers to the pair of faint stars that initially confused me.

 

17.5" (6/7/97): this is a difficult, low contrast HII region in M101 located ~5' WNW of center.  Appears very faint, extremely small, round, starry center?

 

Bindon Stoney, LdR's assistant, discovered the numerous knots in M101 during observations made in 1851.  Samuel Hunter made a remarkly accurate sketch of M101, along with the various knots, in Apr 1861 based on multiple observations.  JH estimated the position in the GC based on this sketch.

18" (6/21/03 and 6/28/03): the following HII regions were observed --

NGC 5447: at 215x this fairly prominent HII region appeared as an elongated patch oriented NNW-SSE, perhaps 25"x8", located just south of a mag 13.5 star.  At 323x this patch clearly resolved into two sections -- within 30" of the star is a very compact knot, ~6"-10" diameter.  There may be a small gap to the south with a larger extension to the SSE (this is NGC 5450).  Located on the opposite side of M101 as NGC 5462.

 

NGC 5449: marginal object at 323x, but backing down to 215x a weak but definite glow was visible, perhaps 15"-20" diameter.  Located 3.5' N of NGC 5457.

 

NGC 5450: just resolved from NGC 5447 at 323x and was an elongated patch oriented NNW-SSE, ~20"x6".  The entire complex spans ~45".

 

NGC 5451: very difficult, low surface brightness glow, ~10"-15" in size, requiring averted vision to glimpse.  More difficult than two mag 15.5 stars separated by 13", which are location 1' WSW.  The combined glow of these stars could easily mislead the observer into logging these as NGC 5451!  In fact on 6/21/03 I initially picked up a small, hazy glow nearly collinear with a mag 12.9 star just north of the core of M101 and a slightly fainter star due west.  But in good moments, this very small glow resolved into two stellar objects, probably appearing slightly hazy due to the background glow of the outer halo.  After a more careful view, I noticed an extremely faint knot with averted vision, ~15" diameter, located ~2' ENE of this pair -- this is NGC 5451.

 

NGC 5453: required averted and concentration to confirm a small, low surface brightness glow, just visible over the background glow of the spiral arm this HII region resides.  In fact, between NGC 5453 and the core is an inner arm which contains a couple of HII knots which are more evident!

 

Anon knot: two small, low contrast knots are visible in the spiral arm that is attached on the west side of the core of M101 and wraps around the south side towards the east. These are situated just 1.7' SW of the center of M101.  Although this knotty structure does not have a NGC number it is slightly more evident than a few of the faintest NGC HII regions.

 

NGC 5455: compact knot, round, easily identified as forms the southern vertex of a triangle with two 13th magnitude stars to the NW and NE.  At moments, a stellar nucleus or superimposed star pops out at 323x.

 

NGC 5458: very faint glow 3' S of the core of M101 on a line between a 13th magnitude star ~7' S of the center of M101.  Requires averted for a definite sighting and appears to have a low, even surface brightness, ~20" diameter.  Easier to view than NGC 5453.

 

NGC 5461: at 435x (5.2mm Pentax) a fairly bright quasi-stellar knot is attached at the NE end with a relatively faint extension (even surface brightness) extending to the SW.  On 6/21 at 215x, this prominent HII region has a high surface brightness and stands out well.  Increasing the power to 435x, there is a stellar or quasi-stellar core offset at the NE end with a faint extension to the SW.  Backing down to 323x and using a UHC filter, the glow decreases in size, but the star-like core seems to increase slightly in contrast.

 

NGC 5462: this HII region is probably the largest continuous piece.  It appears very elongated 3:1 or 7:2 SW-NE, roughly 60"x18". On 6/21 appeared fairly bright and relatively large, elongated 3:1, ~50"x17" SW-NE.  This HII region has an irregular surface brightness with a bright, nearly stellar knot at the NE end.

 

NGC 5471: highest surface brightness of any of the HII regions in M101.  Appears very similar to a small, elliptical galaxy -- even contains a small, brighter core.  Situated beyond the main glow of the galaxy, 11.5' NE of the core of M101.  On 6/21 at 323x appears similar to a compact, round galaxy.  Furthest NE of all the HII regions and well separated from the main glow of M101.  Interestingly, this was one of the few HII regions that did show a positive contrast response to a UHC filter at 161x and 215x.

