The Rosette Neb­ula (Cald­well 49) is a large, cir­cu­lar H II region loc­ated near one end of a giant molecu­lar cloud in the Mono­cer­os region of the Milky Way Galaxy. The open cluster NGC 2244 (Cald­well 50) is closely asso­ci­ated with the nebu­los­ity, the stars of the cluster hav­ing been formed from the neb­u­la’s mat­ter. The cluster and neb­ula lay at a dis­tance of some 5,200 light years from Earth (although estim­ates of the dis­tance vary con­sid­er­ably) and meas­ure roughly 130 light years in diameter.

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.
