Arp 243 – NGC 4509 in
Cancer 08
38
24.1 +25 45
15 2.4x0.7’ 14.0b 48” (488x)
- Very nice integral signed galaxy with a very bright
3:2 elongated core.
The east arm is slightly brighter than the west
arm. The
east arm is faint and fairly diffuse and held 100% of
the time with averted vision. About 1’ long. The west arm
is slightly straighter than the other arm. The west arm
stretches about 0.8’ long.
A faint round glow appears just south of the
core. |

Arp 24 - NGC 3445 and
MCG+10-16-24 in Ursa Major 10
54
35.1 +56 59
16 1.6x1.4’ 12.9 1.0x0.3’ 15.7 48” (488x)
- NGC 3445 - A bright mottled low surface brightness
glow with diffuse edges.
The primary intent for this object with the 48”
is to see if I can observe the connector to
MCG+10-16-24, which I did as a very faint connector
which goes about 1/3 of the way to the MCG. MCG+10-16-24 –
Faint 3:1 elongated diffuse even surface brightness
glow. PA =
90 degrees and 0.4’ long.
MAC1054+5700 – Very faint 2:1 even surface
brightness glow with a bright round very compact core. PA = 60 and
0.2’ long. A
blazing mag 10.0 star lies 2.1’ NE. |

Arp 151 – MCG+9-19-73 in
Ursa Major 11
25
35.2 +54 23
15 1.1x0.3’ 16.6 48” (488x)
– MCG+9-19-73 - A thin glow with three knots, the
southern knot is by far the brightest 3:2 elongated
knot. The
middle one is a second brightest knot and is nearly
stellar. The
last, NW knot is the dimmest and is stellar. Each knot is
about 20-25” apart.
0.8’ long and PA = 150 degrees. MAC 1125+5423,
located 2’ due west is a 2:1 bright elongated glow with
somewhat diffuse edges and a much brighter round core. PA = 90 and
0.2’ long. A
blazing mag 8.7 star lies just 1’ north of Arp 151. |

Arp 270 NGC 3395 and
3396 Leo Minor 10
49
50.1 +32 58
58 1.8x1.6’ 12.0v, 4.2x1.4’ 12.6p 48” (488x)
– Two very mottled glows with quite a few large knots
and brighter centers.
A couple knots detected in the connecting arm. |

Arp 97 MCG+5-29-11
and MCG+5-29-10 in Ursa Major 12
05
44.7 +31 03
17 1.4x0.5’ 15.3, 1.6x0.5’ 15.7 48” (488x)
- Very cool coat hanger looking group of galaxies. The hook off
MCG+5-29-11 is considerably faint, but obvious. It hooks to
the west side hooking to the south. It is brighter
than the connecting streamer to MCG +5-29-10, which lies
2.4’ due north. The
two mentioned galaxies group forms a coat hanger with
MCG+5-29-12, despite that there are no bridges to
MCG+5-29-12. Very
cool object in the 48” |

Arp 148 MCG+7-23-19
and MAC 1103+4050 in Ursa Major 11
03
53.9 +40 51
00 0.5x0.3’ 15.4, 0.4x0.3’ 16.5 48” (488 and
610x) -
The penetrator is a 3:1 elongated fairly high surface
brightness glow with defined edges. The
interesting feature is that it has 3 bright knots along
the middle. The
ring galaxy is considerably faint and even surface
brightness with defined edges. |

Arp 57 MCG+3-34-12
in Coma Berenices 13
16
47.3 +14 25
40 0.9x0.6’ 14.8 48” (488x)
- MCG+3-34-12 easily shows the spiral structure with the
north arm sharply bends more than the south arm. The south arm
is connected to the companion galaxy at the tip and
doesn’t bend nearly as sharply as the north arm. The galaxy is
about 0.5’ due south of the core of MCG+3-34-12. MCG+3-34-13 is
a bright round diffuse glow and lies 1.3’ SE of
MCG+3-34-12. |

Arp 149 IC 803, MAC
1239+1635B/C/D in Coma Berenices 12
39
37.6 +16 35
18 0.5x0.2’ 15.9, 0.2x0.1’ 17.5, 0.3x0.2’ 16.5, 0.2x0.1’ 17.0 48” (488 and
610x)
- The east component (consisting of IC 803, MAC
1239+1635B, D) is
a 4:1 elongated glow with three knots. The middle one
is the brightest knot.
The lone galaxy, NAC 1239+1635C, lies 25” due
west of the middle knot and is a very bright stellar
core with a diffuse halo.
0’2 across. We didn’t see the extension to the
SW. |

Arp 274 NGC 5679B/A in
Virgo 14
35
08.8 +05 21
32 1.1x0.7’ 13.8 1.3x0.6’ 14.5 48” (488 and
610x)
- The original goal of observing this object with the
48” is to fish out the attached companion that lies
about 40” SE from the center of NGC 5679B. The companion
is a considerably faint very small round glow. |
