Notes: NGC 5846 is the centerpiece (brightest) of this group, but NGC 5850 is the most interesting photographically ... from west to east (right to left) are NGC 5839, NGC 5845, NGC 5846 and NGC 5850. My software (Megastar v5.0.12) lists the little galaxy just under the core of NGC 5846 as NGC 5846A = PGC 53930 = MCG+0-38-26 (0.4'x0.3', 13.8 mag, Cl: cE2-3).

Contemporary Visual Observation(s) for NGC 5846
NGC 5846 = UGC 09706 = MCG +00-38-025 = CGCG 020-061 = Ho 694a = LGG 393-003 = 
PGC 53932
15 06 29.3 +01 36 25
V = 10.0;  Size 4.1x3.8;  SB = 13.0

17.5": bright, moderately large, oval 3:2 NNW-SSE, 3'x2', evenly concentrated as 
halo brightens down to a small bright core but no nucleus, fainter halo.  Forms 
a contact pair with N5846A (appears as a mag 13.5 "star") embedded in the 
southern portion of halo 40" from the center!  Brightest in a group with N5850 
10' ESE and N5845 8' WNW.

V = 12.7;  Size 1.3x1.2;  SB = 13.0;  PA = 35d

17.5": fairly faint, fairly small, round, moderate concentration down to a small 
bright core containing a substellar nucleus.  Member of the N5846 group with 
N5845 10' E.

Contemporary Visual Observation(s) for NGC 5845

NGC 5845 = UGC 09700 = MCG +00-38-024 = CGCG 020-059 = LGG 392-006 = PGC 53901
15 06 00.8 +01 38 01
V = 12.5;  Size 0.8x0.5;  SB = 11.5;  PA = 150d

17.5": fairly faint, extremely small, round, very small very bright core, 
extremely compact, about 20" diameter.  Appears like the bright nucleus of a 
galaxy without a halo.  Member of the N5846 group with N5846 8' ESE and N5839 
10' W.

Contemporary Visual Observation(s) for NGC 5850
NGC 5850 = UGC 09715 = MCG +00-39-002 = CGCG 021-006 = PGC 53979
15 07 07.8 +01 32 47
V = 10.8;  Size 4.3x3.7;  SB = 13.6;  PA = 140d

17.5": fairly faint, moderately large, slightly elongated.  Unusual appearance 
as the large bright core dominates the galaxy but there are very faint larger 
extensions (either a bar or arms) very elongated 3:1 WNW-ESE clearly seen with 
averted.  There is a very large difference between the surface brightness of the 
core and these extensions!  Two mag 12 stars lie 2' N.  A mag 11 star 5.5' NW is 
midway between N5850 and N5846 which lies 10' WNW.
