E.E. Barnard and Sherburne Burnham discovered IC 922 in a group around June 1892 with the 36" Lick refractor. Harold Corwin identifies IC 922 with LEDA 2507977, situated 18 seconds of RA west (2.6' W) of Barnard's position. This is the brightest galaxy in the immediate area. But Francis Pease, in his 1920 publication on nebulae found on Mt. Wilson 60-inch plates, as well as Wolfgang Steinicke, identified IC 922 with LEDA 3483133, situated 2.5' due east. LEDA 3483133 is just 0.5' S of Barnard's position, and Pease considered this number as one of only 3 in the group with solid identifications. But without knowing the general accuracy of his position, either identification is possible. See IC 917 for more.

Edwin Hubble catalogued this galaxy based on a plate taken with the 24-inch Yerkes reflector while working on his 1917 PhD thesis "Photographic Investigations of Faint Nebulae" (published in 1920). It was found in his Field IV of nebulae (#40), which included the IC 919 cluster. Hubble didn't assign or suggest an IC designation.

900/1200mm - 48" (5 /9/18): fairly bright, fairly small, round, ~20" diameter, gradually increases to the center. This galaxy is one of the brighter members of AGC 1783 at a light-travel age of ~920 million years. IC 923 lies 2.5' E.
