Product Description

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:
- Highly integrated design
- Support ASCOM platform and various ASCOM-compatible third-party software
- Support INDI
- Support original software such as ASIAIR and ASIStudio
- Support automatic focusing for DSO imaging
- Support handle controller and manual focusing
- Support temperature sensor
- USB HID device and driver-free
- 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!

I have an old (bought used circa 2007) C9.25 with a Feather Touch Micro Focuser installed to replace the original focus knob. Does the “ZWO EAF Bracket for Celestron C8 and C9.25” work with that or is this for an add-on focuser? ZWO’s compatibility list for the C9.25 states, “You will need extra focuser for this. ZWO EAF Bracket for Feather Touch Focuser only compatible with the Feather Touch focuser on Celestron 8″ SCT/RASA, 9.25″ SCT and the 11″ SCT/RASA.” The High Point Scientific website has this description for the “ZWO EAF Bracket for Celestron C8 and C9.25”: Using this bracket allows you to bypass the FeatherTouch focuser completely.

For Celestron EdgeHD 9.25″ and the Celestron .7x Reducer Lens for EdgeHD 925 # 94245 you will have to file down the rounded end of the Bracket that mounts to the Telescope Focus. If not you cannot screw on the Reducer and when you have the Reducer installed you cannot mount the bracket to the Telescope Focus, 1/16 of an inch to big.

What coupler is compatible with a Takahashi Epsilon 130D? This link, https://www.yuque.com/zwopkb/hardware/eaf-support-list, provides a link to a video showing a ZWO EAF attached to an Epsilon 180D, but assuming they use the same coupler, there’s no info, just a video on Facebook.
Thank you.

The EAF temperature sensor gives noisy readings from sample to sample (up to +/- 0.5 deg). Would be nice if there was an “averaging n samples” feature in the driver to smooth out the T values… Any chance this could be implemented?

Hi ZWO
Do you sell a flexible coupling 5-6mm with a smaller external diameter? 17mm would be good.
Telescope: Sky-watcher Evolux 62ED focuser housing is slightly too small for the 19mm flexible coupling.
Thanks in advance

I’m using the EAF first version on my Pentax refractor, works great. I ordered a new version for my Vixen VCL200. I see that it is possible to connect to the focuser. It looks like a special bracket is needed. Can I get this from you or do you have a drawing/spec sheet for the one pictured on your site?
