Easily visible to the naked eye, M6 is a suberb object for a small telescope. The cluster is fairly small and scattered. The main stars are quite bright and bluish, and form a distinct outline of a butterfly with wings outstretched. In an 8" telescope at low magnification, the cluster is a facinating sight.
