Very nice Jase! You did a darn good job getting rid of that glare I must say!!

You beat me to the punch too!! I've just started on this target myself but I only managed 3hrs of Ha before the clouds rolled in and stayed there!!! I was going to post what I have so far - but now I guess I'll have to wait! .

No, DON'T normalise your RGB masters before combining in CCDStack - it will destroy your colour balance. I usually start with the combine factors reflecting the relative QE of my chip at the centre of each filter's passband (ie R=1.45, G=1.14, B=1.0) (assumes equal length exposures). I then tweak the factors a bit to taste of course. Once balance is achieved I set the saturation to around 1.25.

Sorry, no advice on Deconv - never do it in CCDStack.

Cheers, Marcus
