Description

M13 - The Great Globular Cluster in Hercules

So tonight, as a little birthday treat, I went outside and did a bunch of quick, rapid imaging blitz type things...all clusters, which I could grab 20 mins on and then move to the next.

This is M13, or the Great Globular Cluster in Hercules. It is about 145 light years in diameter, and lives about 25,000 light years from earth. Globular clusters are very tightly packed, spherical groupings of stars, and are found in the galactic halo.

If you look closely at the photo, to the 1 or 2 o'clock side of the cluster, there are 2 very small, faint galaxies. The larger of the two is NGC 6207 (which is a 12th magnitude galaxy (or very faint!), and the smaller one between the cluster and NGC 6207 is IC 4617, which is even fainter.
