iOptron HAZ 31 Alt-Az Strain Wave Mount

iOptron have introduced two exciting new Alt-Az strain wave mounts, the HAZ31 and HAZ46, which are welcome additions to the iOptron strain wave gear mount family!

This lightweight, compact, medium payload HAZ31 mount will deliver an astronomy experience like never before. With a mount head weighing 8.2 lbs, the HAZ31 has a payload capability of 31 lbs, without needing a cumbersome counterweight or shaft. The HAZ will support a large variety of instruments. That flexibility is necessary for outreach programs and satellite tracking. The multi-position saddle (can be placed on top or to the side) uniquely sets up the HAZ31 to accommodate binoculars. Just turn the mount on, and it will calibrate itself and GoTo the first target utilising our time-tested "Lever and Go" technology.

The HAZ31 delivers unparalleled weight to payload efficiency by utilising state-of-the-art strain wave gear technology for both RA and DEC movement. Its black anodised all-metal CNC machined body is a durable, rugged platform that will perform at the highest level for many years. Unique features such as an electronic friction break and power-down memory allow the mount safely stop and resume a GoTo slew or continue tracking even after an abrupt power loss (No need to realign and start from the beginning).

A computer can control a HAZ31 mount via ASCOM/Commander for a Windows PC or a third-party INDI driver for MacOS software; a SmartPhone/Tablet via iOptron Commander Lite or an App like SkySafari; or a Raspberry Pi device via INDI driver.
