ZWO EAF-5V - Electronic Automatic Focuser

Introducing 5V EAF, the upgraded version of the original ZWO EAF. This electronic focuser enables precise, dynamic focus control for planetary and deep-sky imaging.

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 5V EAF 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 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 5V EAF:

Standard Version: EAF body, flexible coupling, motor bracket, USB2.0 cable.

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

You could purchase the standard version first, and then buy other accessories to upgrade.

The casing of the hand controller uses environment-friendly ABS material. It has a 3.5mm female socket. You will have a very comfort grip when you touch its ergonomic design!

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!
