Wouldn't this require a CCD with a convex curved surface? The designs for
Schmidt cameras I've seen used a vacuum system to mold the film to a curved
shape to follow the surface of focus. Maybe the CCD would be small enough
that "flat" would be a pretty good approximation to the desired curve over
that area. I wonder how far back you'd need to move the primary mirror to
obtain focus at the secondary location, and would the LX200 move back that
far without modification? (Sorry to just be raising more questions without
providing any answers...) Also you'd have to deal with routing the CCD
wiring across your optical path.
