Later observations couldn't confirm the spirality, though the galaxy is
included in the list of 14 "Spiral or curvilinear" nebulae in LdR's

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

(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.

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.

definite straight cut 40" broad; pos = 120.3 ; dimensions of the nebula 5'

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

(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.

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

(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."

(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.

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."

discovered NGC 5174 = H III-45/46 = h1612 on 15 Mar 1784 (sweep 174) and logged
"Two, vF. I took them at
first for only one, but 240 showed two eF nebula as it were running into each
other and of considerable extent; 157 showed also a division between their
center after I had seen them with 240." There is only a single galaxy here and NGC 5175 is very
likely a star at the south end of the galaxy.
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.

(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

identify.

(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
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).
18"
(7/2/11): first view of type IIb supernova 2011dh in M51, which was discovered
after the last time I could observe.
The magnitude was ~13.3.
The progenitor star of SN 2011dh is possibly an extremely unusual yellow
supergiant with a massive blue companion that was leeching material off the
yellow supergiant.

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.

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. Using his 12-inch (20-ft focal
length) on 20 Sep 1783, William Herschel commented (clearly interested if it
was a cluster), "most difficult to resolve; yet I no longer doubt. In the southern nebula I saw several
stars by various glimpses, in the northern also 3 or 4 in the thickest part of
it, but never very distinctly."
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). John Herschel 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).
Probably using
LdR's drawing as a "guide", William Lassell sketched the spiral
structure and connecting arm on 12 May 1846 (in his notebook) with his 24"
equatorially mounted reflector. Jean Chacornac made an excllent pencil sketch
(unpublished) in 1862 using the 31" silvered-glass reflector of the Paris
Observatory. Using the 9.6"
refractor at Rome, Father Secchi claimed "even in our telescope it is easy
to recognize the spiral and the two branches can be followed very well."
(he often compared his telescopic views favorably with LdR's and Lassell's).
A bitter debate
between Wilhelm Tempel and Dreyer began in 1878 after Tempel was highly
critical of Lord Rosse's and William Lassell's sketches of spiral
structure. Tempel had only
observed M51 through the 11" refractor at Arcetri, and although he
sketched curving arcs in the halo, he felt Rosse and others were interpretating
these features as spiral forms. He
wrote "once cannot fend off the thought that these forms and shapes are
only fignments of the imagination...". Isaac Roberts obtained the first photograph of M51 on 29 Apr
1889, ending the debate.
As far as the
origin of the nickname "Whirlpool Galaxy", Ormsby Mitchel's November
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
work..."

(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 (referred to as the "crown") 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 Méchain
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."

"Keenan's System" derives from a 1935 paper "An Unusual Pair of

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

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"

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.

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

(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.

(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
the mag 15.3 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.

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.

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,

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

William Herschel
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.

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.

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 that 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.

an "arm" that interacts with NGC 5394). Several faint stars are near including a mag 13.5 1.7' S of

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

~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 and the "knot" is an off-center dwarf satellite with triggered
star formation.

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

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

hazy due to the background glow of the outer halo. After a more careful view, I noticed an extremely faint knot

(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 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.

(4/24/82): fairly bright, very large, round, about 20' diameter, bright

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 Méchain
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

R.J. Mitchell
discovered NGC 5472 on 29 Mar 1856 with LdR's 72" during an observation of
NGC 5468. He noted "about 4'

Wilhelm Tempel observed NGC 5468 in 1882 and also noted NGC 5472 as 5'
following. He mentioned it was
probably the one seen earlier by LdR.
In addition Tempel mentioned two other nearby objects (NGC 5465 and
5467) to the southwest, which are either nonexistent or single stars. See Corwin's notes.

~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

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

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.

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.

vsmbM to a *; vF at the borders."
He published a sketch in his 1811 paper (Fig. 25) as an illlustration of
"nebulae that are suddenly much brighter in the middle."
A total of 11
observations were made at Birr Castle. On 26 Apr 1848, Lord Rosse, or assistant
William Rambaut, logged "Nucleus manifested a decidedly spiral
arrangement; the neb becomes eF towards the edges; from the upper [sff] par of
the nucleus proceeds a circular spiral, only seen by glimpses (as also
spirality of nucleus)." The observation was made during the period when
spiral structure was sometimes overzealously described. NGC 5557 was
included in the list of "Spiral or curvilinear" in LdR's 1850 PT
paper, though it is a standard E-type galaxy and the 1861 publication mentions
"frequently observed, nothing certain”.

probably identical to NGC 5563.
But Harold Corwin notes that Swift's description applies to NGC 5554
(discovered earlier by Marth), as
a star is midway between the two galaxies. NGC 5565 was placed just 30" south of NGC 5564, but
there is nothing at this position. RNGC classifies NGC 5564 as nonexistent.

