Albert Marth discovered NGC 901 = m 58 (along with NGC 900) on 5 Sep 1864 with Lassell's 48" on Malta and noted "eF, vS". His position is 3 sec of RA east and 3' N of NGC 900 (which was placed accurately) and at this offset is PGC 212967. This faint galaxy is not listed in any of the major galaxy catalogues based on the POSS. MCG misidentifies NGC 900 as NGC 901. The RNGC claims NGC 901is nonexistent (identical to NGC 900).

400/500mm - 17.5" (10/29/94): very faint, very small, round, 0.3' diameter, no concentration. Can view with direct view and hold continuously with averted vision. Located 2.8' NNE of NGC 900. Incorrectly listed as identical to NGC 900 in RNGC. Not listed in any of the major catalogues!
