iOptron HEM44 EC Mount Head with Precision Encoders
$6,699.00
iOptron HEM44EC Mount Head! Freedom from cumbersome counterweights and shaft is here!
Introducing the HEM44EC, iOptron’s latest revolutionary hybrid strain wave drive mounts. These lightweight, compact, medium payload titans will deliver an astronomy experience like never before. Imagine a mount head weighing in at 6.2kg with a payload capability 20kg, without needing a cumbersome counterweight or shaft. Applying iOptron’s multi-decade experience creating precision mounts, the HEM44 EC Mount Head 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 HEM44 EC Mount Heade delivers unparalleled weight to payload efficiency. It's black anodized all metal CNC machined body is not only appealing to the eye, 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).
A HEM44 EC Mount Head 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.
HEM44 mounts with low latitude range (0~22 degree) are available via special order.
