600/800mm - 24" (7/1/16): at 375x; very faint to faint, fairly small, slightly elongated, ~24"x20", low surface brightness. Located 7' NW of CGCG 162-041 and -039, two of the brighter members of AGC 1831. The redshift of UGC 8911, though, is roughly 1/2 that of AGC 1831, so this is a foreground galaxy.
