Albert Marth discovered NGC 7732 = m 589, along with NGC 7731, on 27 Oct 1864 and noted "vF, pL." His position is accurate.

400/500mm - 17.5" (11/30/91): very faint, fairly small, elongated 2:1 E-W, low even surface brightness. Located just 1.0' S of a mag 11 star. Forms a close pair with NGC 7731 1.4' NW.

600/800mm - 24" (11/24/14): faint, fairly small, elongated 5:2 E-W, ~35"x14", low even surface brightness. Forms a pair with NGC 7731 1..5' NW. A mag 11 star is 1' due north.

900/1200mm - 48" (10/26/16): at 610x; fairly bright, fairly large, very elongated 3:1 or 7:2 E-W, 1.4'x0.4'. There was no brighter core in the central region but the galaxy was asymmetric, appearing wider and brighter on the west end [SDSS shows a series of blue HII knots]. At 697x, the western end was mottled and occasionally appeared to bulge out a bit to the south on the southwest side.
