750详情_04

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!

EAF连线细节

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!

    Why is the Celestron C6 not supported? All that would be needed is a shorter bracket and a coupler matching the OD of the focuser.

    I have two ASIAIR plus, which I purchased during the test version, and an older type 12v EAF①②.
    Recently, I purchased another ASIAIR plus and ASIAIR mini.
    When I connected EAF ① and ② to the plus and mini that I purchased this time, EAF only recognized ①, and ② did not recognize either plus or mini. By the way, since the controller works in this state, the EAF itself is normal, and the plus that I originally had recognizes both EAFs ① and ②. I’ve tried various things, including changing cables, but is there anything else I can try?

    Can the AEF be mounted directly on the William Optics Red Cat 61 RP focuser? If not, does it require 3rd party adapter like the Red cat 51 and 71 with helical focusers?

    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?

    Thank you

    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?
