Will an STXL-16200 with self-guiding filter wheel work on a Celestron C11 HD scope? Its opening at the back of the scope is around 2" and has a back focus of 146mm from the back of the flange. Not sure if a 2" image will cover the pickoff mirror for the guider.
Camera plus filter wheel and accessory ring needs 76.7 mm of back focus. So should be no problem assuming reasonable adapters.
