1. HEM44 Overview
Introducing the HEM44 and the HEM44
EC, iOptron’s revolutionary hybrid strain wave drive mounts.
These light weight, medium payload titans will deliver an astronomy experience like never before. Imagine a
mount head weighing in at 13.65lbs with a payload capability 44lbs, without needing a cumbersome
counterweight or shaft. Applying iOptron’s multi decade experience creating precision mounts, the HEM44
brings this vision to reality.
Utilizing state of the art strain wave drive technology for the RA movement in tandem with backlash-
free DEC worm/belt drive design, the HEM44s deliver unparalleled weight to payload efficiency. Its black
anodized all metal CNC machined body is not only appealing to the ey
e, it’s a rugged platform that will
perform at the highest level for many years to come. 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).
The HEM44EC features a high precision RA axis encoder that delivers incredible tracking accuracy,
enough that many will choose to image “sans” guiding.
The iOptron HEM44 mount uses the Go2Nova
®
8409 hand controller to navigate the night sky. This
incredible technology helps observers find celestial objects with the aid of the mount's 212,000+ object
database!
A HEM44 mount can be controlled by a computer, either 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 Pro; or a Raspberry Pi device via INDI driver.
