Albert Marth discovered NGC 2923 = m 171 on 1 Apr 1864 and simply noted "vF". His position is 2' N of CGCG 092-008 = PGC 27306, so this identification is pretty secure.

400/500mm - 17.5" (4/6/02): extremely faint, very small, round, 20" diameter. Required averted to glimpse intermittently once exact position identified. Located at the western edge of a faint group of galaxies (brightest member NGC 2943).

600/800mm - 24" (3/21/20): at 260x, very faint, very small, round, 24" diameter, low even surface brightness. The CGCG blue photographic mag of 15.2 is too bright -- this galaxy is quite faint.
