Description: The two bright galaxies are NGC 4921 and NGC 4911.
NGC 4911 (12.7m (v), 1,5'x1,3', SAB(r)bc, Br4): Round, quite
strongly concentrated. A very faint nucleus suspected. Diam.
about 50''. 

NGC 4921 (12.1m(v), 2,5'x2,2', SB(rs)ab, Br4): In the center of
the field. Lower surface brightness than -11 but total
brightness higher. Moderately concentrated, round.

NGC 4919 (14.1m(v), 1.1'x0.7', SA(r)0:, Br5): Extremely faint
and stellar. 4.5' S of NGC 4921. 

NGC 4923 (13.7m(v), 0.8'x0.8', SA/r)0-?, Br5): Barely non-
stellar, very small. A bright core faintly visible. 2' SE from
NGC 4921.
