    Hi Tony,



    I definitely need a sketch of the proposed device to imagine it.


    Fair enough!  Reading my text again, it is not quite the model of clarity I had intended.  :-)

    Attached are CAD sketches of the layout.  The top view shows a ray diagram of two celestial bodies---the first mirror set handles the bulk of the angle, and the second set the remaining small angle.  The transparent blue frame is just a stand-in for some eventual structure.  The orange cylinder is the sighting tube or small telescope.

    Cheers,
    Peter
