ZWO EAF Pro Launched: The Ultimate Cable‑Free Focuser Upgrade

ZWO has taken its trusted autofocus system to the next level with the newly launched EAF Pro. This latest model is designed for simplicity and portability. It removes cables, adds wireless control, and includes a built-in battery. The EAF Pro is not just a motor upgrade; it’s a complete rethink of how astrophotographers can achieve perfect focus in the field.

ZWO EAF Pro

The original EAF had a USB stepper motor. It worked well. But it needed external power and a cable. That setup often created clutter. The EAF Pro fixes that. It simplifies and modernizes focus control. The EAF Pro supports Bluetooth 5.0 and has a 2,500 mAh lithium battery. It lasts several nights per charge. You can operate it cable‑free. Better still, it runs on USB‑C when recharging. It has focus “In” and “Out” buttons built in. That removes the need for an external hand controller.

Key features

Here are some of the key features of the new ZWO EAF Pro:

Wireless control

• Connects to ASIAIR, ASIStudio, ASCOM, and INDI over Bluetooth 5.0.
• No USB cable to the laptop or imaging computer is needed.

Internal battery

• Built‑in 2500 mAh rechargeable battery.
• Enough power for several nights under normal use. Rechargeable via USB‑C.
• Great for grab‑and‑go or remote setups.

Manual focus buttons

Same motor & bracket
