LRGB Help.

I'm still having trouble with LRGB imaging but I think I'm closing in on the problem.

I shot these last night and there are bloated stars in all the images except red. All images are only 120second exposures. I notice that the stars aren't as big in the LUM as they are in the GREEN and colour was shot at 2x2 so it may be that the gain of the camera is too high, so something like that. There is no gain setting in maxim, I believe it's set on the camera.

The result of all this is that the green and blue stars are way bigger than the red ones and you get the halo effect seen in RGB.

I was going to try again without binning but does anyone have a clue what I can try after that?
