Part Number: H442a
iOptron HEM44 Hybrid Strain Wave Drive Equatorial Mount with iPolar.
iOptron’s latest revolutionary hybrid strain wave drive mount.
These lightweight, compact, medium payload titans deliver an astronomy experience like never before. Imagine a mount head weighing in at 13.65 lbs with a payload capability of 44 lbs, without needing a cumbersome counterweight or shaft. Applying iOptron’s multi-decade experience creating precision mounts, the HEM44 makes this vision possible.
Utilising state-of-the-art strain wave drive technology for the RA movement with a backlash-free DEC worm/belt drive design, the HEM44s deliver unparalleled weight to payload efficiency.
The black anodised, metal CNC machined body is a 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 to safely stop and resume a GoTo slew or continue tracking even after an abrupt power loss (no need to realign and start again from the beginning).
A HEM44 mount can be controlled by a computer, either via ASCOM/Commander for a Windows PC or a third-party INDI driver for a MacOS software; a SmartPhone/Tablet via iOptron Commander Lite or an App like SkySafari; or a Raspberry Pi device via INDI driver.
The HEM44EC features a high-precision RA axis encoder that delivers incredible tracking accuracy, enough that many will choose to image “sans” guiding.
The HEM44 mount with a low latitude range (0~22 degrees) is available via special order.
This version includes an iOptron iPolar electronic polarscope that enables quick, easy and accurate polar alignments, even when you cannot see the pole star!
