Albert Marth discovered NGC 2729 = m 141 on 3 Mar 1864 and noted "vF, vS, R". His position is 6 sec of RA west of UGC 4737, but there's no question of the identity. The mag 15 star at the east edge was described as nebulous by Karl Reinmuth in his photographic survey based on Heidelberg plates.

400/500mm - 17.5" (3/12/94): faint, very small, round, initially appeared elongated E-W due to a mag 15 star attached at the east end which is not cleanly resolved (16" ESE of center). Faint halo 30" diameter is weakly concentrated, very small brighter core. A pleasing bright double star mag 9.9/11 at 24" lies 3' S.
