ZWO EAF Pro: Wireless Electronic Focusing with Built-in Battery

The ZWO EAF Pro brings a new dimension to focus control in astrophotography. Designed to offer greater freedom and comfort, this electronic focus motor combines a built-in battery, Bluetooth 5.0, and manual control buttons in a compact and rugged housing. This allows for precise focus control without requiring an external power source or permanent wiring.

Thanks to its wireless design, the EAF Pro can be easily integrated into a modern astronomical setup. In particular, it communicates with ASIAIR and ASIStudio, as well as with other compatible platforms, while allowing users to adjust settings directly from the motor itself.

Fully wireless focusing

One of the main advantages of the ZWO EAF Pro is that it operates without an external power source. Unlike a conventional focus motor, which requires a constant connection to a power source, the EAF Pro has its own built-in rechargeable battery.

This design significantly reduces the number of cables needed around the telescope. As a result, the motor can be mounted directly on the focusing system while maintaining a clean, uncluttered setup. This lack of cabling is particularly advantageous for portable setups, where every additional component can complicate the assembly process.

Bluetooth 5.0 also allows for a wireless communication with compatible devices and platforms. This gives astrophotographers greater freedom when preparing for and controlling their sessions.

Up to seven nights of battery life

The built-in battery allows the ZWO EAF Pro to reach up to seven nights of continuous battery life. This long battery life allows you to use the motor for several sessions before you need to recharge it.

This feature is particularly valuable for astrophotographers who regularly transport their equipment or set up sessions far from a power source. The EAF Pro can thus operate independently throughout the night, without the need for an additional power cable.

Manual control directly on the motor

The ZWO EAF Pro does not rely exclusively on an app or a computer to make adjustments. It features built-in control buttons allowing you to adjust the focus position directly from the camera.

This feature is particularly useful during the initial setup or when a quick adjustment is needed during a session. Even after you've mounted the motor on the telescope, you can perform Precise adjustments directly on the EAF Pro, without having to use an external device every time.

The combination of manual control and wireless operation thus offers great flexibility. The user can choose the method best suited to the situation, whether it involves direct adjustment or fully automated control.

Compatible with ASIAIR and ASIStudio

The EAF Pro integrates easily into ZWO's software ecosystems. Its wireless connection makes it possible to use it with, among other things, ASIAIR and ASIStudio, as well as with other compatible platforms.

This compatibility makes it possible to integrate the motorized focusing system with the rest of the astrophotography setup. Using a compatible software interface, it is thus possible to control the focusing system alongside the other equipment in the setup.

The wireless operation also helps simplify cable management. This allows the EAF Pro to be integrated into an automated system while maintaining a particularly tidy setup around the telescope.

A compact and rugged design

Despite the inclusion of a battery, a Bluetooth system, and manual controls, the The ZWO EAF Pro retains a compact design. Its rugged housing is designed to accompany astrophotographers during their various sessions, whether at home or on the go.

Its compact design makes it easy to integrate into various types of instruments without significantly increasing the size of the optical train. It is therefore a particularly attractive solution for users seeking a motorized focusing system that combines accuracy, autonomy, and ease of use.

Be sure to check for mechanical compatibility

For telescope users Takahashi, C8 and C11, special attention must be paid to the selection of the flexible coupling. The new EAF and EAF Pro are not not fully compatible with the 5-mm flexible coupling.

To ensure proper installation, it is therefore We strongly recommend using the 4-mm flexible coupling with these configurations. It is important to verify this compatibility before installation to ensure that the motor operates properly.

More Power with the New Engines

The new EAF engine offers a increased torque, which requires more electrical power. This characteristic must be taken into account when pairing the motor with certain ASIAIR controllers.

The power requirement exceeds the USB output capabilities of some older models. The new EAF and EAF Pro are therefore incompatible with the first generation of ASIAIR as well as with the second generation of ASIAIR Pro.

To ensure stable operation and make the most of the engine's capabilities, it is recommended to use a new generation of ASIAIR tailored to his dietary needs.

An ideal solution for modern astrophotography

By bringing together built-in battery, Bluetooth 5.0, manual controls, and wireless control, the ZWO EAF Pro offers a particularly convenient experience. It allows for motorized focusing while eliminating many of the hassles associated with cables and external power supplies.

The ZWO EAF Pro offers a particularly comprehensive solution for astrophotographers who want the benefits of motorized focusing without the usual hassles of wiring. Its built-in battery that lasts up to seven nightshis Bluetooth 5.0 and its control buttons make it easy and flexible to use. Compatible with ASIAIR and ASIStudio, while still being controllable directly from its housing, it integrates seamlessly into modern setups. Compact, rugged, and self-contained, it offers a particularly convenient focusing solution for both stationary and mobile astrophotography sessions.
