iOptron is changing the game again. The HEM44 Strain Wave mount looks to the future for performance today.
Say hello to the HEM44, iOptron’s revolutionary hybrid strain wave drive mount. The light weight, medium payload mount will deliver an astronomy experience like never before. Imagine a mount head weighing in at 13.65lbs with a payload capability of 44lbs, without needing a cumbersome counterweight or shaft. Applying iOptron’s multi decade experience creating precision mounts, the HEM44 brings this vision to reality.
Utilizing state of the art strain wave drive technology for the RA movement in tandem with backlash-free DEC worm/belt drive design, the HEM44s 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).
This is a mount head only. You will need a tripod of some sort. The 8061 Carbon Fiber tripod from iOptron is a great choice. Very stable and very lightweight.
