UGC 5423 is sometimes listed as a dwarf member of the M81 group as it lies 1.1? NE of M82. It is also known as M81 DW-B in lists of the M81 group. But the distance is ~29 million l.y. based on the TRGB method, so it lies in the background.

900/1200mm - 48" (4/16/15): at 488x; faint to fairly faint, moderately large, elongated NW-SE, 0.8'x0.5', low but irregular surface brightness. There is no core but a very small brighter knot (perhaps 5" diameter) is at the northwest end. CGCG 333-016 lies 2.5' SW.
