What is the main advantage of the iOptron HAZ71's strain wave gear system?
The primary advantage of the Strain Wave Gear is its ability to deliver extremely high torque and precision with zero backlash in a very compact and lightweight package. This allows the 18.3 lb HAZ71 head to carry a 68 lb payload without needing any counterweights, making it exceptionally portable for its capacity.
Can I use the iOptron HAZ71 for long-exposure astrophotography?
As an alt-azimuth mount, the HAZ71 is subject to field rotation, which makes it unsuitable for unguided, long-exposure deep-sky imaging. It is designed primarily for visual astronomy, public outreach, and Electronically-Assisted Astronomy (EAA) where many short exposures are stacked to create an image.
How long does the HAZ71's built-in 4.4AH battery last?
The 11.1V, 4.4AH Li-ion battery's duration depends on usage. With continuous tracking, it will last for many hours. Frequent slewing at the maximum 6°/sec speed will consume more power. For a typical visual observing session with moderate GoTo use, you can expect a full evening of operation on a single charge.
What kind of telescope can I mount on the HAZ71? Will it handle a Celestron C11 for visual use?
Yes, absolutely. With its 68 lb payload capacity, the HAZ71 is an excellent match for large Schmidt-Cassegrains like a Celestron C11 or even a C14 for visual observing. It can also easily handle large refractors or Newtonian reflectors, provided they fit within the weight limit. The dual Vixen/Losmandy saddle accommodates most telescope mounting plates.
How does the HAZ71's GPS and Wi-Fi improve my session when viewing Jupiter and Saturn?
The built-in GPS automatically sets your precise location and time, which is critical for the GoTo system to accurately find objects like Jupiter and Saturn. The built-in Wi-Fi allows you to control the mount with a planetarium app on your phone or tablet, making it easy to look up information about the planets and slew to them with a simple tap on the screen.
Does the iOptron HAZ71 mount require counterweights?
No. Thanks to the high-torque strain wave gear drive, the HAZ71 does not require any counterweights, even when loaded to its full 68 lb capacity. This is a major factor in its portability and rapid setup time compared to traditional equatorial mounts.
