Messier 80

M80, a globular cluster in the constellation Scorpius, is quite distant at over 27,000 light-years, and also one of the densest globulars. It contains several hundred thousand stars within a diameter of around seventy light-years.

In a 8-inch scope, this cluster is small, but bright. At 122X, it appears mottled. With averted vision, a few individual stars can be resolved around the edges. Higher powers may improve the view.
