This bright trio is situated within the square of Pegasus, 1°
NNW of 5.1-magnitude Phi Peg. At 260x, NGC 7769 = KTG 82A appeared
bright, fairly large, round, 1.6' diameter, sharply concentrated with
a very bright core and stellar nucleus. The low surface brightness
outer halo (spiral arms) is slightly elongated and gradually fades
out. NGC 7769 is the brightest component of KTG 82 with NGC 7770 and
7771 (1' pair) both 4.5' SE. NGC 7771 also appeared bright, fairly
large, very elongated 3:1 WSW-ENE, 2.0'x0.7', moderate concentration
with a large, elongated core that gradually increases to the center.
Forms a 1.1' pair with NGC 7770 = KTG 82B. This is the smallest member
and appeared moderately bright, fairly small, elongated 5:3 SSW-NNE,
0.5'x0.3', with a small bright core.

This triplet consists of the contact pair NGC 274/275 = Arp 140 =
VV 81, along with NGC 273 11' NW. At 75x, the brightest member NGC
274 = KTS 7B appeared bright, round, fairly small, 0.6' diameter,
sharply concentrated with a small intensely bright core that gradually
increases to the center, but no nucleus. This is the brighter but
smaller component of a striking double system with NGC 275 = KTS 7C,
which is attached on the SE side. NGC 275 appeared moderately to fairly
bright, elongated 5:3 NW-SE, ~45"x27". Very unusual patchy,
irregular appearance! A brighter elongated N-S patch (or arm) is on
the east end. Also the southwest border is slightly brighter with
a sharp, curving edge. This edge is more prominent at the NW end of
the galaxy, where it merges with NGC 274 just northwest. Finally,
NGC 273 = KTS 7A is moderately bright and large, very elongated 3:1
WNW-ESE, ~48"x16". Contains a very small brighter core.
A mag 14 star is off the NW edge by ~20".
NGC 283 Group
00 53 13.2 -13 09 50
This galaxy group is located 2° SE of the planetary NGC 246 in Cetus.
NGC 283 is the first and largest of five galaxies consisting of four
similar NGCs and much fainter MCG -02-03-03, squeezed into a 5' circle.
At 375x NGC 283 appeared fairly faint, moderately large, elongated 4:3
NNW-SSE, 0.4'x0.3', weak concentration. A mag 13.5 star lies 1.6' NE.
NGC 284 and 285 follow directly east by 2.7' and 4.1' with NGC 286 5.2'
NE and much fainter PGC 173072 is 1.9' NNE. NGC 284 is fairly faint,
small, slightly elongated N-S, 20"x15". A mag 13.5 star lies
1.6' NW. Continuing on a line to the east, NGC 285 is fairly faint,
small, slightly elongated N-S, 18"x15", very small brighter
nucleus. NGC 286, 3' due N, appeared fairly faint, fairly small, oval
4:3 N-S, 40"x30", weak concentration, small brighter nucleus.
By a slight margin, this galaxy has the highest surface brightness in
the group. Finally, PGC 173072 (misidentified as MCG -2-03-032) was
an extremely faint and small glow, ~10" diameter, and required
00 57 40 +43 45 06
KTG 2A = NGC 317A and KTG 2B = NGC 317B form a contact pair oriented
NNW-SSE, just 35" between centers. At 375x, KTG 2A appeared fairly
faint to moderately bright, small, fairly high surface brightness (core
region) ~15". With averted vision, the core is surrounded by a
thin, very low surface brightness halo increasing the diameter to 25".
KTG 2B appeared fairly faint, very elongated WNW-ESE, ~45"x15",
weak concentration, slightly brighter core. Two mag 11.5/13.8 stars
lie 1' W. A group of mag 10-13 stars is roughly 4' S and CGCG 536-014
= KTG 2C lies 6' S, beyond this asterism and appeared faint, fairly
small, elongated 3:2 WSW-ENE, 25"x18", low even surface brightness.
STF 79, a nice 8" pair of mag 6.0/6.8 stars lies 1° NE.
IC 1623 = Arp 236 = VV 11 = ESO 541-IG23
01 07 47.2 -17 30 25
Arp 236 = VV 114 is in the Arp category of "appearance of fission",
though this contact pair is apparently undergoing a merger and the two
nuclei are separated by only 15"! IC 1623A, the brighter western
component, appeared fairly bright, fairly small, round, 25" diameter,
high surface brightness. IC 1634B, attached on the east end, appeared
as a fairly faint, small glow that not separately resolved, just a bulge
or knot on the east end. 365x revealed a broad concentration with a
brighter nucleus. Research reveals the IC 1634B is optically obscured
but very bright in the infrared indicating intense star formation. IC
1622 lies 3.1' SW and appeared fairly faint, fairly small, round, 25"
diameter. 365x revealed a broad concentration with a brighter nucleus.
This image is a close-up of the system from the HST.
