Pegasus II Cluster of Galaxies is a group of galaxies with three bright members and about 50 to 60 fainter galaxies in constellation Pisces. In the center, we see NGC 7501 (mag 13.6), NGC 7499 (below) and NGC 7503 (upper left). NGC 7501 was discovered on September 2, 1864 by the astronomer Albert Marth and lies about 570 million light-years away.

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.