 

13.1" (6/4/84): four HII regions resolved including NGC 5447, NGC 5458, NGC 5461, NGC 5462.

 

13.1" (4/24/82): fairly bright, very large, round, about 20' diameter, bright core.  Fairly low surface brightness but beautifully resolved into several distinct arms and sections of arms with a pinwheel design.  Obvious mottling along the spiral arms which appear clumpy with two or more easily recognized HII regions. At least six stars are superimposed.

 

Pierre MŽchain discovered M101 = NGC 5457 = h1744 on 27 Mar 1781.  On 14 Apr 1789 (sweep 921), WH described "a very bright small nucleus with extensive nebulosity, pretty well determined on the preceding side, but very diffuse to the north following . Includes the two following nebulae [III-788 = NGC 5461 and III-789 = NGC 5462], and seems to extend 20', perhaps 30' or more."

 

Bindon Stoney (LdR's assistant) sketched the various HII knots, spiral arms and superimposed stars and measured offsets in 1851.  Samuel Hunter's superb sketch from 29 Apr 1861 was included at the last minute in the 1861 publication.  This is probably the finest and most accurate sketch of a spiral galaxy done at Birr Castle and is very favorably compared with the DSS.

This is one of the southernmost clusters visible from Northern California sites, but was still very pretty.

 

James Dunlop discovered NGC 5460 = D 431= h3555 on 7 May 1826 from Parramatta with his 9.75-inch speculum reflector and described "a curiously curved line of small stars of nearly equal magnitudes; two stars of 7th magnitude following."  He observed the cluster 3 times.  JH made his first observation on 6 Aug 1831 and recorded "a region of large, bright stars, 8, 9...etc. mag; a very coarse cluster. Place that of a brilliant group, one of which is a double star class III." Two nights later he recorded it as "Place of a double star in a semi-elliptic group forming part of it, but insulated in a large scattered cluster or tract of bright stars." On a later sweep he logged "a region of large stars very loosely distributed, but which yet decidedly form a cluster. Place that of a pretty close double star (four arcseconds) in the middle of a group of 8. The cluster is 30' diameter, and is divided into distinct groups."

There is are no nearby galaxies and both Dorothy Carlson and Harold Corwin identify NGC 5467 as a single star.  Independently, Bigourdan also logged this star as nebulous, so it was catalogued again as IC 973.  Assuming the same star fooled both Tempel and Bigourdan, this is the only known case where a single star has both an NGC and IC designation!  Bigourdan's IC 974 is another nearby star he thought to be nebulous.

18" (6/30/11): faint, very small, irregularly round, 18" diameter, weak concentration.  A small right triangle of mag 13-14 stars [sides 1.1', 1.4', 2'] is close SW.  Brighter of a pair with UGC 9084 4.3' WNW.

 

The identification NGC 5469 = CGCG 74-136 is uncertain but if UGC 9084 was assumed by Tempel to be NGC 5482, then his NGC 5469 refers to CGCG 74-136.  CGCG 74-141 and -142 lie ~9' ESE.  See notes for NGC 5511, which may be CGCG 74-141.

 

17.5" (6/8/02): faint, very small, round, 15" diameter.  Just following a small triangle of mag 13-14 stars.  Forms a pair with UGC 9084 4.3' WNW.  NGC 5511 lies 10' ESE (all three faint galaxies collinear).

 

Wilhelm Tempel discovered NGC 5469 in 1883 while observing the NGC 5416 group.  In the narrative portion of paper VIII (AN 2527) he writes (translated by Wolfgang Steinicke) "III 59 [= NGC 5482] is 9s preceding, 2 1/2' south of a faint star 11m; the nebula is small and has in its center a faint star with very little nebular matter. Following the star 11m, there is at 15s, parallel to it [the star or NGC 5482?] a nice round nebula, III, without a faint star [in the center]. This nebula is also new."  There is no object matching this description or at the NGC position.

 

Instead, Harold Corwin suggests that Tempel probably confused UGC 9084 for NGC 5482.  This would imply, based on Tempel's description, that CGCG 074-136 = NGC 5469.  See Corwin's notes. The RNGC has misidentified CGCG 074-062 as NGC 5469. This galaxy is a close companion of NGC 5423 and is roughly 90' from the NGC position.

