Caldwell 95 is a star cluster (NGC 6025) in Triangulum Australe — a family of stars bound by gravity. It appears as number 95 in the Caldwell catalogue, Sir Patrick Moore's 1995 list of 109 bright deep-sky objects for amateur astronomers. It spans roughly 11.4 arc-minutes on the sky. At about magnitude 5.1, it can be glimpsed with the unaided eye under dark skies.
Although it appears about 11.4′ wide on the sky, its real span is roughly 19.9 light-years — the difference is a measure of how far away it lies.
Observing Caldwell 95
Caldwell 95 lies in the constellation Triangulum Australe and is best placed in the evening sky around May. Its maximum altitude above the horizon depends on your latitude. It sits far enough south to be circumpolar from mid-southern latitudes, and never rises for most of the northern hemisphere. At its brightness it can be found with the unaided eye under a dark sky and is easy in binoculars.