Lewis Swift
discovered NGC 5565 = Sw I-34, along with NGC 5558 and 5564, on 14 Jun 1884 and

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

William Herschel

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

free of nebulosity." It was
also announced in AN 108, p.369 with a position measured by Oliver Wendell at

that the nebula was "examined by, among others, Mr. Tempel and is here
inserted merely as a matter of record", but there is not published

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.
JH described NGC
5593 as "a poor, coarse, oblong cluster, which is the most condensed part
of a rich region of stars 10m. Place of a double star [HJ 4675] in the

(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

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.

The "small
patch of stars which appears almost like this nebula" in WH's description
applies to IC 4470, situated 4' west-northwest, which was rediscovered by
Bigourdan on 11 Jul 1887.
Interestingly, Bigourdan also calls it a star cluster: "Object
which, at first sight, could be nebulous, but in which I suspect several
stellar points. It is therefore a
cluster enveloped in nebulosity; it is vaguely elongated at 90 degrees and is
1' l and 40" wide."
Corwin and Steinicke both agree that WH should be credited with the
discovery of IC 4470, although it did not receive a NGC designation.

of RA (only 1.6' at this declination), but his comment "forms a triangle

vicinity of H's object and questioned if it was identical. It is, but WH's position was 1 min of
time too far west and Dreyer assumed the two observations referred to different
nebulae. So, NGC 5819 = NGC

E.E. Barnard
discovered NGC 5824 in 1882 with his 5-inch refractor in Nashville. In AN
2756, he gave an accurate micrometric position and mentions "this nebula
is recorded in GC 4036 [= NGC 5834] as eeF? I have frequently seen it
since 1882. Presuming that the nebula observed by me is identical with GC
4036, the place in GC, as well as the description is erroneous." In
Sidereal Messenger, vol. 5, p.255, he also gave a corrected position and
described this globular (through the 6" Cooke refractor) as "B; S; R;
vvmbM; probably a stellar nucleus."
Despite
Barnard's corrected position and description, Dreyer entered both Barnard's and
JH's position in the NGC. But Barnard's assumptions were likely correct
and NGC 5824 = NGC 5834, with the primary designation NGC 5824 (due to the
unambiguous position). In the IC 1 Notes and Corrections, Dreyer comments

various magnifying powers. This

and the nebulosity surrounding the bright point has not that softness which
nebulae in general possess. I
consider this different from nebulae in general." Dunlop's position was off by nearly 30'

This object is
listed in the PK and ESO-Strausberg catalogues as He 2-119 instead of NGC 5844
although John Herschel's position (from two observations) matches this
planetary. Also, it was listed as
an unverified southern object in the RNGC and probably because of this error
was not included in Sky Atlas 2000.0, Sky Catalogue 2000.0 or the first edition
of the Uranometria 2000!
John Herschel
discovered NGC 5844 = h3591 on 2 May 1835 and recorded "pB; R; vgvlbM;
60"." His position on
two sweeps is accurate. DeLisle
Stewart called it "Three very faint nebulae only" (repeated in the
IC2 Notes section).
This PN is
listed in the PK and ESO-Strausberg catalogues as He 2-119 but the identification
with NGC 5844 was only made recently!
RNGC classifies it an unverified southern object and it is not included
in Sky Atlas 2000.0, Sky Catalogue 2000.0 and first edition of the Uranometria
2000.0!

William Herschel
discovered NGC 5846 = H I-128 = h1901, along with NGC 5845, on 24 Feb 1786
(sweep 532) and recorded "vB, pL, bM. With one preceding [NGC 5845] just
[at edge of field]; and 5' more north, and vF, R. I saw also a third small one preceding." The "third small one
preceding" might refer to NGC 5839, which has a separate log entry or
Wolfgang Steinicke suggests it might apply to NGC 5846A, the very close
companion on its south side. On 13
Apr 1838, JH logged "B; R; psbM to nucleus; 30"."
But JH's first
observations of NGC 5846 was on 29 May 1821, while being instructed on sweeping
techniques by his father. His Aunt
Caroline recorded the observation: "F; R; gmbM; r; appears to have 2
nuclei; south following in the same field is a very small, round
nebula." The second nuclei is
most likely NGC 5846A. So, this is
a pre-NGC observation of the companion.
He also observed NGC 5846 the next night and just noted "The neb of
last night with the 2 nuclei."
James South also took a look and exclaimed (logged in JH's journal),
"O! Good God! It is worth
going to the devil for! Mr.
South's observation."
Guillaume Bigourdan also resolved the companion and noted Big. II-75 as
"round, stellar centre, forms a very close companion to 4045 G.C. [NGC
5846]."
In addition,
Edward Burton, observing with LdR's 72" on 25 Apr 1868, logged "h1901
[NGC 5846] is double, 3rd Nucleus suspected on n side." The third nucleus is a faint star. On 3 May 1877 Dreyer also noted
"companion nebula [to NGC 5846] vS, less than 1' south." But the following year he commented
"small star (NOT a nebula) involved south." This was likely the reason Dreyer did not enter NGC 5846A
into the NGC. DeVaucouleurs introduced the NGC 5846A designation in the RC I.

it 'blinks' with the star behind the wire." As JH suspected, this star is free of nebulosity.

