Applying iOptron's proven experience in creating precision mounts, the HEM27 series brings this vision to reality.
Using state of the art harmonic drive technology for the RA movement in tandem with a light weight conventional DEC worm gear drive, the HEM27s delivers amazing weight to payload efficiency. The black anodised all metal CNC machined body is an appealing and 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 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).
For those who want the absolute best tracking, the HEM27EC model features a high precision RA axis encoder that delivers incredible tracking accuracy.
