When you are setting up to do the de-rotation, look in the Options tab above the workspace window which has the controls for dealing with moons. Best if moons are off the disc but if your image measurement is accurate enough then it works for moons or shadows in transit as well.
That did the trick, thank you!
What are the image measurement optimization options...should they also be checked?
There is a masking radius value...it can be set low actually, but it appears that it merely cuts out one of the moons in the image.
So, to sum up, this works for moons outside disk, does not work for transit and does not work for shadow transits. Derotation of videos neither.
