![]() | M22, or NGC6656, a globular cluster in the constellation Sagittarius. A conspicuous naked eye object, M22 is the brightest globular cluster visible from the northern hemisphere. About 10,000 light-years from us, M22 is about 65 light-years across. In 7x50 binoculars, it's very easy to find M22. It is bright and easy to find off the north-eastern tea pot (lid) asterism of Sagitarrius. It looks like a fuzzy disk with no hint of resolution. Very bright. A telecscope would definately resolve this globular. This is a large globular, easily rivaling the size of M13. An 8-inch scope at 49X, many stars are visible. For a globular cluster, it is fairly loose. 122X provides a fantastic view. Stars are visible all the way into the center, with a diffuse glow as a backdrop. The cluster will appear to be slightly elliptical in shape. This one is definitely a crowd-pleaser. |
