This is an image of Abell Galaxy Cluster (AGC) 2151, also known as the Hercules cluster. It is a cluster of about 200 galaxies about 500 million light years in the constellation Hercules. The entire field will not fit in my FOV, so this image is centered approximately on galaxy IC 1182. The cluster is part of the larger Hercules Supercluster, which is itself part of the much larger Great Wall super-structure. This field also has a large number of interacting galaxies.
