Francis Leavenworth discovered NGC 1180 = LM 1-82 (along with NGC 1181 = I-83) on 31 Dec 1885 with the 26" refractor at Leander McCormick Observatory. Leavenworth's generally poor positions are close enough here so the identification NGC 1180 = PGC 11435 and NGC 1181 = PGC 11427 is certain. For some reason Howe could not find these galaxies near Leavenworth's position but did find NGC 1150 and 1151 about 5 min of RA west of Leavenworth's positions and assumed they were NGC 1180 and 1181. Dreyer even added the comment "are they perhaps = 1150 and 1151?". But these are two different pairs, roughly where Leavenworth placed them. Because of Howe's error, RNGC claims NGC 1150 is identical to NGC 1180 and NGC 1151 is identical to NGC 1181.

400/500mm - 17.5" (1/28/00): extremely faint, very small, slightly elongated N-S, 0.4'x0.3', weak concentration. Forms a close (physical) pair with NGC 1181 2.4' SW. Located 2' WNW of a mag 12 star. NGC 1191 and 1192, background members of HCG 22, share the same redshift.
