Bizibilder’s first Deep Sky Object Photo

Hercules Cluster

Bizibilder is quite proud of his first DSO picture.  It is of the star cluster known as “The Great Globular Cluster” or M13 (Messier’s catalogue number 13)in the constellation of Hercules. It is a cluster of thousands of stars and is about 145 light years in diameter and is about 25,100 light years away.  It can be seen with the naked eye (just!) or binoculars will show it easily as a smudge.  This was taken with an 8” (200mm) diameter telescope.

(Eight minutes exposure, processed a little to eliminate light pollution.)

I’ve added a close up of the “core”:
