iOptron HAE43B-EC AZ/EQ - Powerful precision in a compact design
The iOptron HAE43B-EC AZ/EQ combines power, precision and portability in one modern mount. Thanks to the innovative Harmonic Drive Technology move smoothly across the sky without the hassle of heavy counterweights. You get professional tracking performance in a light, smart and reliable system - ideal for astrophotography as well as visual observation.

Powerful, without counterweight
With a carrying capacity of 20 kg, expandable to 25 kg with optional weights, the HAE43B-EC effortlessly supports large telescope tubes and cameras. Because the mount works with Dual Strain Wave Gear on both axes, you no longer need a long counterweight bar. Less weight means faster set-up and easier transport - perfect for mobile observers.
Smart technology on board
The built-in iMate computer turns your mount into a self-contained observing platform. With WiFi, open-source software (KStars, INDI, Ekos) and 32 GB internal memory you control everything directly from your smartphone, tablet or laptop. No extra laptop needed - just control your session through your favorite app.
Incredible precision with integrated encoders
The high-resolution encoder continuously tracks the position of the mount and corrects even the smallest deviation. That means razor-sharp tracking without periodic error correction or autoguider. Even at long exposure times, your stars remain sharp and round.
Reliable and safe
A electronic friction brake intervenes immediately in case of power failure. As soon as you turn the mount back on, it automatically calibrates itself and knows exactly where it was. Your session continues as normal, without the need for re-alignment.
Robust, precise and elegant
The CNC-machined aluminum housing with black anodizing feels solid and is built to last for years. Internal cabling and connectors on the saddle (USB and 12V) keep your setup neat and secure - no loose wires while tracking or shooting.
Everything you need
The HAE43B-EC comes with DC12V power supply, tote bag, and full connectivity. Whether you work with Windows, macOS, Linux or Android - this mount effortlessly adapts to your workflow.
The iOptron HAE43B-EC AZ/EQ is the perfect choice for those seeking maximum performance in a compact, smart and professional mount.
