NGC 6823 and NGC 6820 in Vulpecula

NGC 6823 is an open cluster in Vulpec­ula, sur­roun­ded by emis­sion neb­ula NGC 6820 (Sh2-86) with a real dia­met­er of about 50 light years and 6000 light years away.

The most strik­ing fea­ture is the trunk-like pil­lar of dust and gas pro­trud­ing from the east side of the neb­ula towards the open cluster. The cen­ter of the open cluster is about two mil­lion years old and is pre­dom­in­antly rep­res­en­ted by many young, bright blue stars.

Long exposed Ha-data was used to bring out the details in the sur­round­ing of the open cluster.

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.
