Introducing the HEM27 and the HEM27EC, iOptron’s revolutionary hybrid harmonic drive mounts. These light weight, high payload tiny titans will deliver an astronomy experience like never before. Imagine a mount head weighing in at 8.15lbs with a payload capability 29.74lbs, without needing a cumbersome counterweight or shaft. Applying iOptron’s multi decade experience creating precision mounts, the HEM27 brings this vision to reality.
Utilizing state of the art harmonic drive technology for the RA movement in tandem with backlash-free DEC worm/belt drive design, the HEM27s deliver 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 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).
The HEM27EC features a high precision RA axis encoder that delivers incredible tracking accuracy, enough that many will choose to image “sans” guiding.
