The Pegas­us I Galaxy Cluster is a smal­ler group of galax­ies with about 13 mem­bers in the con­stel­la­tion of Pegas­us near the bor­der to Pisces. The cent­ral, ellipt­ic­al galax­ies are NGC 7626 (left) and NGC 7619 (right), both shin­ing at about 11.1 mag. Both galax­ies have been dis­covered by Wil­helm Her­schel 1785. The dis­tance to NGC 7619 is about 180 mil­lion lightyears, while NGC 7626 is some­what closer at 140 mil­lion lightyears.

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.
