Caldwell 93 is a star cluster (NGC 6752) in Pavo — a family of stars bound by gravity. It appears as number 93 in the Caldwell catalogue, Sir Patrick Moore's 1995 list of 109 bright deep-sky objects for amateur astronomers. It spans roughly 13.2 arc-minutes on the sky. At about magnitude 6.3, it is a rewarding binocular and small-telescope target.
Although it appears about 13.2′ wide on the sky, its real span is roughly 49.9 light-years — the difference is a measure of how far away it lies.
Observing Caldwell 93
Caldwell 93 lies in the constellation Pavo and is best placed in the evening sky around July. Its maximum altitude above the horizon depends on your latitude. It is best placed for observers in the southern hemisphere, and sits low for those far north. It is a comfortable target for binoculars and small telescopes.
