Many thanks for your comments.
Picking up on Doug's suggestion - I've tried increasing saturation in Photoshop (+25-+35 in Master or Red) without significant increase in colour, just brought out red noise. BTW this is the first galaxy I've imaged using the LRGB method and I've only been doing this type of imaging/processing since the beginning of the year. Sooooooo much to learn, soooooo little time! Any advice from the Forum about how to improve saturation would be greatly appreciated.
Thanks in advance for your help. Russ
