I am considering adding a camera support bar to my 10" EQ 1120mm fl Newt for long focal length projection magnification. Although I have a simple design figured out, I was wondering what if one had done something similar and had any experience based tips or other suggestions. Basically, the a right-angle is inserted in the focuser, sending the optical path back to the rear of the scope. Then a barlow is used for negative projection, up to 300mm to 400mm long. This is intended to be used for projecting longer focal lenghts during astrophotography than what can be had by simply projecting "up" the axis of the focuser. - Canopus56 (Kurt) __________________________________________________ Do You Yahoo!?
