Thanks Trevor! Yes de-rotating stacked images certainly produce a smoother image. Provided seeing is consistent you can be much more severe with selecting frames. I think I used 4 images each consisting of 1000 frames from 10,000 so the de-rot image contains 4000 frames. Individually the 1000 stack images were way too noisy as gain was about 85%.
I've yet to have much success with de-rotating avis as it seems a lot of work for little reward.
