I reshot them tonight at 0 gain, perfect result!

Paul,
Lights , Flats and Bias all at Gain 0 and camera left cooled at -10C ( using L Extreme filter )
I’ve used Gain 100 for both short (60sec ) and long exposures ( 300sec ) with and without filter , Bortle 3 and Bortle 8 and I found Gain 0 to achieve slightly better results on average
Better results meaning slightly less noise floor , more fine detail and contrast across the field
I’m leaving my camera at Gain 0 cooled to -10C at both sites all year round
Cheers
Martin
