Hi Dave,
to IceInSpace! That's a great image for the altitude, very detailed.
I do think though that it's a bit overprocessed in the attempt to bring out more detail.
What processing did you do?
Can you post a version that's straight after stacking, without any wavelets etc?
Also, only 200 frames is quite low for what looks to be pretty good seeing. You could try stacking 400-600 if they are all pretty good quality and you'll get a smoother result.
