3C 400.2 (SNR G053.6–02.2) in Sagitta
3C 400.2 is a medium sized supernova remnant with a size of 16 arcminutes in the constellation of Sagitta, which optical parts have been found on Mount Palomar red plated by Sidney van den Bergh in a systematic search published in 1978. The distance is estimated between 12’000 and 20’000 lightyears.
Deep Ha exposure was required to reveal the structure of this nebula. North is up in this image.

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.
