I designed it this way so the bearings would overlap the mirror box. This prevents a possible rotational vibration mode from occurring. This next image shows a Kydex baffle in place over the top of the mirror box. This provides a tighter baffle for the primary mirror and minimizes reflections from the top of the mirror box, improving contrast. This is what the scope looks like when it is disassembled for transport.
Most pieces fit nicely into the rocker box.
This is also a good view of the rocker box. This is much stiffer than my earlier rocker boxes. It has five improvements that increase stiffness. The first is that the sides are shorter because I used larger bearings to support the tube assembly. Second, and probably most important, are the gussets extending along the back sides.
