iOptron HAZ71 Alt-Azimuth Strain Wave GoTo Mount
- 68 lbs (31 kg) payload capacity
- 18.3 lbs (8.3 kg) mount head weight
- 3.73 payload-to-weight ratio
- Strain Wave Gear system with 800:1 reduction
- Built-in Wi-Fi, GPS, and 11.1V rechargeable battery
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.
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.
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.
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.
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.
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.
The 18.3 lb HAZ71 head is rated at a 68 lb payload, a payload-to-weight ratio of 3.73, with no counterweight.
The HAZ71 is an altazimuth mount. Altazimuth tracking does not compensate for field rotation, which limits long exposures; an equatorial mount avoids it.
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.
The HAZ71 is rated at 68 lbs (31 kg). The head weighs 18.3 lbs (8.3 kg) with its dual Vixen & Losmandy saddle.
No. The HAZ71 is rated at 68 lbs with no counterweight.
The power-off brake is an electronic friction brake, so the axes are held when the mount is not powered.
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.
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.
