Steve's Notes

NGC 3766
13.1" (2/18/04 - Costa Rica): this is a superb naked-eye open cluster in Centaurus with several hundred stars resolved in a 15' field. It contains a very dense mass of stars in the central 5' that are seemingly arranged in a spiral configuration as well as a beautiful string of stars running SW-NE on the south side of the cluster. A mag 7.2 M-type reddish star (SAO 251470) lies at the NW end, a mag 7.5 star is on the east side (HD 306799) and a mag 7.1 star (HD 100943) is on the SE side. This impressive cluster was a surprising showpiece as it wasn't on my radar as an excellent cluster. Located 50' NW of a mag 5.1 star and 1.4¡ due north of mag 3.1 Lambda Centauri.
