Introducing the iOptron HEM27, a revolutionary hybrid harmonic drive equatorial GoTo mount with a payload capacity of almost 30 pounds but a mount head weight of just over 8 pounds...and there is no need for a counterweight shaft or counterweight!

All versions of the iOptron HEM27 harmonic mount are light weight, high payload tiny titans that will deliver an astronomy experience like never before.  Utilizing state of the art harmonic drive technology for the RA movement in tandem with backlash-free DEC worm/belt drive design, the iOptron HEM27 delivers 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 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).

This iOptron HEM27 package includes a hand controller and case.  The tripod is optional.  Other HEM27 models include iPolar (H272A) or the EC version with iPolar and a high precision RA encoder (H274A).
