About this product
Model: iop_hem15_ipolar
Part Number: H152A
iOptron HEM15 with iPolar
The HEM15 is a new addition to iOptron's range of Hybrid Harmonic Drive Equatorial GoTo Mounts that deliver excellent performance in an ultra-portable package.
The mount head weighs only 5.5 lbs yet can carry a max payload of 18 lbs without needing a counterweight.
Utilising a state-of-the-art strain wave drive technology for the RA movement in tandem with a backlash-free DEC worm/belt drive design, the HEM15 delivers unparalleled weight to payload efficiency.
The black anodised all-metal CNC machined body provides a rugged platform that will perform at the highest level for many years.
Unique features such as an electronic friction break and power-down memory enable the mount safely stop and resume a GoTo slew or continue tracking even after an abrupt power loss (no need to realign and restart).
The HEM15 mount can be controlled by a computer via ASCOM/Commander for a Windows PC or a third-party INDI driver for MacOS), a SmartPhone/Tablet via iOptron Commander Lite or an App like SkySafari, or a Raspberry Pi device via INDI driver.

So far very happy. It's lightweight and robust , and intuitive to use if you have experience with an astrophotography workflow. Manages my 6" F4 reflector plus cameras with no issues.
