(SD II) motor focuser. This manual describes ins-
tallation and operation of the motor unit.

The Baader Steeldrive II motor focuser consists
of the motor unit and the controller. Both units
are also available seperately. You always
need one controller to operate one
motor unit. But you can use one cont-
roller with several motor units one at a
time - you only need to plug it into
the motor unit which you want to
use.
