DeLisle Stewart discovered IC 5152 = DS 732 on a plate taken in 1899 at Harvard's Arequipa station in Peru. He noted "F, cL, cE at 150°, cbM." This galaxy is often listed as a Local Group member though is likely outside the Local Group.

200/250mm - 11" (8/8/04 - Haleakala Crater): at 127x appeared moderately bright, fairly large, elongated 2:1 ~E-W, roughly 2.5'x1.3', broad weak concentration to a slightly brighter core. A 7.7-magnitude star (HD 209142) is superimposed just north of the west end of the galaxy and somewhat hinders the view. With averted vision the glow appears to extend slightly west of the bright star and the core is just a small brightening to the east of the star.

400/500mm - 18" (7/6/02 - Magellan Observatory, Australia): this nearby Irregular galaxy (probably just outside the Local Group) was viewed at 171x and 228x. It appeared bright, large, elongated 2:1 ~WNW-ESE, ~3'x1.5'. A mag 7.9 star (HD 209142) is perched on the NW end and detracts from viewing. It's very surprising that John Herschel missed this galaxy as it is quite large and relatively prominent. Gradually concentrated to a brighter 45" core.
