Mounts:

Upgrade or replace your original factory mount. Corrects the fast/touchy motion (see our fix) of the OEM "lazy Susan" azimuth assembly by using Teflon and preferred laminate, resulting in buttery motion with sure smooth starts and stops. Constructed using 18mm birch plywood to provide long lasting strength with light weight ruggedness.

This is a standardized design, no changes allowed. We will ask you to confirm a few simple dimensions to confirm your telescope tubes fits.
