The Her­cules Galaxy Cluster (Abell 2151) is a cluster of about 200 galxies some 500 mil­lion light-years dis­tant in the con­stel­la­tion of Her­cules. It is rich in spir­al galax­ies and shows many inter­act­ing galaxies.

The blu­ish, nearly edge-on glaxy in the cen­ter of the image is NGC 6045A shin­ing at 14.8 mag, the two inter­act­ing spir­al to the right are NGC 6050A/​B. Fur­ther to the right, IC 1182, shows a blue tid­al tail and shell of evid­ently accreted stars and gas.
