I  have the Williams 6aIII on the GT 71 scope and an asi 294 camera.
How do you change the camera rotation if needed to match a previous shoot without
messing up the back focus by turning the ring on the reducer?
Am I missing something?
Wont I screw up my flattened field by adjusting the ring?
How else do you turn the camera?

I use the William Optics Rotator.  Relatively inexpensive and as long as you don't need full automation on it it works well.

I use a Blue Fireball M48 rotator between the flattener and my camera. There are a few third-party brand manual rotators that you can get for M48 or M42 threads (depending on your camera and other adapters).

You might not notice a relatively small rotation of the flattener, but I think it’s probably best to leave it alone once you have it set the way you like it.

I just purchased the William Optics 63mm Manual Rotator and use it in front of the reducer. The 360* markings with "set arrow" make it easy to line up a previous image angle.
