David Todd discovered IC 591 = Todd 22 = J. 1-177 on 6 Feb 1878 during his search for a trans-Neptunian planet using the 26-inch Clark refractor at USNO. It was not assigned an NGC designation as no position was given. But Harold Corwin found his sketch is a good match with UGC 5458 (specifically a mag 13 star 86 seconds of time west). Javelle independently discovered this galaxy on 31 Mar 1892, so the IC position is accurate. UGC doesn't label UGC 5458 as IC 591.

400/500mm - 17.5" (2/13/88): faint, small, slightly elongated, even surface brightness. Located 15' W of center of dwarf galaxy Leo I in the same 140x field (35')!
