John Herschel discovered NGC 2075 = h2943 on 23 Dec 1834 and logged "B, R, bM, resolved; the following of two on the same parallel [with NGC 2056], a star 9 mag intervening." His position is at the east edge of this nebulous cluster.

600/800mm - 24" (11/18/12 - Magellan Observatory, Australia): very bright, irregular, triangular-shaped, ~50" diameter. Near the center is a very bright knot consisting of a few extremely close stars. A couple of additional stars are resolved within the glow and a number of stars are near the edges. The cluster is surrounded by faint nebulosity (LMC-N213) which doubles the size of the object. Forms the vertex of an isosceles right triangle with mag 9.4 HD 38174 4.5' W and a mag 10 star 4.5' S. Third of three clusters with NGC 2056 9' WNW and NGC 2038 20' NW. NGC 2107 lies 24' ENE.
