Thanks for your designs.

In my case the main goal was to design a system that could be easily dismantled, as I have to travel each night to a dark side. Instead of using a gear profile I designed a piece with pockets. To avoid any backlash a small screw can press both pieces.

But your design has given me some good ideas to solve the manual focusing. I have a separate Pegasus Astro Controlller, with a knob to move the focuser without a computer.

I attach three pieces: the telescope side (with the four pockets), motor side and the main piece that connects the motor with the main flange, should Jim need to assemble/disassemble the motor each night.

It has not been tested yet on field.
