Great image of a very difficult subject to image.

Kirk -

Very nice work to capture the rille at this sun angle. Thanks for posting it.

Hello Everyone,

Thanks for the kind comments. I have been trying to catch the rille and craterlets for some time. I finally got them. The seeing was not quite good enough for f/20, and I had some wind. Therefore, this AVI had to be processed 10 times, each time I put the alignment box on a different part of the image to get maximum sharpness in that region. I then took all 10 processed images and cut them apart to get the best pieces. I then assembled everything into the image I posted.

This is the first time I have used this technique, but it works quite well if you don't mind running RegiStax all day just to get one image.

This is am amazing image. The detail is just superb! I too am interested in how you processed the image in pieces and reassembled it. I think many of us would be interested in your technique.
