Hi Sam,
Just asking if you are still considering developing a camera field rotator? I've got a 15.92" f/4.1 dobson telescope with Alt/Az GoTo system (Servocat/Argo Navis). I will be adding your ASI294MC Pro camera, as soon as it becomes available. Initially, my plan is to use for EAA observing, short exposures, but ultimately, I'd like to try longer exposures.
thanks
jim
