Francis Leavenworth discovered NGC 1092 = LM 1-66 (along with NGC 1091 and 1098) on 17 Oct 1885 with the 26" refractor at Leander McCormick. Herbert Howe's corrected position, repeated in the IC 2 notes, is accurate. Howe also noted that NGC 1092 is "considerably brighter than its companion" although both were described by Leavenworth as "vF".

400/500mm - 17.5" (11/26/94): faint, small, round, 40" diameter, increases to a bright core. Brighter of a close pair with NGC 1091 1.8' WNW. Last in HCG 21, consisting of five faint galaxies with NGC 1091, NGC 1098, NGC 1099 and NGC 1100.
