Messier 4 - A Nearby Globular Cluster

Here's a shot I snapped of the Messier 4 Globular Star Cluster on May 14, 2015 at Frosty Drew Observatory in Charlestown, Rhode Island, USA. Messier 4 is found in the constellation Scorpius and has a size of about 75 light years in diameter. Residing at only 7,200 light years distant, M4 is one of the two closest Globular Clusters to Earth.
