Thanks Rob, I love the many faint rilles to the left and below aristarchus.
For MAP processing, I just keep going until i've eliminated all (or most) of the soft areas. I mainly concentrate on the "features", or where there's high contrast areas and something for registax to align on. I can't do it on the mare's for example, as registax just can't find enough contrast to lock on to, especially with the bad seeing. I have to click "ignore" sometimes 20+ times while it's trying to align as it can't find the feature.
I use a 128px alignment box, and my tracking is not very accurate.. so sometimes my final image is made up from several avi's which cover the broader area.. I can't keep the same area in the FOV for long enough, usually, which means the edges don't have much data and end up with artifacts after sharpening..
The high-pass filtering is in photoshop - i'm not sure what the equivalent is in other tools. I duplicate the layer, and then on the duplicate I do a "Filter -> Other -> High pass". I use a value of about 2.5 to 3, but that can change depending on the image.
I then set the blending mode to "hard light", which usually overprocesses/oversharpens the image. So I change the opacity of that layer to 20-30% (personal taste), so only some of the sharpening is revealed.
Once happy, I then flatten the image and save for web.
