NGC 6820 and NGC 6823

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.
