OK Peter, here are some screen shots of stacking and sharpening a Saturn AVI. I use a mono camera, so this is the L channel.
AS!2:

Bring it into R6 for wavelets:

The result (nice and sharp!):
I'll use the same stacking and sharpening settings for each of the R, G, B channels, but usually the L is treated differently as you take more L frames.
Combining them in gimp is another exercise.
