Always perfectly sharp, without manual work<\/strong>
The iOptron iEAF makes manual focusing a thing of the past. At the touch of a button, your telescope automatically and accurately focuses. You will always get razor-sharp images - whether you are photographing or observing.<\/p>\n\n\n\n

\"iOptron<\/figure>\n\n\n\n

Smart and silent focusing<\/strong>
The powerful stepper motor operates smoothly and almost silently. No vibrations, no distractions. You can concentrate fully on what really matters: the image in your eyepiece or on your screen.<\/p>\n\n\n\n

Accurate at any temperature<\/strong>
The built-in temperature sensor compensates for changes in the environment, keeping your focus stable even during long nights under the stars. No more blurry images due to temperature changes.<\/p>\n\n\n\n

User-friendly and compatible<\/strong>
Connect the iEAF via USB and you are ready to go. The focuser works with popular planetarium and imaging software, such as ASCOM, Stellarium<\/em> and Cartes du Ciel<\/em>. Prefer to adjust manually? You can do that at the touch of a button.<\/p>\n\n\n\n

Memory and versatility<\/strong>
The iEAF remembers its last position even after turning off. That means you can always pick up where you left off. It fits most Crayford and rack and pinion focusers and comes with mounting adapters for a perfect fit.<\/p>\n\n\n\n

Your advantage<\/strong>
The iOptron iEAF brings comfort, precision and modern technology to your home. Perfect for astrophotographers and visual observers who don't want to waste time focusing manually.<\/p>\n\n\n\n
