I had another go in AS!2, this time stacking 3000 of the 9500 frames I had, instead of 100...
I had enough data that the wavelets actually did something useful this time. Lots more fine detail, and a better impression overall. Not that bad for 8" and a DSLR
Also, that Saturn above was taken when it was about 15 degrees up, so lots and lots of atmosphere in the way, accounting for the blurriness. I've retried reprocessing those clips, but there's too much dispersion to get good details in the reprocessing.
