This image has captured two galaxy clusters paralleled with a degree interval positioned almost on a boundary between Hercules and Serpens Caput. They locate at about 1.3 degrees south of the comparatively large-scaled Hercules Cluster (Abell 2151), contain about 50 or 60 member galaxies and are lying at 400 or 500 million light years away. Honestly, the clusters are not good-looking objects but a central galaxy UGC10143 in Abell 2147 is comparatively large and striking.
