NGC 6397
This globular cluster is in the constellation Arc. It is also known as Caldwell 86. Lying about 7,600 lyrs away, it is one of the nearest globular clusters to Earth. This cluster has undergone a core collapse which has led to a very dense aggregation of stars at its center. The data was processed with PixInsight, RC-Astro tools and Affinity.
