I was able to get some data on M101 a few days ago when it was clear. I was able to stack the individual LRGB files fine. Due to issues and bad frames, I had 104 Light frames, 34 Red frames, 16 Green Frames, 31 Blue frames. Other than a small water drop that seems to be on the lens all night when I stretch(to view) them in pixinsight they look to have good data in all the channels. Processing seems to go ok until I combine the RGB into one image. The Reds dominate even when using LinearFit but I can still get some blue and a bit of green to show ok with tweaking. When I combine that to my Light file, I lose all color or if it is there it is very faint, and I cannot tell it is there.
Is this because I have a lot more lights than the other channels and that is drowning out the color? How is the best way to stack when you have such a big difference in the number of frames? Should I be stacking less of the L, R and B to make up for the fact there are so few G frames?
I can post some files when I get home if that helps.
