ZWO Electronic Automatic Focuser EAF Pro (86543)

The ZWO EAF Pro is an electronic automatic focuser designed for precise and dynamic focus control, whether you are capturing planetary or deep-sky images. It is compatible with most telescope focusers available on the market.

This focuser works seamlessly with all capture software supported by the ASCOM platform and fully integrates into the ZWO ASIAIR imaging and control system. With ASIAIR, you can manage your imaging sessions directly from a smartphone or tablet – even from indoors.

The EAF Pro is built with a durable all-metal housing, finished in ZWO’s signature red color to match their cameras.
