    Why aren't you using a high magnification sextant telescope with suitable exit aperture filter?
    You don't get high with Hughes. It's  2X for a Mk2 periscopic or 2.5X for a Mate's 3 Circle.  There is a 5x with the Mate's for horizontal work, but it's like a pea shooter.  I don't think it would throw much of a projection, but I'll give it a try.  I don't want to start looking through it however well filtered. In any case, the star gazers talk about using 60X.  DaveP
