Thanks guys, I think it's one of my best of the red planet!
Robert, i'm not 100% sure on the technical explanation, probably should wait for bird to chime in.
I use it because other (better) planetary imagers (such as Bird) use it. I bring my RGB image into AstraImage, use "Process->Split Colour Planes" which splits it into separate RGB images (useful on its own), then do a LR deconvolution on each plane, and then use "RGB combine" to bring them back together. It seems to make my image sharper without introducing too much extra grain.
