The ZWO Standard EAF (Electronic Automatic Focuser) Pro is a powerful upgrade for imagers seeking precise and repeatable focus across temperature shifts, filter changes, or extended exposures. Designed for compatibility with most popular telescope focusers, this robust unit allows you to achieve sharp focus hands-free using ASIAIR, ASCOM platforms, or dedicated hand controllers.
With stepper motor precision, backlash control, and temperature probe support, the EAF Pro is ideal for automating focus routines in both planetary and deep-sky astrophotography. It integrates seamlessly with ZWO's ecosystem, enabling full control through your existing ZWO setup, including support for autofocus routines in third-party software. Whether you're capturing long exposure galaxies or high-frame-rate planetary video, the EAF Pro ensures you're always perfectly dialed in.
