用于 SCT 和 EdgeHD 的 Celestron 调焦马达为 Celestron Schmidt-Cassegrain (SCT) 和 EdgeHD 望远镜光学筒提供电子调焦。安装调焦马达后，您可以使用望远镜的手动控制器或计算机将天体对焦清晰、精确，而无需使用调焦旋钮。调焦马达非常适合想要调准焦点的视觉观察者（尤其是那些灵活性有问题的人），也是天文成像师的必备配件。安装电动调焦器后，天文成像师不再需要靠近望远镜来对焦图像。结合对支架和摄像头的计算机控制，调焦马达使成像师能够从后院天文台甚至数百英里外的望远镜远程收集数据。作为额外的好处，端口盖可以在不使用时保护端口，并且由于采用系绳设计，盖子不会丢失。

兼容光学筒

调焦马达与 2006 年以来生产的所有 6 英寸至 14 英寸口径的 SCT 兼容。它与 5 英寸 SCT 或更老的型号不兼容。它与所有 EdgeHD 光学管、8 英寸 Rowe-Ackermann Schmidt 天文照相仪 (RASA)、36 厘米 RASA 和 7 英寸 Maksutov-Cassegrain 兼容。它也可以与 11 英寸 RASA 一起使用，但需要RASA 11 的调焦器改装套件。

电源选项

有三种方式可以为您的 Celestron Focus Motor 供电：

1. 使用 Celestron 电脑化支架时，您可以使用随附的 AUX 电缆通过支架为对焦马达供电并进行控制。这样可以通过支架的手动控制器（NexStar+ 或 StarSense）或计算机进行控制。
2. 如果您不使用 Celestron 支架，您可以通过计算机 USB 端口为对焦马达供电并控制对焦马达。您需要用户提供的 USB A-B 电缆。
3. 您也可以选择使用插入电机电源插孔的外部 12V DC 电源。

兼容软件

Celestron 提供免费的 Focuser Utility 程序用于计算机控制。Celestron PWI 软件也可以控制对焦马达。要使用第三方对焦器控制软件，需要 ASCOM 驱动程序。

规格

ZWO’s legendary Electronic Automatic Focuser (EAF) platform gets a smart, modern update with the new EAFN. Designed for astrophotographers who value precision and simplicity, the EAFN retains the solid mechanical design of the original while introducing a USB-C connection and micron-level focus accuracy for today's imaging demands.

It’s the perfect fit for users who want a clean, efficient setup without sacrificing performance.

What’s New in the EAFN:

• USB-C Interface: Easier to connect in the dark, more robust, and in line with modern gear.

• High-Precision Focusing: Delivers micron-level step resolution for ultra-fine focus control.

Tech Specs:

• Connectivity: USB-C, 3.5mm port for hand controller or temperature sensor

• Supported Platforms: ASIAIR, ASCOM, INDI

• Payload Capacity: Up to 5 kg

• Status Indicator: Integrated LED

The ZWO EAFN is a sleek and dependable option for both new and experienced imagers looking to enhance their focusing precision—without the extras. Reliable, accurate, and easy to integrate, it’s everything you need and nothing you don’t.

ZWO EAF Pro – The Next Evolution in Electronic Focusing

ZWO’s best-selling Electronic Automatic Focuser (EAF) just got even better. The new ZWO EAF Pro builds on the rock-solid performance of the original by adding Bluetooth wireless control, a built-in rechargeable battery, and onboard manual focus buttons—all in the same compact form factor. It’s the perfect upgrade for astrophotographers looking to cut down cable clutter and gain more control at the scope.

What’s New in the EAF Pro:

• Go Wireless: Integrated Bluetooth and a 2500 mAh battery let you focus remotely without a tangle of cables.

• Streamlined Upgrades: Shares the same mounting footprint as the standard EAF (5V bracket compatible), so switching over is simple.

• Manual Control Onboard: New physical Focus In/Out buttons allow fast and precise adjustments at the scope—no need to reach for your phone or controller.

Tech Specs:

• Connectivity: Bluetooth, USB-C, 3.5mm port for hand controller or temperature sensor

• Battery: 2500 mAh rechargeable

• Supported Platforms: ASIAIR, ASCOM, INDI

• Hardware Controls: Power switch, Focus In/Out buttons

• Payload Capacity: Up to 5 kg

• Status Indicator: Integrated LED

Whether you're fine-tuning critical focus for deep sky imaging or just want fewer cables in the dark, the EAF Pro is a smart, streamlined upgrade for any astrophotography rig.

• The Series-5 focuser is a large capacity focuser for use with Alt/Az, or equatorially mounted systems.
• The focuser is capable of lifting 40 lbs (18 kg) with a travel range of  0.6-inches (15,200 microns).
• The Series-5 focuser can be stacked with the Series-5 rotator for a complete focusing rotator solution (combined 2.78″ of occupied backfocus).
• Occupies only 1.675” of backfocus.
• 464.4283 encoder counts per micron
• Controlled via PWI4 software for autofocusing and optional field de-rotation (if using an Alt/Az mounted system).
• Requires the Series-5 Controller.
• Compatible with the DeltaRho 350 and RC700 telescopes.

• The Hedrick focuser designed by PlaneWave is a heavy duty no-slip focuser capable of handling an imaging payload of up to 20lbs.
• Occupies 3″ of backfocus with the focuser fully racked in, and 4.2″ when fully racked out.
• Focuser travel range of 30mm (30000 microns/1.2″)
• The focus tube runs on 5 bearings and is driven by a leadscrew so there is no chance of slipping.
• Focus may be automated through a computer using PlaneWave’s EFA Kit and PWI3 software.
• The focuser comes with pre-installed motor that can be controlled with the EFA hand controller or PWI3 software.

Introducing the New ZWO EAF 5V , this electronic focuser, like its previous version, enables precise, dynamic focus control for planetary and deep-sky imaging, while only connected with 5V USB.

No more need for independent 12v Power when it can run from a USB power source.

Features:

1. Highly integrated design
2. Support ASCOM platform and various ASCOM-compatible third-party software
3. Support INDI
4. Support original software such as ASIAIR and ASIStudio
5. Support automatic focusing for DSO imaging
6. Support handle controller and manual focusing
7. Support temperature sensor
8. USB HID device and drive-free
9. Stable and durable

Compared to its old version, the main change of ZWO EAF V5 is to remove the 12V power supply port. Now you can directly connect it to your camera, laptop or ASIAIR PRO via the USB 2.0 port & cable for both data transmission and power supply. This would not only make the cable management much easier, also effectively reduce the supply pressure.

The innovative decorative pattern on the EAF is inspired by the changes of Airy disk during focusing and the focusing curve, which makes it clear at a glance how this focuser works.

There are two variants of the ZWO EAF V5:

Advanced Version: EAF body, flexible coupling, motor bracket, USB2.0 cable, hand controller, temperature sensor.

The hand controller provides an easy method of focusing the telescope, featuring IN and OUT buttons, a 2-line display, slow and fast speed rate control.

A “must-have” option for EAF users!
