Discover the HEM27 and HEM27EC, the revolutionary mounts with hybrid strain wave (harmonic) drive from iOptron. These lightweight little titans with high payload capacity will provide an unprecedented astronomy experience. Imagine a mount head weighing 3.7 kg with a payload capacity of 13.5 kg, without the need for a counterweight or bulky shaft. Drawing on iOptron's multi-decade experience in creating precision mounts, the HEM27 realizes this vision.

Utilizing advanced strain wave (harmonic) drive technology for right ascension (RA) movement in tandem with a backlash-free design for declination (DEC) screw/band movement, the HEM27 offers unmatched weight-to-payload efficiency. Its black anodized CNC machined metal body is not only attractive but also a robust platform that will perform at the highest level for many years. Unique features include an electronic friction brake to safely stop movement during a planned or unforeseen power interruption.

A HEM27 mount can be controlled by a computer, either via ASCOM/Commander for a Windows PC or a third-party INDI driver for MacOS software; a smartphone/tablet via iOptron Commander Lite or an app like SkySafari; or a Raspberry Pi device via an INDI driver.

The HEM27EC is equipped with a high-precision RA axis encoder that offers incredible tracking accuracy, sufficient for many to choose to image "without" guiding.
