  • iOptron HAZ71 Alt-Azimuth Strain Wave GoTo Mount

    The iOptron HAZ71 Alt-Azimuth Strain Wave GoTo Mount uses strain wave gears with an 800:1 reduction ratio to carry a 68 lb (31 kg) payload on a head that weighs 18.3 lbs (8.3 kg) with its saddle, a 3.73 payload-to-weight ratio. It has a built-in 11.1V, 4.4AH Li-ion battery, built-in GPS and Wi-Fi, a GoToNova system with a ~212,000 object database, and slews at up to 6°/sec in azimuth.

    Strain Wave Gear Drive: An 800:1 Reduction Ratio

    The HAZ71 uses strain wave gears (SWG) on both axes with an 800:1 reduction ratio, driven by stepper motors. As an altazimuth mount it uses no counterweight.

    A 3.73 Payload-to-Weight Ratio: Carry 68 lbs on an 18.3 lb Head

    The HAZ71 is rated for 68 lbs (31 kg), and the all-metal, CNC-machined head weighs 18.3 lbs (8.3 kg) with its dovetail saddle: a 3.73 payload-to-weight ratio.

    GoToNova Control: ~212,000 Objects and 6°/sec Slewing

    Control is through the Go2Nova® 8409 hand controller, with a database of approximately 212,000 objects. The mount slews at up to 6° per second in azimuth and 3.6° per second in altitude.

    Tracking is automatic, and the control system is GOTONOVA/Commander.

    Integrated Systems: A 4.4AH Battery, GPS, and Wi-Fi

    The HAZ71 has a built-in 11.1V, 4.4AH rechargeable Li-ion battery, with a charger rated 100-240V AC input, 12.6V DC 2A output. The mount draws 0.7A during tracking and 1.7A during GoTo; no runtime is stated, and the battery has a 90-day warranty.

    • Built-in GPS
    • Built-in Wi-Fi: via the hand controller.
    • USB Port: A USB port on the hand controller provides a wired connection, and the firmware is upgradeable.

    Electronic Brake and Dual Vixen/Losmandy Saddle

    The power-off brake is an electronic friction brake.

    The dual saddle takes Vixen and Losmandy dovetail bars. The mounting base is a 3/8"-16 threaded hole, and a tripod or MiniPier is optional. There is a level bubble, and the operating range is -20ºC to 40ºC.

  • What is the main advantage of the iOptron HAZ71's strain wave gear system?

    The 18.3 lb HAZ71 head is rated at a 68 lb payload, a payload-to-weight ratio of 3.73, with no counterweight.

    Can I use the iOptron HAZ71 for long-exposure astrophotography?

    The HAZ71 is an altazimuth mount. Altazimuth tracking does not compensate for field rotation, which limits long exposures; an equatorial mount avoids it.

    How long does the HAZ71's built-in 4.4AH battery last on a single charge?

    iOptron does not state a specific runtime in hours. The mount's power consumption is 0.7A while tracking and 1.7A during GoTo slews. Since frequent slewing uses more power than continuous tracking, the total operating time from the 11.1V, 4.4AH battery will vary based on use. The battery has a 90-day warranty.

    What payload is the iOptron HAZ71 rated for?

    The HAZ71 is rated at 68 lbs (31 kg). The head weighs 18.3 lbs (8.3 kg) with its dual Vixen & Losmandy saddle.

    Does the iOptron HAZ71 mount require counterweights?

    No. The HAZ71 is rated at 68 lbs with no counterweight.

    What is the purpose of the electronic friction brake on the HAZ71?

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

    What tripods are compatible with the iOptron HAZ71's mounting base?

    The mounting base is a 3/8"-16 threaded hole, and a tripod or MiniPier is optional. Make sure your tripod is rated for the mount plus your payload.

    Is the Go2Nova 8409 hand controller required to operate the iOptron HAZ71?

    Wi-Fi and USB communication run via the hand controller, so the Go2Nova 8409 is the link for both. No box list is available for the HAZ71, so it is not confirmed whether the hand controller is included.