18" (6/28/03): highest surface brightness of any of the HII regions in M101.  Appears very similar to a small, elliptical galaxy -- even contains a small, brighter core.  Situated beyond the main glow of the galaxy, 11.5' NE of the core of M101.

 

18" (6/21/03): at 323x appears similar to a compact, round galaxy.  Furthest NE of all the HII regions and well separated from the main glow of M101.  Interestingly, this was one of the few HII regions that displayed a positive contrast response to a UHC filter at 161x and 215x.

 

17.5" (6/7/97): this is one of brightest HII regions in M101, on the extreme NE end of the galaxy 11.5' from center.  Appears as a moderately bright knot, ~20" diameter.  This HII region stands out well due to its isolation and fairly high surface brightness with crisp halo.  Incorrectly identified as a galaxy in the MCG.

 

Heinrich d'Arrest discovered NGC 5471 on 22 Aug 1863 with the 11-inch refractor at Copenhagen and measured it on 5 different nights.  He noted the mag 13 star that precedes by 9 sec of RA and questioned if this object was H III-789 with a 30 sec error in RA.  MCG includes this HII region as a galaxy (MCG +09-23-030).

18" (4/26/08): at 220x this is a fairly bright, large, asymmetric galaxy ~3.0'x2.5'.  The galaxy is moderately concentrated with an 0.8' core that is embedded at the north end of the galaxy!  The halo of the galaxy is a slightly elongated N-S oval glow with the core internally tangent on the north side.

 

18" (6/17/06): fairly bright, large, with an irregular asymmetric appearance.  Broadly concentrated to a 1' brighter core that resides on the north edge of the galaxy.  The 2.5' halo is slightly elongated N-S and spreads out from the core only towards the south!  The halo has a slightly mottled texture and fades at the periphery.  With averted vision the size increases to nearly 3'.  A mag 13.5-14 star is just north of the offset core.  A mag 13 pair at 14" lies 9' ESE.  This disturbed galaxy is a member of the M101 group.

 

17.5" (5/22/93): fairly bright, large, irregular round or slightly elongated SSW-NNE.  Very unusual appearance as a large brighter knot of 0.8' diameter or a very eccentrically placed core is located at the NE edge.  The halo extends generally SW from this brighter spot.  About 3' diameter, no brightening at the geometric center.  A mag 14 star is just off the NE edge 0.8' beyond knot.  Located 45' SSE of M101 and the asymmetry is from being tidally deformed by M101.

 

WH discovered NGC 5474 = H I-214 on 1 May 1788 (sweep 840) and recorded "cB, terminating abruptly to the north, and diffused to the south."  Indeed, this galaxy is very asymmetric, with the nucleus at the north edge of the galaxy!

 

Samuel Hunter, observing with LdR's 72" on 14 May 1861, logged "vL and probably of interest.  The nucleus is on the n edge and appears to have a dark lane around it; the faint nebulosity spreads out from it like a fan with the edges rather brighter than the centre."

Edward Swift, Lewis' 15 year-old son, discovered NGC 5502 = Sw I-29 on 9 May 1886 and recorded "eeeF; pS; R; ee diff; between 2 stars, one a wide double."  There is only a single galaxy here (MCG +10-20-077) but Lewis found it again two nights later, thought it was new and it was listed a second time as Sw I-30 (later NGC 5503), with the description "eeeF; vS; R; ee dif; forms with 2 stars a right angle triangle."

 

In the introduction to his second discovery list, Swift mentions Sw I-29 should probably be struck out without giving an explanation. Nevertheless, Dreyer catalogued both entries as NGC 5502 and 5503.  Since NGC 5502 was discovered first, this designation should take historical precedence. Swift made several other duplicate observations of galaxies, though this is an unusual case involving a father and son!  See Corwin's notes.

18" (6/30/11): faint to very faint, very small, slightly elongated, 0.3' diameter.  Forms a close pair with fainter CGCG 074-142, just 1.1' SE, which appeared extremely faint, very small, round, 12" (probably just the core seen).  CGCG 74-136 lies 9' W.

 

The identification of NGC 5511 with either galaxy in this pair is uncertain because of Hough's confusing description, but CGCG 074-141 has a higher surface brightness than -142, so seems to be the more likely of the two candidates.

