Description

This is probably my last broadband capture for the season with the Milky Way rising. Broadband here always is rough given my bortle sky scale of 8 about 15 minutes from Detroit, Michigan. I tried my best, though.

The Hercules Cluster (Abell 2151) is a cluster of about 200 galaxies some 500 million light-years distant in the constellation Hercules. It is rich in spiral galaxies and shows many interacting galaxies, which I love to capture. The cluster is part of the larger Hercules Supercluster, which is itself part of the much larger Great Wall super-structure.
