Globular Cluster M13
Globular Clusters are great orb-like masses of stars in orbit around our galaxy. They are almost like a mini galaxy, only they are made up of typically a single type of star (usually hot blue stars) and they lack any gas or dust. What lies in their center is anyone's guess. If you lived on a planet there, your night sky would be an incredible star filled wonder, and night would probably not be dark like it is here. A large halo of these clusters circles our galaxy, and M13 is one of the more impressive ones.
My image is a stack of about 15 images varying from 5secs to 3 minutes, shot with my Canon 300D at ISO 1600 using my SN-10 telescope.
