M13 - The Great Globular Cluster

 

M13, also known as the Great Globular Cluster in Hercules or NGC 6205, is one of the most prominent globular clusters in the Northern Hemisphere. It contains an estimated 100,000 to 300,000 stars, packed into a region about 145 to 150 light-years in diameter. The cluster’s core is dense, with stars spaced only a few light-days apart, creating a brilliant, concentrated appearance.

 

M13 has an apparent magnitude of 5.8, making it faintly visible to the naked eye under dark skies and easily observable with binoculars or a small telescope. It appears as a bright, fuzzy ball with a denser core, and larger telescopes can resolve individual stars.

 

I captured this last week over a couple of nights.
