NGC 7023 (Iris Nebula) LRGB

Taking a break from narrow-band this is my first proper attempt at an LRGB image. I thought it would be easier to composite - it wasn't.
10 x 15min subs each L, R, G, B. 
TV NP127is @ native f/l (660mm)
Atik 490EX @ 1x1
Losmandy G11 + Gemini
TV Pronto + Lodestar guider.

This image needed a couple more tweaks - SCNR in PixInsight to remove a green caste I hadn't noticed, and boosting the red in the core which had got washed out somewhere along the line. It's trickier than I thought trying to colour balance an LRGB!
