for some reason when taking LRGB in unity gain my reds and greens wont stack. I was imaging last night (unity gain) 120 secs on M101, I used SGpro and pixinsight, when it came to stacking I could do the L and the B but not red or green , keeps saying not enough stars found (even though I can see them on screen. Surely 120 secs is long enough in UG?