 

17.5" (6/8/02): extremely faint, small, irregular or slightly elongated, 0.4'x0.3'.  Only a single galaxy was seen (either CGCG 074-141 or -142, which form a 1' pair) in poor seeing ~3' W of a mag 10.5 star.  Slightly brighter CGCG 74-136 (which may be NGC 5469) lies 10' WNW.

 

George Hough discovered NGC 5511 on 10 May 1883 with the 18.5-inch Clark refractor at Dearborn Observatory while searching for d'Arrest's comet.  His position is ~2.5' east of VV 299, a 1' pair of galaxies (CGCG 074-141 and -142).  His description reads "small, very faint, star 10m, 10m preceding."  Ignoring the typo, there is no 10th mag star preceding, though a mag 10 star is ~3.5' east-southeast.  Assuming Hough found one of the pair, CGCG 074-141 is more likely based on my visual observation.  CGCG doesn't label either galaxy as NGC 5511.  See Harold Corwin's identification notes for more on this story.

R.J. Mitchell discovered NGC 5524 on 19 Apr 1855 while observing NGC 5529.  Although no absolute position was given, he placed this nova 6' west and 1' north of NGC 5527 (another LdR discovery).  JH was confused which two objects were being offset and the GC/NGC position is erroneous, but falls closest to CGCG 191-067.  Most modern catalogues misidentify this galaxy as NGC 5524. According to Harold Corwin's analysis, CGCG 191-067 = NGC 5527 and the best candidate for NGC 5524 is the unequal double star at the position given here.  This implies that Mitchell should have placed this double star 6' west and 1' south of NGC 5527.  In November 2014, though, he decided a faint star, which is 5.5' from NGC 5527 and north of it by just under 1', is more consistent with Mtchell's estimates.

R.J. Mitchell discovered NGC 5527 on 19 Apr 1855 with LdR's 72" during an observation of the NGC 5529 field.  This nova was described as "another vF about 15' np [of NGC 5529]."  CGCG 191-067 is a good match with this description (the actual separation is 17').  Modern galaxy catalogues misidentify CGCG 191-067 as NGC 5524 (this was also Bigourdan's interpretation).  But NGC 5524 derives from Mitchell's description "another eeF about 6' preceding and 1' north of this last [NGC 5527]."  Corwin identifies NGC 5524 as an unequal double star, located 6' preceding and 1' south of NGC 5527.

 

RNGC misidentifies MCG +06-31-085 as NGC 5527.  MCG +06-31-085 is an extremely low surface brightness galaxy 0.3 min of RA west and 2' south of NGC 5529.  Finally, Rosse also mentions a "vF neb sf [NGC 5529], and in this direction is CGCG 191-071 (see observing notes).  Unfortunately this object didn't receive a NGC number probably due to the lack of offset or a sketch.

JH discovered NGC 5545 on 27 Apr 1827 as he noted "a double nebula [with NGC 5544] which run together pos 10” nf by diagram."  Bindon Stoney, LdR's assistant, found the pair on 10 Apr 1852 and noted "either a double nebula or 2 knots of one neb."  R.J.

Lewis Swift discovered NGC 5565 = Sw I-34, along with NGC 5558 and 5564, on 14 Jun 1884 and recorded "S; vvF; R; v diff."  His position is 30" south of Sw I-33 = NGC 5564, which is probably a duplicate of NGC 5554 (discovered earlier by Marth).  Assuming this is true, his offset suggests NGC 5565 refers to a mag 15.5 star situated 1.8' southeast of NGC 5554.

 

Harold Corwin mentions that Swift called NGC 5558 and 5564 "np of 2" and "sf of 2" and carefully describes the nearby field, although the positions imply NGC 5564 and 5565 would be a much closer pair.  Another possibility, is that NGC 5565 is actually a duplicate of NGC 5563.  In any case, there are only three galaxies in this area, and all were found previously by Marth.  See Corwin's identification notes.

WH discovered NGC 5570 = H III-12 = h1781 on 23 Jan 1784 (sweep 110) and recorded "a nebula, it is excessively obscure."  His published description adds "vF, forming an arch with 3 stars."  There is nothing near his position.

