iOptron HAZ71 AZ SWG Mount Head

The iOptron HAZ71 is a harmonic drive mount that brings serious payload capacity to an alt-az platform—without the counterweights, without the backlash, and without the setup hassle. Built around a rugged, all-metal CNC-machined body and powered by strain wave gear technology in both axes, the HAZ71 supports up to 68 pounds (31 kg) of equipment while weighing just 18.3 pounds fully loaded with its dual-style dovetail saddle.

Whether you’re mounting a large binocular, a wide-field imaging refractor, or a hefty SCT, the HAZ71 delivers unmatched strength, simplicity, and smoothness in a compact alt-az form factor. If you're looking for a powerful mount that can handle serious gear—but still travels light—the HAZ71 sets a new standard.

Harmonic Drive Power, Alt-Az Freedom

At the heart of the HAZ71 is a strain wave gear drive system in both the azimuth and altitude axes. This advanced harmonic technology eliminates the backlash common to traditional worm gears while delivering extremely high torque and precision. That means smooth slews, rock-solid tracking, and no need for counterweights, even with heavy instruments.

This design also enables a sleek, lightweight chassis that’s tough enough for observatory-class gear, yet portable enough to take to remote sites.

68 lb Payload with No Counterweights

Despite its compact size, the HAZ71 punches well above its weight class. It supports up to 68 pounds of telescope and accessories—enough for 6" to 8" refractors, large binoculars, or fully loaded imaging rigs. With a 3.73:1 payload-to-weight ratio, the HAZ71 delivers professional-grade performance without the setup drag of heavy counterweights or polar alignment.

Its dual-position saddle can be configured for top- or side-mounted gear, letting you easily switch between a telescope or binoculars depending on your setup needs.

Setup Made Simple: Level and Go

iOptron's proven "Level and Go" routine means you don’t need to polar align or manually calibrate. Just level the mount, turn it on, and let it auto-calibrate and slew to the first target. The built-in GPS locks your location automatically, and the mount searches for its zero position using internal sensors—no guesswork, and no need for external apps or polar scopes.

The system is designed to be fast, intuitive, and repeatable, whether you're observing planets from your backyard or chasing satellites at an outreach event.

Electronic Friction Brakes for Added Safety

The HAZ71 includes electronic friction brakes on both axes, providing an important safety feature during power loss or emergency stops. If the power is interrupted—planned or not—the brakes automatically engage to hold your gear in place. This protects your telescope, camera, and mount from unexpected swings or drops.

CNC Machined and Built to Last

The HAZ71’s anodized black, all-metal CNC-machined construction is as rugged as it is beautiful. With precision machining throughout, this is a mount built for longevity—capable of withstanding years of use in field conditions. The built-in level bubble helps with fast alignment, and the mount base uses a standard 3/8-16 threaded hole for tripod or pier mounting.

Built-In Battery, Wi-Fi, and Versatile Control

The HAZ71 includes a built-in rechargeable Li-ion battery (11.1V, 4.4Ah) for power-anywhere convenience. You’ll get hours of operation without needing external power—ideal for remote sites and grab-and-go setups.

Mount control options are impressively flexible:

• Go2Nova 8409 V2 hand controller with 212,000-object database

• Built-in Wi-Fi (via hand controller) for control via iOptron Commander Lite, SkySafari, or other mobile apps

• USB connection for firmware updates and PC/Mac control via ASCOM or INDI

• Compatible with iOptron iMate and other INDI-based platforms like Raspberry Pi

It’s ready for planetary, deep-sky, solar, or even satellite tracking with third-party software.

Final Thoughts

The iOptron HAZ71 is a standout in the harmonic drive category—combining precision engineering, high payload capacity, and truly portable convenience in one easy-to-use mount. Whether you’re observing with large binoculars, imaging with a heavy refractor, or simply want a no-fuss platform that sets up fast and tracks all night, the HAZ71 is ready to deliver.

Observing Tip:
To get the best pointing accuracy, make sure your mount is perfectly level and give the GPS a few moments to sync fully before starting your session. The built-in zero position locator ensures consistent slews—just power up and go.