William Herschel
discovered NGC 5866 = H I-215 = h1909 on 5 May 1788 (sweep 842) and recorded
"vB, cL, E, following 2 stars."
His position is poor - nearly 6' southwest of the galaxy. NGC 5866 is likely an edge-on S0 galaxy
with a dust lane. The dust lane
was prominently shown on LdR's sketch on 27 Apr 1848 and included in the 1850
"Observations of the Nebulae".
This galaxy is
sometimes taken as M102 for completeness of the Messier catalogue. Pierre Méchain found M102 on 27 Mar
1781, but it was later claimed that M102 was a duplicate of M101 and there has been
much written on this topic.
Michael Covington argues in the Sept 2015 issue of Sky & Tel that
Mechain probably did see NGC 5866, along with the adjacent 7th-magnute star and
Messier may have confirmed the observation. See Harold Corwin's notes (he concludes M102 is almost
certainly a duplicate of M101).

repeatable, though, and confirmed in excellent conditions at Lassen Peak lot.

this low surface brightness globular was easily picked up 12.5x in the 80mm
finder as a small, faint, hazy knot.
Excellent view at 225x in the 18" with 60-70 stars resolved and a
very weak concentration and no distinct core. At 325x, 90-100 stars were resolved over an 11' diameter
though the halo does not have a well defined edge so the count is somewhat
arbitrary. The hazy background
glow of unresolved star is quite lively and irregular in surface brightness.

William Herschel
discovered NGC 5897 = H VI-19 = H VI-8 = h3596 on 25 Apr 1785 (sweep 209) and
recorded VI-8 as "a very close compressed cluster of stars, 8 or 9' in
diameter, extr rich, of an iR figure, a little E. The stars so small as hardly to be visible so accumulated in
the middle as to look nebulous."
There is nothing at his position, but Dreyer chronicles problems in the
sweep in his 1912 "Scientific Papers of William Herschel".
Harold Corwin
has an extensive discussion and argument that H VI-8 = NGC 5897. WH rediscovered this cluster a couple
of weeks later on 10 Mar 1785 (sweep 383) and recorded VI-19 as "A
beautiful L cluster of the most minute and most compressed stars
imaginable. Different sizes and a
faint red colour perceivable."
His position on this sweep was only 3' south of center.

Gottfried and

husband found by this with just this 3 Sch. tube, high over Mu [Serpentis] a
nebulous light, it had many other fine stars around it, but one stood
particularly by the tube above it about thus: [sketch follows]." Charles Messier made an
independent discovery on 23 May 1764.
WH's first
observation using his 6.2-inch (7-ft telescope) was on 4 Mar 1783: "It
consists of stars; they are however so small that I can but just perceive some,
and suspect others. 1810 (power?), the globular figure is visible." On 5 May 1785 (sweep 409) he recorded,
"a very compressed very beautiful, and large cluster of small stars of
various sizes, and of a red colour.
For about 2 or 2.5' they are extremely compressed in the center; and the
pretty regularly scattered stars extend to about 7 or 8' diam." Then there are besides many more
irregularly scattered at a greater distance; especially one branch, which
extends in a direction of about 15 or 20 degrees sp and some of the stars of
this branch are rather larger than the rest." On 24 Feb 1787, he logged "The most beautiful,
extremely compressed cl of small stars; the greatest part of them gathered
together into one brilliant nucleus; evidently consisting of stars, surrounded
with many detached gathering stars of the same size and colour."

found NGC 5923 = h1921 on 6 May 1828 and logged "F; pL; lE;
vgbM." JH made a total of 4
observations (including sweep 151), with size estimates of 40" and
60". Because of his father's
poor position for NGC 5922 = H III-661, he assumed his observation was new and
reported it as a "Nova".
So, NGC 5922 = NGC 5923. By
historical precedence, the primary designation should be NGC 5922, but this
galaxy is known as NGC 5923 due to the unambiguous position.
On sweep 151, he
also made an observation of what he assumed was H III-661 at ~4' south of the
NGC 5923. Close to this position
is a 17" pair of 16 mag stars.
This is perhaps what JH took for H III-661, though there is no

number. See Corwin's

discovered NGC 5925 = h3603 on 28 Jul 1826 and recorded "a most numerous

diameter (20' or 30') entirely composed of double and triple stars, and
distinct groups of 4 or 5 nearly of a size (10th and 11th mag) on a black

chiefly 11, 12 and 13th mag, sufficiently insulated from the rest of the pretty
rich neighbourhood to be considered a cluster."