 

Harold Corwin suggests NGC 5570 is the first observation of NGC 5519.  He notes "NGC 5519 indeed forms an arch with two stars west and southwest, and a third is superposed on the galaxy.  WH's observation puts N5570 21m 15s p, 0d 34' s of 31 Bootis.  This is 6 minutes of time off the position of N5519.  I think that the "21m" is a transcription error and should read "27m."  In that case, the RA as well as the Dec and the description would match N5519."  Interestingly, it appears he observed this galaxy again on 12 May 1793 (sweep 1043) and noted "2 vS stars with nebulosity suspected between them."  His position is 3' too far south, but matches the mag 14.5 star attached to the following end and the nucleus of the galaxy.  He didn't assign an internal discovery number on this observation, so there was no H-designation.

 

Searching for his father's III-12, JH recorded h1781 on 9 May 1828 as "Not vF; S; R; bM. (RA by working list.)"  His position is roughly the same as his father's.  On the second sweep he simply noted "Seen.  as also III. 551 [NGC 5546] in the same parallel, but considerably dist in RA."  The RNGC and PGC (but not MCG or CGCG) misidentify CGCG 047-007 as NGC 5570.  This galaxy is roughly 1 min of RA west of WH's position and 5' south, but doesn't match his description of "forming an arch with two stars."  Still, it's possible CGCG 047-007 = h1781.

Guillaume Bigourdan discovered NGC 5571 = Big. 73 on 27 May 1886.  His position in his second Comptes Rendus list corresponds with a small group of 4 stars.  According to Harold Corwin, Bigourdan thought there was some nebulosity on his first observation (used in the NGC), but he resolved the stars on the second attempt.  RNGC incorrectly equates NGC 5571 with NGC 5579.  See Corwin's identification notes.

George Johnstone Stoney discovered NGC 5577 on 26 Apr 1849 with LdR's 72" and recorded "16' nf 1783 [NGC 5576] there is a L, F ray about 4.5'x1', gvlbM."  Two years later (12 May 1850), he described this "Nova" as "pB, D* close preceding, * in nf edge."   Although the identification is certain, the separation is only 10' northeast of NGC 5576 as noted by d'Arrest, who measured an accurate position.

Lewis Swift found NGC 5578 = Sw I-35 on 22 May 1884 and recorded "vF; vS; lE; mbM to nucleus."  His position is 15 sec of RA following NGC 5575 (discovered by Marth in 1864), so it's a bit surprising that Dreyer assumed it as new, and recatalogued it as NGC 5578.  In any case, NGC 5575 = NGC 5578, with NGC 5575 the primary designation.

Harold Corwin suggests h1789 may be a duplicate observation of NGC 5589.  JH placed NGC 5588 about as far south of NGC 5590 as NGC 5589 is north and RA's are identical, so if he reversed the direction of the declination offset from NGC 5590, then his position for h1789 = NGC 5588 would match NGC 5589.  Discussed in private email on 12 Sep 1994.  See Corwin's identification notes for his summary.

18" (7/5/05 - Magellan Observatory, Australia): picked up at 76x as fairly striking elongated group of stars.  At 228x, this is a distinctive group of 11 brighter mag 10/11 stars including a nice pair (h 4675 = 10/11 at 8") and perhaps 30 stars total in a 7'x2.5' group that is quite elongated E-W.  The cluster is well-detached in the field.  In the center is a nearly 1.5' region devoid of stars which separates the cluster into two subgroups with the double star just following this vacuity.  Appears fully resolved, even at low power.

 

James Dunlop discovered NGC 5593 = D 350 = D 357 = h3566 on 8 May 1826 and described D 350 as "a curved line of small stars, south preceding a star of the 7th magnitude".  Although his position is well off, the description applies though the star of 7th magnitude - not the cluster - is south-southwest.  For D 357 he logged "a very extensive cluster stars of mixed small magnitudes; the stars appear to be either congregating together in different parts of the cluster, or breaking up; there are several groups already formed, the whole cluster is composed of lines of stars, but no general attraction towards any particular point."  Although the two descriptions are quite disparate, they both seem to describe the cluster and general region.

WH discovered NGC 5594 = H III-135 on 19 May 1784 (sweep 220) and noted "eF, vS, stellar, 240x verified it."  In the notes section of the NGC, Dreyer says there was a discrepancy of 10' in the declination from Caroline Herschel's position and Auwers'.  He used CH's [her position was actually 6' off in dec) but Auwers' was better.  In Dreyer's 1912 correction list he also notes "the PD should be 63” 8'."  Using this correction, H III-135 = CGCG 133-046.

