ZWO Electronic Auto Focusser (EAF)

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

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 driver-free
9. Stable and durable
   Compared to the old version of the 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.

   The casing of the hand controller uses environment-friendly ABS-material. It has a 3.5mm female socket. The design aims at giving you the best ergonomic grip, so that you focus (pun intended J ) on capturing images!

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

   A “must-have” option for EAF users!
