Messier 2 - The Globular Cluster in Aquarius

Messier 2 is an ancient globular cluster in the constellation Aquarius. It is quite old, some stars inside this cluster have been around for 13 billion years and it contains atleast a hunderd thousand stars.

I captured this during a Messier Marathon I did in August 2025.
