The new generation of ZWO EAF continues the brand’s signature minimalist design, featuring a robust metal housing and precise angular lines — a perfect fusion of form and function. EAF features a more universal Type-C interface for broad compatibility and easy installation.

Micron-level Positioning Accuracy

The ZWO EAF integrates a high-precision custom stepper motor with compact yet powerful performance. Featuring a 1:128 reduction ratio, it provides the motor with strong torque and precise control capabilities, achieving micron-level positioning accuracy. Each rotation responds precisely to commands, ensuring accurate and reliable focusing.

5kg High Load Capacity

Astronomical observation equipment often requires the use of various heavy components. The ZWO EAF, despite its compact size, can support a high load capacity of up to 5kg（11.02lbs）, as rigorously tested in ZWO Laboratory. Its powerful performance ensures stable operation of a wide range of equipment, meeting diverse observation needs.

More Universal Type-C Interface

The EAF is an upgrade from the previous version, with its interface upgraded from Type-B to the more universal Type-C. Users can power the EAF directly via a Type-C connection to a camera, computer, or ASIair, it also supports wired communication via a Type-C interface. Simplifying cable management and reducing power load.

Extensive Software Support

EAF supports both ASCOM and INDI protocols, making it compatible with a wide range of astrophotography software, including:
ZWO-developed platforms: ASIStudio and ASIAIR APP
Third-party software: SharpCap, FireCapture, Maxim DL, The SkyX, SGP, Nebulosity, and more. Also compatible with third-party focusing software such as FocusMax
