Truman Safford discovered NGC 118 = Sf 91, along with NGC 114 = Sf 90, on 23 Sep 1867 with the 18" refractor at Dearborn Observatory. The discovery was not published until 1887 and Dreyer included it in an appendix to the NGC. Wilhelm Tempel (IV-3) independently found the galaxy on 27 Sep 1880 (along with NGC 114 and NGC 124) with the 11" refractor at the Arcetri Observatory and he is credited with the discovery in the NGC. Tempel's micrometric position matches UGC 264 = PGC 1678.

400/500mm - 17.5" (10/8/88): faint, very small, round, small bright core. Forms a twin of NGC 114 4' W. NGC 124 lies 10' ESE.
