Messier 22 or M22, also known as NGC 6656, is an elliptical globular cluster of stars in the constellation Sagittarius, near the Galactic bulge region. It is one of the brightest globulars that is visible in the night sky. The brightest stars are 11th magnitude, with hundreds of stars bright enough to resolve with an 8" telescope.
Facts about M22 by Keith Turnecliff
With a visual magnitude of 5.5, M22 is the brightest globular cluster visible from the Long Itchington. However, as it lies in the southern constellation Sagittarius, M22 never rises very high in the sky and can’t really be observed in all its glory from the northern hemisphere. It doesn’t offer a view as impressive as those of Messier 13 in Hercules and Messier 5 in Serpens.
