Secondary mirror mount for trackball telescope

thingiverse

This is an attempt to create a duplicate mirror support for a trackball telescope, specifically Jerry Oltion's concept. The original Oltion design utilized a vitamin bottle cut at a 45-degree angle. It prints in two pieces, which should be snapped together to form a ball-and-socket joint. Then insert two 3"-long 8-32 screws through the long holes to contact the bottom of the mirror support surface, and attach one small spring to provide restoring tension between the mirror support surface and the main block. Moving or retracting the screws allows the tilt of the mirror support surface to be adjusted in two directions to properly align with the eyepiece. The main block includes two curved holes set at right angles, allowing two wires to be threaded through. These are for attaching to the interior of the secondary cage, forming the "spider" mount. This is a work-in-progress, and I will add photos of the part fully installed in a trackball telescope once they're available.
