The HEM27 is one of iOptron's game-changing hybrid mounts driven by cutting-edge strain wave technology. This featherweight yet mighty mount promise an astronomical experience like no other. Imagine a mount head that tips the scales at a mere 3.7kg, yet can effortlessly support a whopping 13.5kg of equipment, without needing counterweights.

At the core of these mounts lies state-of-the-art strain wave drive technology for the right ascension movement, working in tandem with a backlash-free declination worm/belt drive design. This delivers an unparalleled weight-to-payload efficiency ratio. The black anodized, all-metal CNC-machined body is not only a visual stunner but also a rugged platform engineered to perform at the highest level for years to come. Unique features, such as an electronic friction brake and power-down memory, ensure that the mount can safely pause and resume a GoTo slew or continue tracking even after an abrupt power loss, eliminating the need to realign and start from scratch.

Controlling the HEM27 mount is a breeze, whether you prefer using a computer with ASCOM/Commander for Windows or a third-party INDI driver for MacOS software, a smartphone/tablet with iOptron Commander Lite or apps like SkySafari, or a Raspberry Pi device via an INDI driver.
