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.
