5kg High Load Capacity
Astronomical observation equipment often requires the use of various heavy components. The ZWO EAF Pro, despite its compact size, can support a high load capacity of up to 5kg. The weight capacity was rigorously tested in the ZWO Laboratory. Its powerful performance ensures stable operation of a wide range of equipment, meeting diverse observation needs.
Wireless Bluetooth Built-In
The EAF Pro features a built-in low-power Bluetooth 5.0 chip, enabling wireless connectivity with ASIAIR and smart cameras. It is fully compatible with ASIAIR APP, ASIStudio, and ASCOM platform software — offering flexible and cable-free focus control.
Built-in Lithium Battery
Powered by an integrated lithium battery, the EAF Pro frees you from external power constraints and enables truly wireless operation. It offers greater flexibility and ease of use to meet diverse needs.
Optional EAF 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!
The EAF Pro is Easy to Install
Note: The installation images below show the EAFN being installed, but you follow the same steps for the EAF Pro.
1. Remove the coarse adjustment knob of the telescope focuser using a suitable sized wrench.
2. Install the coupling on the telescope focuser shaft and tighten the locking screw with the 2mm hex wrench.
3. Attach the focuser body to the coupling, align the EAF Pro motor shaft flat surface with the locking screw, and tighten the locking screw using the provided 2mm hex wrench.
4. Secure the EAF Pro body to the bracket and the bracket to the matching mounting holes in the focuser assembly using the supplied M4 screws. Ensure that the bracket is flush with the EAF Pro mounting surface without any gaps, and that it is parallel to the focuser body surface.
5. Check and ensure that all the connections of the EAF Pro are secure. This completes the hardware installation of the EAF Pro.
6. For curved focusers like the one in the image above, you only need to use the original locking screws and 3 washers to secure the EAF Pro. There is a groove at the bottom of the EAF Pro bracket, and a single screw provides sufficient stability.
