NGC 6820 is an emission nebula that surrounds open cluster NGC 6823 in Vulpecula. The nebula NGC 6820 is also called Sh 2-86.
The most striking feature is the trunk-like pillar of dust and gas protruding from the east side of the nebula. The huge pillars of gas and dust are probably formed when surrounding gas and dust is pushed and eroded away by radiation from nearby stars. NGC6820 lies about 6000 light years away.
This is a combination of 31 x 30 minute exposures using three filters that are very specific in their waveband pass. 15.5 hours of total exposure.
