Hickson 39 in Hydra 09 29

20 51 48”
(610x)
– Chain of four equally spaced galaxies aligned NW to SE
and 1.2’ long.
Component A, B and C are equal in brightness and
size and in a perfect collinear line. Component D is
slightly brighter than the first three and slightly
north of the line formed by A to C. Stellar cores
in all components except C. An extra
nearby galaxy, PGC 1120300, is an even surface
brightness 3:1 elongated glow with somewhat diffuse
edges. 0.2’
long and PA = 90 degrees. |

Hickson 50 in Ursa Major 11 17
06 +54
55 01 48”
(488
and 610x) – The seeing wasn’t that steady while I was at
the eyepiece. I’ve
seen all five components at an earlier time with this
scope. Detected
only components A, B and D as very to extrememly faint
very small round glows.
A mag 16.7 star lies just 20” SW from component
A. |

Hickson 45 in Ursa Major 10 19 11 +59 06 29 48”
(488,
610 and 813x) – Component A
is a bright 5:2 elongated glow with diffuse edges. Much brighter
center. PA
= 80 and 0.8’ long.
A mag 12.7 star lies 1.0’ SE. A mag 13.1
star lies 0.9’ slightly west of due north. Component B
is a considerably faint even surface brightness small
round glow with a slightly brighter center. Defined edges. 0.2’ across. Component C
is a very faint 3:1 elongated even surface brightness
glow. 0.2’
long and PA = 135 degrees.
A blazing mag 11.1 star lies just 25” SW and a
mag 12.9 star lies 1.2’ ESE. Component D
is just 15” NE from the east end of Component A. A faint very
small round glow with defined edges. 0.1’ across. |

Hickson 54 in Leo 11 29 16 +20 35
04 48”
(488,
610 and 813x) – Unresolved glow with resolved individual
roughly equally spaced cores in s slightly bent string
of 0.8’ long and aligned SW to NE. The NE end is
slightly bent northwards.
The core of component A is slightly elongated of
about 0.2’ across.
The other three cores are nearly stellar to
stellar. A
bright mag 9.6 star lies 4.8’ SW. |

Hickson 55 in Draco 11 32 07 +70 48
49 48”
(488x) All
five
galaxies were well resolved in a curvy line aligned N-S.

Hickson 56 11 32

56 29 48”
(488
and 610x) – Nice
compact group of five galaxies with three members (B, C,
D) almost merged together with and edge on located on
the east end and a small elliptical on the west end. 2.3’ from end
to end. Component A
is a 5:1 considerably faint thin even surface brightness
streak. The
stellar core seen in my 22” was very difficult to
detect, popping in and out about 25% of the time at
610x. 0.7’
long and PA = 0 degrees. Component B
is a 5:2 elongated glow with a brighter small center. Defined edges. The west end
very slightly hooks to the north. PA = 60
degrees and 0.5’ long.
Almost touching component C to the west. Component C is
a fairly faint round even surface brightness glow with
defined edges. 0.5’
west from the center of component B. Component D
is similar in brightness and size with component C,
which is just 15” due east. Component E
is also similar to component C and D in size and
brightness. Lies
40” SW from component D. |

48”
(488
and 610x) – Five galaxies seen with a bonus galaxy. Component A
is a very bright round glow with a much brighter center.
Defined
edges. 0.5’
across. Component B
is a bright round glow with a brighter center. Slightly more
diffuse edges than A. 0.3’
across. A
dimmer version of A.
2.0’ WSW of component A Component C
is a 3:1 elongated even surface brightness glow with
diffuse edges and a stellar core. PA = 90
degrees and 0.6’ long.
1.8’ SE of component A Component D
is a faint amorphous slightly irregular diffuse glow. Even surface
brightness. 0.4x0.3’
and PA = 0 degrees.
0.9’ east of component A Component E
is a very faint 2:1 elongated glow with diffuse edges. PA = 45
degrees and 0.2’ long.
2.7’ NW of component A. The
bonus
galaxy is just 0.8’ NW of component B and is a very
faint round glow. 0.1’
across. |

Hickson 63 in Centarus 13
02 10 -32
46 25 48”
(488x)
– Component A
is a bright 3:1 elongated and slightly mottled glow. Defined edges. PA = 0 degrees
and 0.9’ long. Component B
is the reason why I went for this object in the 48” as I
wanted to see if I could see the single arm. Bright 2:1
elongated glow with an easily seen arm on the south. Almost stellar
core seen. No
other detail was seen. Component C
is a fairly bright round glow with somewhat diffuse
edges. 0.4’ across and 1.0’ west of component A. Component D
is a faint very small round glow located 0.9’ NW from
the core of component B. 0.1’
across. |
