-All-thread connected to a stepping motor is used to move the mirror.
-Note the magnet (on the black) there is a reed switch inside the stepping motors mount, when the motor gets close to the magnet it is stopped and the stepping motor counter can go to Zero.
- the stepping motor can pan out to 40,000 steps and tilt out 21,000 steps
