After downloading and installing Registax 4 I just had to give it a go. Here is an image of Clavius from 9th May 2006. I just set everything to auto in Registax and used the new Multiple Alignment Points (MAP) function and it did a pretty good job.
Image acquired with a C9.25, x2.5 Powermate and Philips ToUcam 840K. Processing in Registax was limited to Wavelet setting 1 = 25
Thanks guys. I should have mentioned that the original avi was captured during a spell of very good seeing, so the final result is more to do with the seeing rather than R4 in this case. I must dig up the R3 version and do a comparison.
I'm not one for many lunar images (usually prefer it to not be visible) but occasionally there are images of the moon that really grab me - this is one, it really feels like you could reach out and touch it. Very nice composition, cropping etc to create that effect together with the sharp high resolution image.
