E.E. Barnard and Sherburne Burnham discovered IC 923 in a group around June 1892 with the 36" Lick refractor. Harold Corwin identifies IC 923 with LEDA 3483133, situated 1' SSW of Barnard's position. Wolfgang Steinicke identifies LEDA 3483133 as IC 922 and labels LEDA 2508355 (very close to Barnard's position) as IC 923. Hubble, in his 1917 PhD thesis on "Photographic investigations of faint nebulae", stated LEDA 3483133 (#43 in his table) was "very probably" IC 925. Due to Barnard's generally poor positions in the cluster, the identification is uncertain. See IC 917 for more.

900/1200mm - 48" (5 /9/18): fairly faint to moderately bright, small, round, 15" diameter, very small brighter nucleus. This member of AGC 1783 is located 2.6' SW of mag 10.0 HD 238276. IC 925 lies 0.8' NNE and IC 922 is 2.5' W.
