M13 - The Great Hercules Cluster. This 11.65 billion year old formation of stars is one of the most impressive globular clusters in the northern hemisphere. Containing over 300,000 stars packed into a 145 light year sphere, the center of this object is 500 times more concentrated than its outer perimeters.

A globular clusters consisting of hundreds of thousands of stars. This is where the Arecibo telescope sent out a signal in hopes of it reaching a civilization here many thousands of years from now
Messier 13 Globular Cluster in Hercules. (JUL2006). M13 is one of the largest example of globular clusters with an estimated mass of 600,000 suns. In The Sirens of Titan, Kurt Vonnegut writes "Every passing hour brings the Solar System forty-three thousand miles closer to Globular Cluster M13 in Hercules -- and still there are some misfits who insist that there is no such thing as progress."

The Great Globular Cluster in Hercules, is a globular cluster of about 300,000 stars in the constellation of Hercules. M13 is about 145 light-years in diameter, and is 25,100 light-years from Earth. Spiral galaxy NGC 6207 (30 million light years away) can be seen toward the bottom right.
Imaged in June 2017 and was an experiment of using a ton of short (less than 1 minute) exposures. Roughly 800 individual images (400 in Luminance, 150 in Blue, 150 in Red, and 100 in Green). 6 hours total integration.
