M22 is located in the constellation of
Sagittarius.
It's the largest and brightest of the globular clusters cataloged by Messier
but is usually considered a bit less impressive than M13 at a much higher
declination for northern hemisphere observers; a perfect example of the
quality observing near the zenith. M22 is close, only about 9,000
light years away, and spans almost half a degree of sky.
