Dennis,
You are the man when it comes to lunar shots!
I notice your images seem a lot darker than mine, which helps to avoid the burned out white patches where the sun shines on crater walls, etc which I struggle with. I usually try to keep the top end of the histogram between 1/2 and 3/4 of full scale (in K3CCDTools) to try to control this. Any tips you'd care to share to avoid overexposing the bright bits?
Thanks,
Al.
