Found some 22,000-25,000 light years away from Earth is the Hercules Globular Cluster, which is also known as Messier 13 (and is designated as NGC 2605). Consisting of several hundred thousand stars, the Hercules Globular Cluster is one of the brightest star clusters in the northern sky.
Martin Dufour has been taking pictures of this cluster every year since 2011. This is his 2021 version.
