The Baader Steeldrive II is a high precision, temperature-compensating focus motor for Diamond Steeltrack focusers, with a toothed belt drive that can support heavy loads up to 8kg.

The aim of the development of the Baader Steeldrive II was not simply yet another motor focuser, but a complete platform which can adapt to the individual needs of amateur astronomers. That's why the "brain" of the Steeldrive II is not located in the tiny housing of the motor itself, but in a separate controller which also provides a keypad for manual control.

The Steeldrive II consists of a motor unit, which is connected with a timing belt to the focuser's slow-motion-control to work without backlash, and of a control unit with the electronics, which also doubles as hand control.

You can connect up to two temperature sensors at the same time, one on the motor unit and one on the control unit. One sensor is included with the Steeldrive II to compensate the drift automatically, if there are large temperature differences.

The motor is designed to move to a saved position with highest precision if it is used together with the homing sensor – even if it has to move several kilograms over the complete travel of the focuser!
