Hi Allan, the only guide camera is the lodestar on a pick up prism. It's behind the AO which is only a big 10mm piece of glass and in front of the imaging camera which has the Ha filter on it. The lodestar takes a picture of a guide star 5 times per second through the glass plate and the glass plate tilts to recenter the star when it moves. When the star goes out of the tilt range of the glass plate, then the mount is bumped into guiding mode to recenter the star then falls back into tracking.
