NGC 7822 is a young star forming complex in the constellation of Cepheus.
These are old data I found on my drive and that I publish for the 1st time.
The O3 layer is probably the worst I ever collected with the ASI 1600.
Overall limited integration around 8h o/w 3h of O3 wheras I tend to shoot 20h+ from my bortle 8-ish place.

I pushed data very far this time.
