NGC 6820 is a small reflection nebula near the open cluster NGC 6823 in Vulpecula. The reflection nebula and cluster are embedded in a large faint emission nebula called Sh 2-86. The whole area of nebulosity is often referred to as NGC 6820

Taken with one of the newish OSC Narrowband filters. This is 54 of 63 x300s, ISO800 on my old faithful modded Canon 1100d. I love this filter! Instant small stars and bright nebulae. Easy to process as an OSC image.

This was in a good position last night after I had re-collimated the newt, i.e. above the neighbours house between the trees at 22o altitude and it looked great on a 30s sub. Couldn't quite get the colour into the middle of the stars. Must get back into using Pixinsight now the darkness is back, then I can fix that.

Forgot all this stuff is recorded by DSS, very useful! I used Bilinear alignment, seems to produce better results every time, and used "Align RGB Channels in Final Image". They are master calibration frames.

A Revelation 1.25" UV/IR filter installed as close to the camera sensor has done it's job a bit too well and cut the Hydrogen Alpha wavelengths limiting the red on the wall around the Horsehead.
