  • iOptron HAZ31 Strain Wave Alt-Az Mount

    The iOptron HAZ31 Strain Wave Alt-Az Mount carries a 31 lb (14 kg) payload on a mount head that weighs 8.2 lbs (3.7 kg) with its saddle, a payload-to-weight ratio of 3.78. Both axes use strain wave gears with a 480:1 reduction ratio. It has built-in GPS and Wi-Fi and comes with a Go2Nova 8409 hand controller with a database of ~212,000 objects.

    Strain Wave Gears: A 480:1 Reduction Ratio Without Counterweights

    The HAZ31 uses strain wave gears on both axes, with a 480:1 reduction ratio, driven by stepper motors. Tracking is automatic.

    As an altazimuth mount it uses no counterweight.

    The 3.78 Payload-to-Weight Ratio: 31 lbs on an 8.2 lb Head

    The mount head weighs 8.2 lbs (3.7 kg) with its dovetail saddle and carries up to 31 lbs (14 kg), a payload-to-weight ratio of 3.78.

    Go2Nova Controller: 212,000 Objects with Built-in GPS & Wi-Fi

    The HAZ31 has built-in GPS and built-in Wi-Fi. The control system is GOTONOVA/Commander, with Wi-Fi and USB communication via the hand controller.

    For traditional control, the included Go2Nova 8409 hand controller has a database of ~212,000 objects. The maximum slew speed is 8º per second.

    CNC-Machined Construction with a Dual Dovetail Saddle

    The HAZ31's body is all metal and CNC machined, with an anodized black finish and a level bubble. The firmware is upgradeable.

    • Dual Saddle: The saddle takes both Vixen and Losmandy dovetail bars.
    • Electronic Brake: The power-off brake is an electronic friction brake.
    • Operating Range: -20ºC to 40ºC.

  • What is the main advantage of the iOptron HAZ31's strain wave design?

    The 8.2 lb mount head is rated at a 31 lb payload, a payload-to-weight ratio of 3.78, with no counterweight.

    Does the iOptron HAZ31 need counterweights?

    No. The HAZ31 takes no counterweight; the payload rating is 31 lbs (14 kg).

    Can I do long-exposure astrophotography with the alt-azimuth iOptron HAZ31?

    The HAZ31 is an altazimuth mount. Altazimuth tracking does not compensate for field rotation, which limits long exposures; an equatorial mount avoids it.

    What do I need to power the iOptron HAZ31 mount in the field?

    The mount runs on DC 12V, 5A through a 5.5/2.1mm DC plug, and draws 0.6A tracking and 1A during GoTo. The included 100V ~ 240V AC adapter is for indoor use only.

    How do the built-in GPS and Wi-Fi on the iOptron HAZ31 work?

    The mount has built-in GPS and built-in Wi-Fi, with Wi-Fi and USB communication via the hand controller and the GOTONOVA/Commander control system.

    What does the electronic friction brake on the iOptron HAZ31 do?

    The power-off brake is an electronic friction brake, so the axes are held when the mount is not powered.

    What kind of tripod is needed for the iOptron HAZ31?

    The tripod is listed as an optional accessory. iOptron does not give the HAZ31 base size or tripod interface in its HAZ31 specifications.

    What is included in the box with the iOptron HAZ31 mount?

    The standard iOptron HAZ31 package includes the mount head itself, a Go2Nova 8409 hand controller for GoTo operation, and a 100V-240V AC power adapter (indoor use only). The tripod is optional.
