Hi Eric,

Great looking Archimedes!  Sounds like a lot of work but worth it to obtain such a great image.  I wish I had the aperture to capture the fine details.  Also, the second image shows a lot of details and appears to look a lot like Eratosthenes. :-)  15000 frames, WOW.

Hi all,

Here is the final version of Archimedes:

The final version is the image on the right.  Thanks again to Alan for that neat little tip for helping bring out the crater floor. 

Here is Aristillus:

Lots of fine features here.  Contrast in the individual frames was poor (due to very low light/ high gain at capture) and caused alignment difficulties, so I distorted each frame to a reference using Iris.  This helped cut the turbulence about in half.
