skywatcher telescope "micro" focuser

A simple way to get a very accurate focus on my old skywatcher 200x1000.
The focus is quite stiff and there is no microfocuser, With this thing you get an accuracy multiplied by 10 and a torque to apply divided by 10 thanks to the lever rod.

just insert a 5 mm carbon rod (or aluminum) into the hole of the cap, push the cap around the knob et voilà !

Very easy to remove too in case you change your eyepiece and need long focus range...
