Thanks for the further clarifications. In my hands, I find that derotation is giving me less of an improvement and more noisy sharpening. The best Jupiter I have are from 3ms exposures so it seems to be a sweet spot for our UK seeing. I tried to go to 1ms but the seeing wasn't of the same quality so it would be an unfair comparison. Although I am fun of Astrosurface sharpening I tend to over do it. These have not been sharpened there.
As I keep telling myself, unless I can see details during capture, there is no way to make a good image from a subpar capture. I abandoned my captures last night based on that.
