ZWO EAF-N Autofocuser – USB-C Upgrade

Designed for precision astrophotography, the ZWO EAF-N brings effortless, repeatable focus to your imaging setup. This 2025 upgrade introduces a USB-C port for faster and more reliable data transfer, along with improved cable management to suit modern telescope configurations.

Compatible with ASIAIR, ASCOM, and INDI systems, the EAF-N integrates smoothly into ZWO’s ecosystem. With a 5kg payload capacity, it supports heavy imaging setups - delivering consistent, automated focus whether you're capturing distant galaxies or high-resolution planetary images.

For even more flexibility, the ZWO EAF Pro version adds Bluetooth connectivity, manual focus buttons, and a built-in battery, enabling focus adjustments without the need for an external controller.

Specifications

• Connectivity: USB-C, 3.5mm port for hand controller or temperature sensor
• Protocols Supported: ASIAIR, ASCOM, INDI
• Payload Capacity: 5kg

Whether you're imaging from home or under dark skies, the ZWO EAF-N delivers sharp, precise focus - night after night.

Compatibility Notice: Due to the increased torque of the new EAF motor, higher power input is required. This exceeds the USB output capability of earlier ASIAIR, making it incompatible with the first-generation ASIAIR and the second-generation ASIAIR Pro. For stable operation, it is recommended to use the new-generation ASIAIR.
