iOptron iEAF Electronic Automatic Focuser

iOptron iEAF Electronic Automatic Focuser: electronic focus motor for your existing focuser

The iEAF motorizes the focuser already on your telescope. The stepper motor couples to the focus shaft via the included mounting plate and then focuses electronically: manually using the buttons or automatically via the computer.

Via ASCOM, the iEAF runs along with autofocus routines in your capture software. The built-in temperature sensor enables temperature compensation, so the focus stays sharp while the optical tube cools down at night.

Quiet and vibration-free

The motor operates virtually silently and without touching the tube: no vibrations in the image during focusing, which is especially important for planetary imaging and high magnification.

Assembly

Mounting plate, mounting hardware, and USB cables are included. Check whether your focuser has a free end of the focus shaft that the coupler fits onto.
