John Herschel discovered NGC 2732 = h539 on 2 Sep 1828 (sweep 171) and recorded "pB; S; E from nf to sp. Has a star nf." There is nothing at his position (marked as uncertain), but ~3 minutes of time east is UGC 4818 and his description is a perfect fit with this gaalxy. Heinrich d'Arrest measured the position on 3 nights (first on 1 Dec 1863), which was used in the NGC.

400/500mm - 17.5" (4/6/91): fairly bright, small, elongated 5:2 SW-NE, 1.6'x0.7, small bright core, stellar nucleus. A mag 12 star is at the NE tip 0.8' from center. Forms a pair with UGC 4832 4.1' E.