 

Stephane Javelle independently found the galaxy on 14 Jul 1895, measured a good position and included it his list III-1306.  Dreyer recatalogued it as IC 4412 and both CGCG and MCG label this galaxy as IC 4412.

Sir Robert Ball, an assistant on LdR's 72" telescope, discovered NGC 5601 on 27 Mar 1867.  Under the listing for GC 3867 [=NGC 5598] and GC 3871 [=NGC 5603] is the comment "One or perhaps 2 novae; 2nd may be a *".  Although there was no diagram or offsets in the 1880 LdR monograph, Dreyer published a good position for NGC 5601 in the GC Supplement (5770) and NGC.  The second nebula that Ball suspected is probably UGC 9216.  The MCG selection for NGC 5601 appears to be NGC 5603, while its choice of NGC 5603 is UGC 9216.

The RNGC and PGC misidentify CGCG 337-010 = PGC 51356 as NGC 5620.  This galaxy is two degrees south of WH's position.  A better candidate is CGCG 337-009 = PGC 51326, situated 13' due north of WH's position.  This galaxy is quite faint (mag 15.6pg) and between two brighter stars that WH would probably mention.  Finally, NGC 5607 = UGC 9189 is 2.5 min of RA due west.  This galaxy is significantly brighter than the CGCG and was in fact found by WH two weeks earlier and recorded as II-331.  Corwin suggests NGC 5607 as the most likely candidate.

WH discovered NGC 5621 = H III-14? = h1807 on 30 Jan 1784 (sweep 134) and logged "I suspect an almost imperceptible cl of stars or nebulosity.  It precedes 31 Bootis 12.5 min, 9' north."  There is nothing near this position, but JH recorded h1807, 82 sec of RA preceding, which he took as III-14 on 17 Apr 1830, noting "the faintest possible".  Bigourdan was unable to find this object, although he suspected a nebula at JH's position.  Karl Reinmuth, in his photographic survey "Die Herschel Nebel", took CGCG 047-050 as NGC 5621 and described "F, cS, E, r; *14.7 p 2.0', *12.7 ssp 1.7'."

 

At the position of h1807, used in the GC and NGC, is a 26" pair of mag 15.5-16 stars and a third mag 17.5 star.  Whether this is III-14 is unknown.

George Bond discovered NGC 5632 = Au 33 = HN 11, along with NGC 5651 and 5658, on 9 Feb 1853 with the 15-inch Merz refractor during the Harvard Zone observations.  Auwers included this object in his 1862 table on new nebulae.  Bond's discovery position in AN 1453 is just 30" north of a mag 15.4 star.  But Yann Pothier discovered in 2015 that Bond misidentified his offset star as Star 118 instead of 129 (in Annals of Harvard Observatory, Vol I, part II, p 282-3).  Once corrected, his position ("Another nebula precedes No. 118 2m 30s, and is in the same declination with star No. 118.") is 28 seconds of RA east of NGC 5731 and the other two objects also match up with galaxies.

WH discovered NGC 5640 = H III-949 on 20 Dec 1797 (sweep 1074) and noted "eF, S, lE near the parallel [in RA]."  Dreyer mentions in the collected papers of WH that Bigourdan twice failed to find this object, but the RA may be nearly 2.0 tmin following the NGC position using a different reference star.

 

Corwin suggests NGC 5640 = CGCG 353-035.  This galaxy is 1.1 tmin east and 3' north of the NGC position though at this declination the difference in RA is negligible.  Using the position of NGC 5712 as a reference (the next object in the sweep), the position for III-949 is just 30 tsec west of CGCG 353-035, so this seems likely.  Another possibility is that NGC 5640 = CGCG 353-034 (same declination) which is visually brighter and elongated roughly east-west, but further off in RA.  See Corwin's notes for more on the story.

24" (4/11/08 - Magellan Observatory, Australia): at 260x I was very impressed with this large, bright barred spiral.  The halo is slightly elongated, ~3.5'x3.0' and sharply concentrated with a very bright, small, core.  Extending through the center is a brighter bar oriented E-W with a star superimposed on this bar to the west of the core.  A second superimposed star lies 35" to the south and continuing on this line is a third star just at the edge of the halo, 1.7' S of center.  At the east end of the bar a slightly enhanced arc sweeps clockwise to the north and a similar enhancement on the west side sweeps to the south.  The faint arc or arms wrap around 180” making a complete outer ring. The central bar and the outer ring together form the Greek letter "theta".  Situated in a fairly rich Lupus star field.

