James Dunlop probably discovered NGC 376 = D 36 = h2378 with his 9" reflector on 2 Sep 1826 and recorded "a faint ill-defined nebula, about 1 1/2' diameter." He made a single observation and his published position is 9.5' ESE. JH recorded this cluster on two sweeps: on 12 Aug 1834 he logged "pretty faint, small, round, resolvable, pretty compact." On a later sweep he recorded it as a "globular cluster, a vS, vB knot of visible stars 15 or 20" diameter almost like a solid mass." His position and description on both sweeps is accurate, although Dreyer quotes DeLisle Stewart in the IC 2 notes, "only a D*, pos 270d, Dist 10" (from Harvard College Observatory NGC corrections). JH credited Dunlop as the possible discoverer (D 36) in the GC but not the Cape observations.

400/500mm - 18" (7/11/05 - Magellan Observatory, Australia): moderately bright, small, round, 30" diameter, a few individual stars or clumps are resolved. A 10' string of stars (Hodge Association 56) passing ~4' N and angles towards the NE. NGC 419 follows by 20'. Observation made through thin clouds.

600/800mm - 25" (10/17/17 - OzSky): at 397x; very bright, fairly small, irregular or triangular shape, 35"-40" diameter. A half dozen stars were resolved within the glow surrounded by a much fainter halo. Brighter and larger NGC 419 lies 20' ESE.

Lindsay 60 is 16' ENE (see NGC 419 for notes) and Lindsay 66 is 18' NW. The latter resolved into three brighter stars in a small string oriented WSW-NNE [length of 21"]. At 397x, the middle "star" was a very small knot, ~6"-8" diameter. This is probably the core of the cluster. The three stars seem surrounded by an extremely low surface brightness halo.

Henize N63 and N64 are a fairly similar pair of compact emission nebulae 27' WNW. Both are ~30" in diameter and separated by 1.4' NW-SE. They were easily noticed at 397x with N63 on the NW side slightly brighter. The contast was increased at 244x through an NPB filter. A mag 12 star lies 0.7' NW of N63.
