What else do I need to use the Steeldrive II Controller?
The Steeldrive II Controller is the control unit only. To create a complete motorized focusing system, you will also need a Baader Steeldrive II Motor Unit and a compatible focuser, such as a Baader SteelTrack or Diamond SteelTrack.
Can I control two telescopes with one Steeldrive II Controller?
No, one Steeldrive II Controller can operate one Steeldrive II motor unit at a time. However, if you have two complete setups (two motors and two controllers), you can connect both controllers to a single computer and operate them in parallel using the SteelGo software.
How does the Steeldrive II Controller handle temperature changes during an imaging session?
The controller has built-in logic for temperature compensation. When used with the temperature sensor on the Steeldrive II motor unit, it can automatically make micro-adjustments to the focuser position as the ambient temperature drops, keeping your images sharp throughout a long night without manual intervention.
What is the practical difference between the "Jogging" and "Single Step" modes on the Steeldrive II Controller?
Jogging Mode is for making small, repeatable adjustments where you define the step size (e.g., for finding focus with a Bahtinov mask). Single Step Mode makes the absolute smallest mechanical movement possible, which is essential for the final, critical tweak when visually observing a planet like Jupiter at high magnification.
Do I need a computer at the telescope to use the Steeldrive II Controller?
No, a computer is not required for core functionality. You can move the focuser, set travel limits, save positions, and manage temperature control directly from the hand controller, making it perfectly suited for visual observing or minimalist imaging setups.
How would I use the Steeldrive II Controller to focus on Saturn with an 11" SCT?
For a high-magnification target like Saturn, you would first use Normal Mode to get close to focus. Then, switch to Jogging Mode for finer adjustments until the Cassini Division is visible. For the final, sharpest view, you would use Single Step Mode to make tiny nudges to the focus point until the image is perfectly crisp.
