Description

Using some old data from the remote scope in Spain, I decided to process it as a bi-colour image using the pixel maths formula of R = Ha, G = OIII+0.15*Ha and B = OIII. I had some trouble bringing up the faint blue in the middle of the nebula, [there wasn't much data to play with anyway], without making the stars too blue in the process. I think I have just about managed to obtain what I hoped for. The Ha subs were 10 minutes in length, as were the OIIIs. There were 15 of each. Integration time was 5 hours.
