Nice work Houghy!
I only had 60k or so jpegs that you sent me too work with so I was very limited in what I could do but here are my versions of them
There is so much HII in the Orion region that with such low res jpegs to work with it was hard to know what was faint nebula and what was colour noise
It was fun though, thanks.
Good to have the raw data to work with
