ZWO Electronic Auto Focuser with BT

This ZWO EAF Pro Electronic Automatic Focuser moves ahead of previous EAF models with USB-C connectivity, ultra precise focusing, support for heavy cameras and accessories, and its own rechargeable battery power supply. With the ability to focus at the micron level, the EAF Pro helps 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 EAF Pro is controlled by a USB-C connection to a computer (or ASIAIR Wi-Fi module) and supports up to 11 pounds including a camera, filter wheel, off-axis guider, and other accessories. Built-in Bluetooth and a new focus adjustment knob further extend the EAF Pro's capabilities.
