Sh2-86
A large but relatively faint, emission nebula in Vulpecula. it contains the small reflection nebula NGC 6820 and the open cluster NGC 6823. It is most well known for the prominent pillar in the brighter core, though many other fascinating substructures can be seen in the dimmer parts of the nebulosity. The main body of the nebula is crossed by a dark cloud.
The image was taken with Ha (mapped to red), S-II (mapped to yellow/green), O-III (mapped to cyan) ultra-narrowband filters as well as with the g’ photometric filter (mapped to blue) to pick up the faint reflection nebulosity. The O-III signal is weakest but present in the bright core. Stars are from the sulfur-II plates and are thus without colour. Processing in AstroPixelProcessor, StarTools, PixInsight and Photoshop.
