John Herschel discovered NGC 2103 = h2968 on 23 Dec 1834 and recorded "pB; L; pmE; glbM; has a *13m in the middle." His position is accurate.

600/800mm - 24" (4/5/08 - Magellan Observatory, Australia): this LMC cluster and emission nebula appeared as a bright, very large oval glow, ~3'x2'. Excellent response to a UHC filter at 200x and with this combination the nebulosity has a very high surface brightness. Five stars down to 15th magnitude are involved unfiltered with mag 12.7-magnitude Sk -71°51, an unusually hot and intrinsically bright star (O2-class), at the center. The cluster is the O-association LH 110.
