I've been collecting NGC5236 data over the past couple of nights to have a try at putting together an LRGB image.
Starting with the excuses - I'm in the middle of Brisbane, my neighbor is attempting to turn night into day with his floodlighting, the moon has been at 70% illuminated and the clouds rolled in before I could get some G images so I synthesised the G channel in PS. It's no award winner but not bad for a first attempt. I'm still trying to understand how LRGB works in PS so have used this approach
