This remarkable 3.73 payload-to-weight ratio is achieved through an 800:1 reduction gear system that delivers backlash-free motion without the need for counterweights. With a built-in 11.1V battery, GPS, and Wi-Fi, the HAZ71 offers a complete, self-contained platform for serious visual astronomy and outreach.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eStrain Wave Gear Drive: An 800:1 Reduction Ratio with Zero Backlash\u003c\/h3\u003e\n      \u003cp\u003eAt the core of the HAZ71 is its advanced strain wave gear (SWG) system on both axes. This technology, born from robotics, uses a flexible, tooth-engaged gear to achieve an enormous 800:1 reduction ratio, providing exceptional torque to handle heavy and off-center loads. For the astronomer, this means instant, backlash-free response when slewing and tracking, eliminating the frustrating gear slop common in traditional worm-drive systems.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eA 3.73 Payload-to-Weight Ratio: Carry 68 lbs on an 18.3 lb Head\u003c\/h3\u003e\n      \u003cp\u003eThe HAZ71's most significant advantage is its incredible power density. It can carry a 68 lb telescope rig, yet the all-metal, CNC-machined head weighs a mere 18.3 lbs. This 3.73 payload-to-weight ratio is class-leading and fundamentally changes how you approach a night of observing. Large SCTs or refractors that would typically demand a heavy, cumbersome equatorial mount can now be deployed on a lightweight, grab-and-go system.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eGo2Nova Controller: ~212,000 Objects with Built-in Wi-Fi \u0026amp; GPS\u003c\/h3\u003e\n      \u003cp\u003eLocating celestial targets is handled by the proven Go2Nova® 8409 hand controller, containing a database of approximately 212,000 objects.

Setup is further simplified by an integrated GPS, which automatically acquires your location, date, and time, ensuring accurate pointing right from the start of your session.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n    \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eField-Ready Power: Built-in 11.1V Battery and Electronic Brake\u003c\/h3\u003e\n      \u003cp\u003eDesigned for portability, the HAZ71 includes a built-in 11.1V, 4.4AH rechargeable Li-ion battery, eliminating the need for external power packs and trailing cables. This internal power source is sufficient for several hours of typical use. A key safety feature is the electronic friction brake, which automatically engages when the power is turned off, preventing your telescope from swinging freely and ensuring your equipment remains secure.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eHAZ71 vs. Traditional GEMs: The 68 lb No-Counterweight Advantage\u003c\/h3\u003e\n      \u003cp\u003eFor a traditional German Equatorial Mount (GEM) to handle a 68 lb payload, it would require an equally heavy counterweight, bringing the total system weight to well over 100 lbs. The HAZ71 needs no counterweights, cutting setup time and physical strain dramatically.
