iOptron's HEM27 Hybrid Strain Wave Drive Mount is a revolutionary hybrid that is lightweight, with a high payload to deliver an astronomy experience like never before. Weighing in at 8.2 pounds, it supports up to 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 appealing to the eye, with a rugged platform that will perform at the highest level for many years to come. Unique features include an electronic friction brake and power down memory so you can safely stop the mount and resume a GoTo slew or continue tracking even after an abrupt power loss (no need to realign and start from the beginning). It can be controlled via computer using ASCOM/Commander for Windows PC or a third-party INDI driver for macOS software, via a smart phone or tablet using iOptron Commander Lite or an app like SkySafari, or via a Raspberry Pi device using INDI driver.
