After getting turned on to Tony Gondola's lunar processing workflow, I thought I'd give it a shot.
Here's my first attempt at a six-zone (3 col. x 2 row) stack & mosaic, followed by high-pass filter sharpening.
I enlarged my original 640x480 .mov 150% in Quicktime Pro player and aligned & stacked on six areas in Keith's Image Stacker. I did one pass of wavelets, and am afraid I used to much.
I used PS CS2 to crop the six images and automerge them back into one. I made three passes with the high pass filter at 6, 3 and 1 pixel using Tony's settings.
I reduced the image back to 640 x 480 and despeckled. Alan Friedman's safe from me for a while, but I can see great potential here.

I love the original, it's closer to what I saw in the eyepiece.

I like the original shot better too.
The second is overprocessed as you said. It is so easy to over do wavelets on the Moon. I've found I barely go past 3 on # 1 wavelet. Does look like a very promising shot!

I use high-pass filtering on my lunar processing, but only on a duplicate layer and I only make that layer with 20-40% opacity so only some of it shows through.
In my opinion the second shot is overprocessed and not natural looking.
I've also had success doing LR deconvolution on my lunar shots recently.

It was definitely over-processed. Here's my second attempt on a different shot. I used 5 zones--the 4 corners and one on Copernicus.

I'm thinking, since the Photoshop Photomerge only works with 8-bit images, I should go ahead and high-pass, sharpen & levels the individual zones before I merge them. It would make sense to not throw data away until the very last instant. It'll be more time consuming, and require careful notes to process all of the zones the same, but it's certainly do-able.

I had thought about doing it that way, too. I get zone boundary artifacts, though. I merge cropped bmp's output from registax, then do the sharpening and noise reduction.

One last shot of Copernicus. Nine zones and probably too much sharpening, but remarkably little noise for only 123 frames stacked.
