ZWO EAF Electronic Automatic Focuser 5V

Introducing ZWO 5V EAF – Electronic Auto Focuser ( Astrophotography Gadget ), like its previous version, enables precise, dynamic focus control for planetary and deep-sky imaging, while only connected to a 5V USB-port.

The primary difference between the 5V EAF and the older ZWO EAF focuser is the absence of the 12V power supply connection. Now, you can connect it straight to your camera, laptop, or ASIAIR PRO via the USB 2.0 port and use the same wire to send data and power. This makes it much easier to organise the cables and cuts down on the need for extra power outlets.

The unique design on the EAF is based on how the Airy disc changes as you focus. It shows how the focusing curve has a local minimum at best focus. Just by looking at the cover, you can tell how the EAF 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.
