NGC 7640 in Andromeda

NGC 7640 is a mag 11.5 bright SBc-type galaxy in the con­stel­la­tion of Andromeda with an appar­ent size of 10’x2.2′. The shape of the spir­al arms clearly shows the clas­si­fic­a­tion of SB, but it appers to have under­gone grav­it­a­tion­al inter­ac­tion in the past. The dis­tance is estim­ated to be around 28 mil­lion lightyears, while the phys­ic­al dia­met­er is 90’000 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.
