John Herschel discovered NGC 4122 = h1093 on 29 Apr 1827 and recorded "eF; vS; R; mbM." There is nothing near his position, though 1.1 min of RA west is CGCG 187-009 = PGC 38451. JH found the galaxy again on 3 Apr 1831, but his position on this sweep was 1 degree too far south! See Harold Corwin's identification notes for NGC 4113.

400/500mm - 17.5" (2/24/90): very faint, very small, slightly elongated, small bright core. Located at the NW edge of Coma Berenices border. IC 3003 lies 12' SSE (not noticed).
