iOptron HAZ130 Dual SWG Altazimuth Mount

Dual Strain Wave Gear: 132 lb Capacity with Zero Backlash

At the core of the HAZ130 are two independent strain wave gear systems for the altitude and azimuth axes. This technology, born from robotics, provides exceptional torque from a compact, lightweight mechanism and completely eliminates the backlash inherent in traditional worm-gear systems. The result is immediate directional response and precise tracking for a total instrument payload of up to 132 lbs, all without the cumbersome setup of counterweights and shafts.

Go2Nova 8411 Controller with Built-in GPS

Setup and object location are streamlined by the Go2Nova 8411 hand controller and its integrated Commander control system. The built-in GPS automatically acquires the precise time, date, and location, simplifying the initial alignment process. The controller's OLED display is easy to read in all lighting conditions, providing intuitive access to the mount's tracking and GoTo functions for any target in the sky.

70 lb CNC Machined Body with Electronic Braking

The HAZ130 is built for stability and field reliability from a CNC-machined, all-metal structure with an anodized black finish. An electronic friction brake automatically engages when power is cut, protecting your payload from accidental movement. Engineered to function in temperatures from -20ºC to 40ºC, this 70 lb mount provides a robust and dependable platform for your most demanding observing sessions.

6°/sec Slewing and Full 180° Altitude Range

This mount combines heavy-lifting capability with agility. The stepper motor drive slews at up to 6 degrees per second, moving rapidly between celestial targets. The alt-azimuth design allows for a full 0° to 180° range of motion in altitude, enabling you to track objects directly through the zenith without the meridian flips required by equatorial mounts. This makes the HAZ130 ideal for uninterrupted viewing of objects passing overhead.

HAZ130 vs. Worm-Gear Mounts: A New Class of Heavy-Duty Tracking

While traditional worm-and-ring gear systems are proven designs, the HAZ130's strain wave gear technology offers distinct operational advantages for heavy alt-azimuth applications.

• Backlash: Worm gear systems inherently have backlash, which can cause a slight delay or "bump" when changing direction. The HAZ130 has zero backlash, providing instant and precise motor response.
• Torque and Balance: Strain wave gears produce incredibly high torque relative to their size, eliminating the need for counterweights to balance a 132 lb payload. This dramatically reduces the total system weight you have to transport and set up.
• Simplicity: Without the need for balancing, clutch adjustments, or periodic error correction common to worm systems, the SWG design is mechanically simpler and requires less user adjustment in the field.
