Precise focus is critical for astrophotography, and the iOptron iEAF (#8453) delivers the consistency and fine control your imaging setup demands. This compact, lightweight electronic focuser mounts directly to your telescope’s existing focuser and provides hands-free, computer-controlled focus adjustments through USB. Whether you're shooting deep sky targets or planetary details, the iEAF helps you achieve pinpoint sharpness—automatically.
Designed with automated imaging in mind, the iEAF is compatible with popular software platforms like NINA, Sequence Generator Pro, and Ekos/KStars, using ASCOM or INDI drivers for integration. While it’s not optimized for visual use, the unit does include onboard directional buttons for quick, local adjustments during setup or testing.
Key Features:
-
Built for Astrophotography: Designed specifically for imaging applications—automated focusing between filters, compensating for temperature shifts, or hands-off focus routines during long sessions.
-
USB-Controlled Autofocus: Easily connects to your imaging PC or hub via USB 2.0. Supports ASCOM (Windows) and INDI (Linux/Mac/Raspberry Pi) platforms.
-
Onboard Adjustment Buttons: Includes physical up/down focus buttons on the body for local, manual movement when not connected to software—useful for setup and quick tweaks.

Observing Tip:
Even with temperature compensation or filter offsets dialed in, autofocus routines occasionally need a helping hand. The onboard buttons let you fine-tune focus locally when setting up in the field—no hand controller or laptop required. Once focus is locked in, let the software take over and keep it there all night.
