E.E. Barnard discovered UGC 10029 on 15 Jul 1890 while searching for d'Arrest's Comet with the 12-inch refractor at Lick Observatory. He noted in his logbook "F, pS, indef, difficult, 12 1/2m." He has a small sketch that shows a 9.5 mag ~3' SE. The star is shown as the middle of three nearly on a line and the sketch is a good match with UGC 10029. He added "Perhaps a very small neb, 5' f and 1' N." At this offset from UGC 10029 is CGCG 050-104, so the identification is certain.

600/800mm - 24" (6/13/15): at 375x; fairly faint, fairly small, oval 4:3 E-W, ~28"x21", small slightly brighter nucleus but overal fairly low surface brightness. CGCG 050-104 lies 5.6' ENE.
