I hate to rain on your parade. If your mounts polar alignment is not perfect any guide scope that is not colinear with your imaging scope will cause rotation in sequential images.

I have had fun proving this by establishing where my guidescope was and watching the inevitable rotation around the point where my guide scope was pointed in my imaging system.

I used to see this as a bonus as the noise would be smoothed out with stacking.
