Her­cules Galaxy Cluster (Abell 2151)

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.

About Me

Hello, my name is Martin Rusterholz. I’m a Swiss amateur astrophotographer living near Zurich, the biggest town in Switzerland. My interest in astronomy started when I was 16. At that time, I built my first Newtonian telescope and mount. I studied physics at the Swiss Federal Institute of Technology (ETH) which was the only study including at least some aspects of astronomy and astrophysics. “Looking at the nights sky is an experience touching everybody deeply inside, something common to all human beings independent to the language spoken by the individuals”. Deep-sky astrophotography is my passion.
