Perseus Len­ticular (NGC 1023)

NGC 1023 is the nearest len­ticular galaxy to the milky­way at a dis­tance of 34 mil­lion lightyears and the bright­est mem­ber of a galaxy group with prom­in­ent mem­bers like NGC 891 and NGC 925.

The most obvi­ous com­pan­i­an is NGC 1023A to the left, which is the reas­on why both objects are cata­logued as Arp 135. Through the disk of lumin­ous mater­i­al, the bright cent­ral bulge and a bar can be seen, thats why NGC 1023 is clas­si­fied as SB0.

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.
