Hi Phil,
Yes, these craters, to get them right, seem to be a lot of work. Alan and I have similar seeing many times, I think. Much of the time, it can be good but the upper level winds will tend to morph images, sometimes severely. Luckily, with most of the craters, the morphing this time has been only moderate so with muliple area processing or distor (Iris), they seem to be coming out ok. Thanks for the nice comment and, yes, I was uncertain which crater that was actually. I spent about 90 min looking over the Lunar Atlas but just took the best guess. I'll take a look at Eratosthenes and thanks for the heads up!
Eric

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.
