Just goes to show ...
I had a final video lurking from my last session. I'd discarded it because cloud came over and, whilst I picked a gap in the clouds to shoot, I was pretty sure it was/would be affected since cloud occluded the last few seconds. Well, leason learned: stack every video, because that turned out to be the best one!

slightly more aggressive sharpening and a little more post-processing.
Advice welcome. Particularly, as I'm still faffing about with processing, if any of the "master planetary imagers" have some tips, I'm all ears.
