Cres­cent Neb­ula (NGC 6888) in Cygnus

NGC 6888 (Cald­well 27) is one of the more intriguing objects in our galaxy as it is loc­ated around HD 192163, a 7.5‑mag Wolf-Rayet star. It has long been believed that this extremly lumin­ous sun is heat­ing a part of it out­er atmo­sphere which has a dia­met­er of roughly 20 lightyears. The Cres­cent Neb­ula spans an area of about 18x13 arc minutes in the con­stall­a­tion of Cygnus, roughly 4700 lightyears away.

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.
