Stephane Javelle discovered IC 1125 = J. 2-789 on 10 Jun 1893. His position is on the northwest side of UGC 9888 and the identification is certain.

Harold Corwin suggests that IC 1128 (discovered by Lewis Swift on 28 May 1889) is probably IC 1125 with a 5 minute error in RA and a 5 arcmin error in declination. The CGCG identifies CGCG 022-018 = UGC 9939 as IC 1128. This galaxy is much closer to Swift's position (similar RA, but 12' to the north). But this galaxy has a companion (CGCG 022-017) that Corwin feels that Swift would have also picked up. Most modern sources (including HyperLeda) follow CGCG.

600/800mm - 24" (8/1/19): at 322x; fairly faint, fairly small, slightly elongated 4:3 ~N-S, ~40"x30", broad weak concentration. The halo appears slightly irregular in shape and brightness. A mag 13 star is 1' NE.

24" (6/23/17): at 260x; fairly faint, oval 3:2 or 5:3 NNW-SSE, ~40"x25", weak concentration but no distinct core. A mag 13.3 star is 1.2' NE. Located 12' WNW of mag 8.3 HD 139514.
