ZWO EAF-N Electronic Automatic Focuser (EAFN)
ZWO EAF-N Electronic Automatic Focuser
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. Available in two versions: EAF and EAF Pro — to suit different user needs.
The second generation of the beloved EAF, the EAF-N, now 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.
5 kg（11.02lbs） High Load Capacity
Astronomical observation equipment often requires the use of various heavy components. he 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 ASlAlR, 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
Hand Controller
The EAF hand controller is made of high-quality, eco-friendly ABS material to ensure a comfortable grip. The hand controller provides an easy method of focusing the telescope, featuring IN and OUT buttons, allowing for smooth manual focusing without relying on a computer or smartphone. This design also minimizes subtle vibrations during operation, helping to maintain precise focus. A “must-have” option for EAF users!