01 08 27 +33 07 42
This small, physical triplet (spans only 2.7') contains three NGC galaxies;
NGC 392 = KTG 3A, NGC 394 = KTG 3B and NGC 397 = KTG 3C. NGC 393, the
brightest member appeared fairly bright, fairly small, slightly elongated
SW-NE, 30"x25", increases to a bright stellar nucleus. A mag
13 star lies 1.2' SW. Forms a close pair with NGC 394 1.0' NNE. At 375x
it was moderately bright, fairly small, elongated 2:1 NW-SE, 0.4'x0.2',
with a small brighter core. Lastly, NGC 397 was fairly faint, small,
15"x12", slightly elongated SW-NE, very weak concentration.
Also in the immediate vicinity is IC 1619, 13' WSW and UGC 692 15' SW.
Arp 11 = VV 348
01 09 22.0 +14 20 32
V = 13.6; Size 1.5'x0.7'; Surf Br = 13.5; PA = 162d
UGC 717 = Arp 11 (category "Spiral Galaxies: split arm") is
the brightest in a small triplet. At 375x it appeared fairly faint,
fairly small, round, 35", even surface brightness. This description
appears to apply to the core region and the low surface brightness arms
were not noticed. Forms a close pair with much fainter MCG +02-04-004
1.1' SE, though the companion is apparently in the background at 800
million l.y. A mag 12 star lies 2.3' WSW. MCG +02-04-004 appeared faint,
very small, round, 10" diameter. UGC 719, just 2.1' NE, completes
a nice compact triplet. I logged it as faint to fairly faint, small,
slightly elongated ~N-S, ~24"x20", very weak concentration.
The distance of this galaxy and UGC 719 is roughly 500 million light
Arp 119 = VV 347
01 19 24.6 +12 27 43
V = 13.9 and14.1; Size 0.8'x0.5' and 1.2'x0.6'
Arp 119N = VV 347b is the slightly brighter (higher surface brightness)
of a close pair with disrupted Arp 119S = UGC 849. At 375x, the northern
component appeared fairly faint, small, elongated 4:3 N-S, ~20"x15",
very weak concentration.
Arp 119S = VV 347a, a highly disturbed galaxy just 0.9' S, appeared
fairly faint, small, slightly elongated ~E-W, ~25"x20" (central
region only seen). Located 4.5' NNW of a mag 9.6 star. PGC 1410939 lies
6' NW and was logged as extremely faint and small, round, 10" diameter.
On the SDSS image, UGC 849 is strongly disturbed with an unusual asymmetry.
It features an offset nucleus on the north side, a spike or filament
extending north towards CGCG 436-023 and numerous blue, thin knotty
"sprays" or arcs with extensive star formation.
01 20 35 -17 22 30
KTS 9C = ESO 542-6 is the brightest member of this triplet. At 225x
it appeared fairly faint to moderately bright, fairly small, irregularly
round, ~25"x20" diameter, high surface brightness. KTS 9B
= ESO 542-7 and KTS 9A = ESO 542-8 form a close pair of faint edge-on
galaxies just 3' S. KTS 9B is slightly brighter than its partner though
still appeared faint, fairly small, very elongated 4:1 E-W, ~0.4'x0.1'.
KTS 9A is barely off the south side (30" between centers) and appeared
very faint to faint, fairly small, very elongated 7:2 NW-SE, 21"x6".
A small triangle with 1' sides consisting of mag 12.4/13.4/14.8 stars
is just preceding the close pair.
NGC 7678 = Arp 28 = VV 359
23 28 27.9 +22 25 16
V = 11.8; Size 2.3'x1.7'; Surf Br = 13.2; PA = 5d
NGC 7678 is in the Arp group of "spiral galaxies - one heavy arm",
which is evident visually. At 260 the galaxy is beautifully framed with
a thin triangle of mag 11.3/11.4 stars to the north and a mag 12 star
off the south end. It appeared fairly bright, moderately large, elongated
SW-NE, ~1.8'x1.3'. Contains a brighter elongated core that increases
to a very small brighter nucleus. The "heavy arm" is visible
on the south side as a thin, shallow arc in the outer halo and brightens
(HII knot?) right at its western tip.
Pegasus Dwarf = Andromeda VI = UGC 12613 = MCG +02-59-046 = CGCG 431-072
23 28 34.1 +14 44 48
V = 12.6; Size 5.0'x2.7'; Surf Br = 15.3; PA = 120d
The Pegasus Dwarf was picked up at 200x as a faint, large, very diffuse
elongated glow with a couple of stars superimposed. This Local Group
galaxy dwarf appeared roughly 4.0'x2.0', extended WNW-ESE. The surface
brightness is quite low and fairly even except for a slightly brighter
30" patch (core?) near the center. A mag 14 is just within the
ESE end (the patch is ~1' WNW of this star) and a brighter mag 12.7
star is embedded on the south side of WNW end.
