Peter I'm not sure where I heard/read it, but I remember something about if the two imaging systems are not orthogonal then you well get frame shift. Particularly if they are also non-orthogonal to the mount. I experienced the same as you at one stage and just about went balmy trying to eliminate it. I also seem to remember something about even slight polar misalignment can exacerbate the problem as well.
