John Herschel discovered NGC 1862 = h2789 on 31 Jan 1835 and logged "vF, R, 30"." His position from this single sweep is 1.3' too far west.

600/800mm - 24" (11/18/12 - Magellan Observatory, Australia): fairly faint, fairly small, irregular round, 25" diameter. Two mag 15-15.5 stars are resolved on the north side [6" separation] and a knot on the south side just resolves into a 4" pair. A wide 30" pair of mag 11/12.5 stars is 2.5' S.
