|M22 is a truly spectacular example of a star cluster since it is
very near and, as we view it, towards the center of the galaxy. Thus,
when M22 is observed we see hundreds of thousands of its constituents as
well as a myriad of stars in the foreground/background. The ultimate of stars upon stars.
M22 is estimated to be 10,000 light years away and around 65 light years across
. This cluster can be seen easily in binoculars near the star atop the
"teapot" asterism of Sagittarius.
