Messier 70

M70 is a globular cluster in the constellation Sagittarius. It has a very dense core, and this image has been quite thoroughly stretched to show both the inner crowding and the outer more sparse regions. M70 is about 65 light-years across and about 30000 light-years away.


In a 8" scope, this globular is small and tight, but fairly bright. 188X offers about the best view. With averted vision, a few stars can be resolved, but direct vision reveals only a fuzzy smudge of light with a bright core. This cluster isn't very impressive through a 8", but it looks like it has some potential for larger scopes.
