The Owl Luster contains more than 100 stars, is about 8000 l-y distant, and forms a shape of an owl, complete with wings. Two bright stars create the "eyes" - the brighter one, 5th magnitude naked eye phi(1) is a question. If it is a member, it is one of most luminous stars known - 200,000. Or, it could be a foreground star projected onto the cluster.
It was a difficult night for photography, due to some hazy high level clouds (at least thats my story), and a lot of subframes were rejected. Processing was simple, but difficult to control the "halo" around phi(1) in particular.
