ZWO EAFN Electronic Automatic Focuser

Updated USB-C connectivity, ultra precise focusing, and support for heavy cameras and accessories mark the EAFN Electronic Automatic Focuser from ZWO. With the ability to focus at the micron level, the EAFN will help you achieve pinpoint stars and tack-sharp planetary images in your astrophotography sessions. Compatible with a wide range of refractor, Newtonian, Cassegrain, and other optical tube assemblies, the EAFN is controlled by a USB-C connection to a computer (or ASIAIR Wi-Fi module) and can support 11 pounds including a camera, filter wheel, off-axis guider, and other accessories. It supports ASCOM and INDI drivers and compatible astrophotography software, naturally including ZWO's ASICAP products. Add the optional, separately sold hand controller and temperature sensor to make the unit even easier to operate.
