Okay, after a good night’s sleep I managed to grab some single frame screen grabs and have shown the “Raw” and “Processed” versions for both the ingress and egress phases.
These show quite graphically the difference between "as seen" and "as processed".
The Moon’s limb really rushed up to Saturn (I was tracking on Saturn) and sometimes AS!3 would Align on Saturn, producing a stack with multiple offset lunar limb images and an aligned Saturn, and sometimes it would Align on the lunar limb and produce multiple offset Saturn images.
Cheers
