E.E. Barnard and Sherburne Burnham discovered IC 928 in a group around June 1892 with the 36" Lick refractor. Harold Corwin identifies IC 928 with LEDA 2506714, situated 3.2' SSE of Barnard's position. There are several other slightly fainter galaxies near this galaxy and the positional discrepancy is relatively large, so this identification is very uncertain. In fact, Francis Pease identified 2MASX J13433923+5537534 as IC 928 (Corwin labels this galaxy as IC 926) based on plates taken with Mt Wilson 60" in 1919 (published in 1920). Steinicke identifies LEDA 2509027 (only 0.9' NE of Barnard's position) as IC 928, but Corwin labels this galaxy as IC 929! See IC 917 for more.

900/1200mm - 48" (5 /9/18): faint to fairly faint, very small, round, 10" diameter, low surface brightness. This member of AGC 1783 is situated 2.2' E of a mag 10.9 star and less than 5' S of the core of the cluster.
