E.E. Barnard and Sherburne Burnham discovered IC 925 in a group around June 1892 with the 36" Lick refractor. Harold Corwin identifies IC 925 with LEDA 2508355, situated 1.1' NW of Barnard's position. Wolfgang Steinicke identifies SDSS J134319.69+553551.4 as IC 925 but this galaxy appears to faint to me (B = 18.8) to have been picked up, even in the 36". Due to general poor positions in the cluster, the identification is uncertain. See IC 917 for more.

Edwin Hubble catalogued LEDA 2508355 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 (#44), which included the IC 919 cluster. Hubble didn't assign or suggest an IC designation. Based on plates taken with the Mt. Wilson 60-inch in 1919, Pease described it as "MB, 20" x 5", p.a. 100°, spindle, gbM."

900/1200mm - 48" (5 /9/18): faint to fairly faint, thin edge-on ~20"x5", low surface brightness. Located 1.9' SW of mag 10.0 HD 238276 in AGC 1783. 2MASX J13431420+5536113 (= IC 923?) lies 0.8' SSW and IC 922 is 2.9' WSW. LEDA 2508607, just 0.5' NW, was extremely faint and small [V = 17.2], ~4" diameter.
