iOptron HEM27 Overview
iOptron's HEM27 Hybrid Strain Wave Drive Mount is a revolutionary hybrid strain wave drive mount. This lightweight, high payload tiny titan will deliver an astronomy experience like never before. Imagine a mount head weighing in at 8.2 pounds with a payload capability of 29.7 pounds, without needing a cumbersome counterweight or shaft.
Utilizing state-of-the-art strain wave drive technology for the RA movement in tandem with backlash-free DEC worm/belt drive design, the HEM27 delivers unparalleled weight to payload efficiency. Its 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 brake 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 from the beginning). A HEM27 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.
