Product Details

  • Behold the newest focusing innovation from ZWO -- the 5V EAF! It is the upgraded version of the original ZWO EAF that enables accurate and dynamic focus control that is ideal for planetary and deep-sky imaging.

    The advanced version of the 5V EAF comes with the EAF body, flexible coupling, motor bracket, USB2.0 cable, hand controller, and temperature sensor.

    Compared to the original version, the biggest change for the 5V EAF was the removal of the 12V power supply port. This means that you can now directly connect it to your camera, laptop, or ASIAIR PRO via the USB 2.0 port and cable for both data transmission AND power supply! You cable management will be significantly easier and the supply pressure will be drastically reduced as well.

    The intricate pattern that is shown on the side of the 5V EAF is not only aesthetically pleasing, but it is inspired by the changes of Airy disk during focusing and the focusing curve, making it clear at a glance how this focuser works.

    Compatible Software

    • ASCOM
    • INDI
    • ASAIR and ASIStudio
    • USB HID device and drive-free

    NOTE: Check out this list from ZWO to see if your focuser is compatible with the ZWO 5V EAF. If your focuser is not on this list, check the mechanical drawing and this guide.

Great products, great service.

A slight delay, due to supply chain demand, but incredible selection and service.
