NGC 383 group of galax­ies, also known as Arp 331, is a galaxy chain in con­stel­la­tion Pisces. Its cent­ral mem­ber, NGC 383, is the biggest galaxy slightly right from the cen­ter of the image. It lies at a dis­tance of about 209 mil­lion lightyears and has a true dia­met­er of about 135’000 lightyears. NGC 379, NGC 380, NGC 383, NGC 384 and NGC 385 (from top to bot­tom) are sus­pec­ted to be closely related. North is up in this image.

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.
