Lewis Swift discovered NGC 1121 = Sw. I-4 on 9 Nov 1884 with his 16-inch refractor. His RA was 13 seconds too large. Herbert Howe measured an accurate position in 1898 using the 20" refractor at Chamberlin Observatory as well as Porter in 1908 at the Cincinnati Observatory.

400/500mm - 17.5" (12/28/94): fairly faint, small, elongated 2:1 N-S, 0.6'x0.3', well concentrated with a small bright core and a stellar nucleus. Located 1.7' SSW of a mag 10 star in the northwest corner of Eridanus.
