22” f/4.1 (203, 293, 377 and 528x) — Four
galaxies were immediately seen arranged like an L”. UGC
10053 appeared as a considerably faint round smudge with
a slightly brighter center. It is about 45” across. A 15th
magnitude double star lies about 1 WSW from the core. A
blinding 7.5 magnitude star lies 4.5 due west and must be
kept off the field. This galaxy marks the top of the L”.
MCG+12-15-18 shows a considerably faint, round smudge with
a slightly brighter center. It is about the same size and
brightness as UGC 10053, which lies 1.2 WNW. MCG+12-15-20
— Considerably faint, 3:1 elongated even surface brightness
patch. It is about 45” long with a position angle of 170
. An 11.1 magnitude star lies 38” SSW. This galaxy marks
the corner of the L”. MCG+12-15-18 lies 3.5 WNW and IC 1146
lies 3.8 SSW. IC 1146 is a considerably bright round patch
with a stellar nucleus. This galaxy is about 90” across
and lies on the end of the short arm of the L”. A nice 13th
and 15th magnitude double star lies 2.2 north. - Alvin Huey |

very elongated 3:1 E-W, 0.6'x0.2', with a low even surface
brightness. Located 2.5' NW of a mag 13 star. Forms a close
pair wth HCG 78B = MCG +11-19-016 just 1.2' SW. This faint
member of HCG 78 appeared extremely small and round at first
glance. In fact, all that I noticed initially was the fairly
bright substellar nucleus, ~6" in diameter but with averted
vision, small thin extensions were occasionally visible
extending the size to 0.6'x0.2'. Although both galaxies
are edge-ons, 78A has a low even surface brightness while
78B is sharply concentrated with extremely faint arms. |

18" HCG 80A = CGCG 319-038 is the brightest
in a tight trio. At 223x, it appeared faint, small, very
elongated 3:1 WSW-ENE, 0.6'x0.2', with a low even surface
brightness. Collinear with a 30" pair of mag 14 stars about
2' S. HCG 80C is found 1.2' to the west and appeared extremely
faint and small, round, just 6" diameter. The "C" component
was noticed before "B" which required more effort to view.
HCG 80B, a mere 30" to the south of HCG 80A was only glimpsed
on several occasions as an extremely faint, extremely small
knot, ~6" diameter. Back in '96, I could could almost hold
this galaxy steadily with averted vision. Must by gettin'

18" HCG 75A was missed by the great visual
observers of the 19th century and first picked up from the
Palomar Observatory Sky Survey plates in the early 1960's.
CGCG 135-050 appeared faint, small, roundish though with
an irregular outline, 20" diameter. Occasionally, a very
faint stellar nucleus was visible with direct vision. Located
1' SW of a mag 12 star. This is a double system (with HCG
75B), although the companion was not seen with confidence.
HCG 75C, situated 2' SE, appeared as a mag 15.5 star with
no detectable size (only the stellar nucleus seen). It required
averted to see this member clearly but the observation was
easily repeatable. HCG 75D is a mere 26" NW and was only
intermittently glimpsed as an extremely difficult, virutally
stellar knot on line with 75C and the mag 12 star close
north of the group. |

18" Seyfert's Sextet is arguably the quintessential
Hickson group. Five or six galaxies crammed into a couple
of arc minutes. I've returned to this object many times
over the past 20 years and always resolve the three brightest
components (a 4th component was barely visible in a 30-inch
Starmaster last summer). HCG 79B is the brightest component
of Seyfert's Sextet and at 257x appeared faint, very small,
slightly elongated ~E-W, 15"x10", containing a faint stellar
nucleus with direct vision. A mag 14.5 star lies 1' ESE
and two additional mag 14.5 stars lie close SE. HCG 79C
lies just 22" west of center and is the faintest in the
resolved clump of three. It appeared extremely faint, round,
8"-10" diameter. Close south of this pair is HCG 79A, another
small knot that appeared very faint, slightly elongated,
15"x10". To give credit where it's due, Seyfert's Sextet
was actually discovered by Edouard Stephan in 1882. Carl
Seyfert's name was later attached after a paper he authored
in 1951 revealed this knot contained five or six galaxies
crammed into a space smaller than our Milky Way. Although
Stephan recorded this ultra-compact group as only a single
object, his description "eF, vF* inv, 2 vF st nr" implies
to me that he probably resolved three members though he
mistook two of the nearly stellar galaxies for stars. |

