M22 - Globular Cluster in Sagittarius
Copyright 2003 John Hodge
A wonderous globular cluster of over 70,000 stars (that many have actually been counted!), M22 stands as one of the four brightest clusters in the sky and the brightest commonly seen from northern latitudes. Easily seen in binoculars, it occupies an apparent area almost exactly that of the full moon...one-half degree wide. M22 lies at a distance of 10,400 light-years, making it one of the closest globular clusters to us.
