Image Train Isolator for GSO 10" RC or AT10RC

This picture shows a cutaway section and close up of the captioned OTA that I made in 3D Acad. The close up shows the Isolator part which couples all the image train weight to the back plate, and not to the primary mirror assembly.
It was a lot of fun and learning experience to take apart the OTA, measure everything, create the 3D CAD (with help of Ken), and make it into a complete OTA assembly. Cutting a section through the CAD let me easily see how everything was mounted, and how to decouple the image train to the primary mirror cell.
