One of the brightest globulars in the sky, M-22's brightest stars are easily resolvable. Unfortunateky, this object does not rise high above the horizon from temperate latitudes. On a dark night it can be seen with the naked eye; it certainly is visible in the finder. Slightly on the loose side, M-22 has a large equatorial bulge and a reddish appearance. It lies in an area rich with globular clusters.
