derotation vs singl video portion stack

[Fedele]

The image you see is taken from the same serie of videos in diffrent way. 
The first on the left is the derotation with Winjupos of three videos. It represents the best that can be obtained from these three videos with derotation (apart from the choice of different brightness, color and contrast between the two images which I ask you not to consider).
The second on the right is the classic processing with Astrosurface of just one of these films (the one least affected by seeing), from which a short, smaller portion of best seeing was extracted.

Certainly looks tome like extracting just the best frames from the best imaging run has produced the finer detailed image.

That's an excellent comparison and goes to show that derotation of inferior data can spoil a better single result, something the we have to be aware of in processing.

Thanks for this ... thought provoking !