 

18" (7/5/05 - Magellan Observatory, Australia): fascinating glimpses of structure at 228x!  This galaxy is fairly bright and large, round, ~3.5' diameter.  The surface brightness is clearly patchy in the halo due to the strong impression of clockwise spiral structure but there was only a broad, weak concentration in the center except for a sharply concentrated, bright 15" nucleus. A broad spiral arm is attached on the east side of the galaxy shooting sharply to the north.  There is an impression of another spiral arm attached on the west side of the galaxy and sweeping towards the south in a clockwise orientation, though this structure is not as well defined.  A string of five stars angling SSE to NNW appear to puncture the galaxy on the south side with the northern two stars superimposed on the west side of the galaxy with the last star in the chain just west of the nucleus.  Located in a star field densely peppered with stars.

 

13.1" (4/10/86): faint, diffuse, fairly small.  Two stars are superimposed on the south and SW side.

 

James Dunlop probably discovered NGC 5643 = D 469 = h3572 on 1 Jun 1834 and recorded "an exceedingly faint, extended nebula, about 10' long; rather ill-defined."  His position is 7' due east of the galaxy.  JH first observed the galaxy on 1 Jun 1834 and logged "pB, L, vgbM, 2', resolvable, or with stars."  Two nights later he noted "pF, L, R, vglbM; has many stars intermixed."

Guillaume Bigourdan found NGC 5648 = Big. 74 on 23 May 1887 and recorded "mag 13.4-13.5, 30" dia, without nucleus, distinct from GC 3911 [NGC 5649].  His position matches NGC 5649 = h1824, although because JH's position was poor, Bigourdan thought it was new.  Later, Bigourdan realized the equivalence (given in the 17 Jun 1901 Comptes Rendus paper) and the IC 2 Notes state NGC 5648 = NGC 5649.

 

RNGC, UGC, MCG and RC3 label this galaxy as NGC 5648, but by historical priority, NGC 5649 should be the primary designation.  See Webb Society Quarterly Journal for July 1991.

JH discovered NGC 5649 = h1824 on 4 Apr 1831 and noted "the faintest perceivable; the first and northern of 2".  His position is 1.5' southeast of UGC 9330.  He mistakenly assumed his father's III-645 applied to this galaxy, instead of NGC 5655, which he claimed as a  "nova".

 

The identifications are confused in all the major catalogues.  NGC 5649 is labeled as NGC 5648 (a duplicate observation by Bigourdan) in the RNGC, UGC and RC3 but as NGC 5649 in MCG.  By historical priority, H III 645 = NGC 5649 should apply.  RNGC, UGC, MCG and PGC misidentify NGC 5655 = UGC 9333 as NGC 5649.  See Corwin's notes.

Lewis Swift found NGC 5650 = Sw VI-67 on 19 Apr 1887 and recorded "vF, pS, R."  His position is 7 sec of RA west and 0.5' north of NGC 5652 (discovered by WH), but there is only a single galaxy here.  Curiously, Swift's description doesn't mention nearby NGC 5652, so apparently didn't realize it was catalogued in the GC.  RNGC equates NGC 5650 = NGC 5652, and Harold Corwin concurs.

George Bond discovered NGC 5651 = Au 34 = HN 12 on 9 May 1853, along with NGC 5632 and 5648, with the 15-inch Merz refractor during the Harvard Zone observations.  At his position in AN 1453 is a very faint star.  But Yann Pothier discovered in 2015 that Bond misidentified his offset star (#118 instead of #129) in Annals of Harvard Observatory, Vol I, part II, p 282-3. Once corrected, Bond's offset ("A round nebula precedes No. [129] 3 s 7' North of it." points directly to NGC 5713.  RNGC classifies the number as nonexistent.

Truman Safford independently found this galaxy on 11 May 1886 with the 18.5-inch refractor at the Dearborn Observatory.  His RA for Sf 13 was 1 minute too large, so Dreyer assumed it was a new object and catalogued it as IC 1026. So, NGC 5653 = IC 1026.