James Dunlop with the discovery (D 357), but Dunlop's position is a much better

the strong impression that it was on the verge of more extensive

18" (7/6/05
- Magellan Observatory, Australia): at 128x this globular appeared moderately
bright, moderately large, round.
The halo extends to 3' diameter with averted vision and surrounds a
brighter 1' core. At 228x a number
of very faint stars are just resolved around the periphery of the halo in
moments of better seeing with perhaps two dozen stars resolved in total
including a bright mag 12 star (superimposed field star?). Many of the resolved stars form a
semi-circular loop, ringing the halo along the entire eastern half of the
globular. Several mag 10-11 stars
form a long chain curving around from the SW to the east side, ~5' from the
cluster. Situated within a
beautiful Norma star field ~70' E of NGC 5927.
8" (7/13/91
- Southern Baja): faint, very small, 1.5' diameter, round, almost even surface
brightness with a weak concentration.
A mag 12 star is at the WSW edge (field star). The core appears displaced towards this star. No additional resolution was
evident. Located in a rich star
field with globular cluster NGC 5927 70' W. Viewed at about 14° elevation from Baja.
John Herschel
discovered NGC 5946 = h3607 on 8 May 1826 and recorded "not vB; S; glbM;
90"; resolved into stars 16m, with one of 12m, at or a little beyond the
sp edge." His position (mean
of two observations) is accurate.
Harold Corwin
notes that James Dunlop may have been the first to discover this globular. Glen
Cozens, who examined a copy of Dunlop's original observing log, found about a
dozen objects that did not make it into Dunlop's published list and NGC 5946 is
probably one of them. Lewis Swift
independently found this globular on 24 May 1898 and reported list XI-180 as
"pB; pS; lE." His
position is 42 sec of time too far west, but as Harold Corwin notes, there are
no other possible nearby candidates.
This was his most southerly observation from California and one of his
very last. So NGC 5946 = IC 4550. See Corwin's identification notes for
more.

d'Arrest measured an accurate position as well as the mag 10 star that precedes

The UGC PA = 165° is incorrect and the error is repeated in the RC3 and

(5/15/12): NGC 5996 is the brighter member of an interacting pair (Arp 72) with
NGC 5994. At 488x it appeared
quite bright, elongated over 2:1 SSW-NNE, though the brightest central section
(bar) is elongated ~E-W. The
galaxy is well concentrated with a very bright, elongated core or bar. It has an asymmetric appearance with a
long, bright arm attached on the east side. This arm hooks southwest towards NGC 5994 and appears
slightly clumpy (a knot in the arm is 24" S of the center). On the west end of the bar a shorter
arm shoots straight north and fades quickly as it starts to hook east, with the
brightest portion near the connection with the bar.

fully resolved and too poor to be a true cluster.
William Herschel
discovered NGC 5998 = H VII-29 on 30 Apr 1786 (sweep 559) and recorded "A
small cl of vS stars, pretty rich; coming just from the light, I saw it
imperfectly, about 5 or 6' long and near 4' broad, in the form of a
parallelogram. Five minutes after
it was past, I returned to it, and saw it very well."
At his position
is group of stars that Dave Riddle called a "detached scatter of nine 13th
to 14th magnitude stars in a loose arrangement spanning about 3' across. The immediate field appeared bland,
making this cluster (asterism?) obvious." ESO and RNGC both report the object as not found. See Harold Corwin's identification
notes.

- Magellan Observatory, Australia): at 229x, this is a fairly rich, moderately
large cluster. In the center is a
striking elliptical ring of roughly two dozen stars. Surrounding this annulus is a larger loop of stars forming a
heart-shaped asterism. The looping
star patterns make this an interesting visual target! The diameter is roughly 8', though with no distinct border.
James Dunlop
discovered NGC 5999 = D 343 = h3612 on 8 May 1826 and described "a pretty
large faint nebula, with several minute stars in it; round figure, 4' or 5'
diameter, resolvable." His
position was off by ~10' west-southwest.
JH made a single observation on 9 Jul 1834 and reported "cluster VI
class. A pretty rich large cluster, round; little compressed in the middle,
12', stars 12..14th mag, nearly fills field; middle taken."
