The ZWO AM3 Harmonic Drive Mount is a revolutionary altazimuth mount designed for astrophotographers and visual astronomers who are looking for a lightweight, portable and precise mount for their long exposure astrophotography. The ZWO AM3 Harmonic Drive Mount is exceptionally lightweight, weighing only 3.9kg, making it easy to transport to remote dark-sky locations. Despite its compact design, it handles an 8kg payload without counterweights and up to 13kg with counterweights, allowing it to support a wide range of telescopes.

With Dual Mode Flexibility, effortlessly switch between Equatorial Mode for precise astrophotography tracking and Altazimuth Mode for visual observations, making it ideal for both seasoned astrophotographers and stargazing enthusiasts of all levels. At the core of the AM3 is advanced precision engineering. The strain wave gear reducer and synchronous belt system provide a 300:1 reduction ratio, ensuring smooth, accurate motion with minimal periodic error of ±20", delivering consistently sharp astrophotography results. Engineered specifically for astrophotography, the mount’s custom strain wave gear minimises periodic error while delivering robust torque. Each mount undergoes rigorous testing and includes a personalised periodic error (PE) curve for optimal tracking precision.

The AM3 is designed for intuitive and flexible control. Operate the mount via Wi-Fi, Bluetooth, or the included hand controller, and take advantage of the ASI Mount App, which offers features like Tonight’s Target, GOTO functionality, and Live Preview, all accessible from your smartphone or tablet.

Portability Meets Stability

The AM5 features strain wave gear reducer and synchronous belt, offering impeccable control and an incredible reduction ratio of 300:1.

Equatorial or Altazimuth Mode

Switch seamlessly between Equatorial and Altazimuth Modes using the ASI Mount App or the hand controller. Equatorial Mode is ideal for precise tracking and photography, while Altazimuth Mode enhances visual astronomy.

Adjustable Pitch Angles

Fine-tune your viewing experience with adjustable pitch angles. Gear 1 permits degrees between 0 and 60, while Gear 2 facilitates adjustments between 30 and 90 degrees after loosening the hex-head screw.

Harmonious Integration with ASIAIR

For the ultimate astrophotography experience, ASIAIR seamlessly connects and controls the AM5 mount via wired or wireless connections, delivering unparalleled performance in the world of stargazing.
