[mill (Martin)]

I made a focusser for the scope i got so kindly from avandonk (Bert).
It is made from a small motor that was driving a mirror for a laser and connected to a MCLennon gearbox (25/1).
The gearbox in the motor is about 10/1 so the focusing is very precise.
The two round bits holding the motor assembly are button batteries that were exactly the right height.
The coupling is made from the Losmandy worm coupling.
