M22 is a Shapley-Sawyer Class VII globular cluster lying 9,785 light-years from Earth in Sagittarius. That makes it one of the closest globular clusters. While most globular clusters are found far from the plane of the Milky Way in fields only sparsely populated with stars, M22 lies close to the heart of the Milky Way. Thus, it is a real treat to view it amidst a field of countless colorful Milky Way foreground stars. The considerable amount of galactic dust lying between us and M22 also reddens the cluster, giving it a slightly yellowish tinge.

Exposures: L:R:G:B = 25:25:25:25 minutes = 3 hours, 5 minutes total exposure at f/6.8.
