Description

After several months I am back to deep sky imaging....

NGC 6820 is an emission nebula that surrounds open cluster NGC 6823 in Vulpecula, near M27, the Dumbbell Nebula. The nebula NGC 6820 is also called Sharpless catalog Sh 2-86.

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, NGC 6823 in the west. The center of the open cluster is about two million years old and is predominantly represented by many young, bright blue stars. Outer parts of the cluster intimately involving pillars of emission nebula NGC 6820, contain even younger stars.
Open star cluster NGC 6823 is about 50 light years across and lies about 6000 light years away