17.5" (7/7/94): forms the NE member of a striking
double system with N5953 attached at the SW side. Fairly
faint, fairly small, very elongated 3:1 N-S, 1.0'x0.3'.
Almost even surface brightness but possibly brighter on
the south end (photograph shows the core asymmetrically
placed on the south end). Preceded by a string of three
mag 13 stars which are 4' W and a pair of mag 13 stars with
1' separation is 1.5' SE. A mag 10 star lies 6' S. |

halo slightly elongated ~E-W. A mag 15-15.5 star is just
visible at the SW edge 23" from the center. Forms a striking

20" - Palomar 14's location is exactly as
on MegaStar chart. Easy to locate as a bright star is close
by. Not nearly as difficult visually as Pal 15. Though its
listed mag is fainter, Pal 14 has a higher surface brightness
than Pal 15. Seen as a diffuse soft round glow, with no
brightening to its middle, and no hint of any resolution.
But the edges of the globular are fairly strong against
background sky. According to Skiff, brightest stars are
17.6 mag and horizontal branch magnitude of stars in the
cluster is 20.06 One of most distant globulars from the
Sun. Discovered by H. Arp. - Barbara Wilson. |

18" At 257x an extremely faint, small, low
surface brightness glow was intermittently visible perhaps
1/3 of the time. Forms the southern vertex of an equilateral
triangle with two mag 12.5 to the ENE and NNW. Only a single
member or the combined glow of two or more members was seen.
A few years back HCG 81 appeared elongated or possibly double,
although I still was not able to resolve the glow clearly
into separate components |

18" While surveying the NGC, I previously
had run across NGC 5919 and 5920 which are outlying members
of the rich cluster, Abell 2063. Within the main portion
of the cluster, the new version of the Uranometria simply
plots one galaxy, MCG +02-39-020. Although this Serpens
galaxy cluster was slipping into the western sky when I
started observing, I was pretty amazed to identify 21 new
galaxies in the cluster -- mostly in the same high power
field!! These galaxies are generally in the mag 15.5-15.7
(B) range and sometimes required 300x to distinguish from
faint stars. As you might guess, there wasn't much detail
in these 10"-15" blobs -- just logging and identifying them
was an accomplishment. |

17.5": fairly faint, fairly small, gradually
increases to a bright core, mottled appearance. A knot is
visible on the W side (there is a brighter extension on
the SW side on the POSS). A mag 15 star is 1.1' S of center
and an extremely faint mag 16 star is just off the NNW end. |

NGC 5942 |

17.5" This rectangular quartet consists of
three NGC galaxies, although NGC 5941 and NGC 5942 (discovered
by Lewis Swift) have been misidentified in nearly all modern
catalogues. I felt the brightest member visually was NGC
5941 ("B") which appeared faint, fairly small, elongated
4:3 SW-NE, 0.7'x0.5', weak concentration to a brighter core,
faint stellar nucleus. NGC 5944 ("A") situated 2.6' SE is
very faint, round, 30" diameter, weak concentration with
a slightly brighter core. NGC 5942 ("C") is very faint,
very small, round, 20" diameter with a stellar nucleus at
moments. A mag 14.5 star is off the NW side 45" from center.
This is the third brightest in the group. The faintest member
MCG +01-40-002 ("D") is 2.0' SE and appears extremely faint,
very small, 15" diameter, low even surface brightness. A
mag 15 star is 1.1' SE. |

18" (7/26/06): at 435x the cluster overfills
the field and the intense 3.5' core is resolved to the center.
The core has two easily resolved parallel star lanes oriented
E-W that cross the core on the north and south sides and
an extremely dense knot of stars is resolved on the west
side of the northern lane. M5 was just visible naked-eye
but the nearby mag 5 star (5 Ser) detracts from the observation. |

18" (7/24/06): at 325x appears bright, fairly
large, round, pretty symmetrical appearance, contains a
blazing 1.5' core in a 5' to 6' halo. At 435x the halo and
the periphery of the core are well resolved into roughly
100 stars and additional extremely faint stars pop in and
out of visibility. The core itself is overlayed with a number
of faint stars. Beautiful view at 565x as the cluster nearly
fills the 7' field with stars from edge to edge with 100-150
stars and the core region is well resolved. The cluster
appears asymmetric with the halo more extensive to the west
(core offset to the east). |
