Product Description

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.

Compared to the old version of the ZWO EAF focuser, the main change of the 5V EAF is to eliminate the need for a 12V power supply port. Now you can directly connect it to your camera, laptop or ASIAIR PRO via the USB 2.0 port and use a cable for both data transmission and power supply! This makes the cable management much easier, as well as reducing the need for additional power outlets.

The innovative decorative pattern on the EAF is inspired by the changes of Airy disk during focusing showing how the focusing curve gives a local minimum at best focus – giving an easy explanation on how the EAF works just with a glance on the cover!

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 in the future.
