Starlight Instruments Stepper Motor for Focuser Boss System

This motor is designed specifically for the Starlight Instruments 2" Focuser Boss System. While it is compatible with various telescope types—including refractors, reflectors, and Schmidt-Cassegrains—it requires that your focuser is already set up to work with the Focuser Boss ecosystem.

The primary benefit is precision. By replacing manual focusing with a stepper motor, you eliminate the vibrations caused by touching the telescope, allowing for much finer, repeatable focus adjustments that are essential for sharp astrophotography.

Yes, this motor requires a 12V DC power source. You will need to ensure you have a compatible power supply or field battery that can provide consistent 12V power to the Focuser Boss controller.

Installation is straightforward if you are already using a compatible Starlight Instruments focuser. It is designed to integrate seamlessly with the Focuser Boss system, though you should ensure your specific focuser model is listed as compatible before purchasing.

While it is a game-changer for astrophotography, it is also excellent for visual observing. It allows you to achieve perfect focus without shaking the telescope, which is particularly helpful when using high-magnification eyepieces.
