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!

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!

    Hello, I connected EAF at the USB2 hub of the ASI2400MC Pro camera. The EAF is powered, but ASIAIR Pro does not detect it (the focuser icon on the top bar of the ASIAIR app screen is grey out). I don’t have any USB2 port available on ASIAIR. How could I connect the EAF so it is powered and detected by ASIAIR?
    Thank you.

    Hello,
    I have just purchased EAF for a FeatherTouch focuser. Could you, please, clarify where the 0 position should be set? Your manual addresses this information at page 22, where it reads ” near the focus of the focus of the focus holder”. This sounds like a transcription mistake. Thank you.

      Thank you for the correction. It should be “The 0 position is recommended to be set near the focused position”.

    Will you be adding the Meade LX850/LX600 ACF OTA internal Crayford-style focuser to work with your new EAF?
    It would have to somehow connect to the coarse focuser knob.

    Installing EAF on Celestron Omni XLT 150 Newtonian.
    The EAF bracket would not fit since the bottom side of focuser is not flat. Do you have any suggestions?
    Do you have a separate bracket for the Celestron Omni XLT Newtonian?

    Thank you
