NGC 3718 (Arp 214) and NGC 3729 in Ursa Major

NGC 3718 (left) and NGC 3729 (right) are two related galax­ies in the con­stel­la­tion of Ursa Major at a dis­tance of 42 mil­lion light years. Grav­it­a­tion­al inter­ac­tion caused the disk of NGC 3718 to be strongly warped, which res­ults in the S‑shaped appear­ance. The galaxy-group above NGC 3718 is Hick­son 56 at a dis­tance of roughly 425 mil­lion light years.

This is the first-light image of my par­ti­cip­a­tion at Black­bird Obser­vat­ory, Sierra Remote (Cali­for­nia), taken by our half-meter RCOS telescope.

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.
