Description: 13 galaxies in one field!
The bright galaxy in the center is NCG 4874 (11.6m(v), 2'x2',
E0+, Br3): Round, moderately and broadly concentrated. Size
about 1.3'. 
Two stellar galaxies are very near NGC 4874.
NGC 4871 (14.1m(v), 0.7'x0.5', SA0, Br5): Stellar, 14th
magnitude
NGC 4873 (14.0m(v), 0.8'x0.6', SA0, Br5): Slightly brighter than
-71. Stellar.

The 2nd brightest and largest is NGC 4889 (11.5m(v), 2,9'x1,9',
E4+, Br3): Almost round, quite strongly concentrated. Quite much
like -74. It has also two stellar companions:
NGC 4886 (13.8m(v), 1,1', E0, Br4): Stellar, quite easy (13.5m)
NGC 4889 (13.5m(v), -, E+, Br5): Stellar, quite easy.

Four very small galaxies are found S of NGC 4889.
The brightest and largest is NGC 4876 (14.4m(v), 0.6'x0.5', E5,
Br5): Small (15-20''), round, clearly concentrated.
NGC 4875 (14.6m(v), -, SA0, Br5): Stellar, some nebulosity
suspected. Difficult.
IC 3973 (14.4m(v), -, SB0, Br5): Stellar.
NGC 4869 (13.7m(v), 0.7'x0.7', E3, Br5): A nebulous star, the
nebulosity being very diffuse and faint. 

The last 3 galaxies W of NGC 4889. 
NGC 4867 (14.4m(v), 0.7', E3, Br5): Stellar, 14.5m. Quite
difficult. 
NGC 4864 (13.5m(v), 0.6'x0.3', E2, Br5): barely non-stellar with
averted vision. A vF, eS disk. 
IC 3955 (14.4m(v), -, SA0, Br5): Stellar. Faint.
