Rob,
First of all, you’ve captured fantastic amount of data.
Second, your image is not RGB ..
L - 15 minutes (10 x 30 seconds, 10 x 60)
Ha (R) 16 minutes (2x 5 minutes, 5 x 2 minutes)
O2 (B) 10 minutes (5x 2 minutes)
G filter 10 minutes (5x 2 minutes)
So, the colour pallet is your personal choice as you are the painter.
