M22 (ngc6656)
Hello everyone.
A nice GC taken a few months ago when the sky was clear.
Messier 22 is an elliptical globular cluster in the constellation of Sagittarius. This object is surounded by a range of large young hot stars and old ones varying in luminosity on the HR scale (Hertzsprung-Russell). M22 is one of the nearer globular clusters to Earth at a distance of about 10,600 light-years.
