The advantages at a glance:
- Harmonic drive technology
- Load capacity of up to 13.5kg with a mount weight of only 3.7kg
- Tried-and-tested iOptron Go2Nova software with hand controller and a database containing 212,000 objects
- No tangled cables
- Dual Vixen & Losmandy mounting saddle
- Automatic stopping if the power supply is interrupted unexpectedly
- Exceptional tracking, even without guiding
The iOptron HEM27 mounts provide the excellent features of a “large” equatorial mount and, due to “Harmonic Drive” technology, can be used without counterweights or a counterweight shaft. Despite its low weight of only 3.7kg, it has a maximum load capacity of up to 13.5kg. This gives HEM mounts an exceptional weight-to-load ratio as well as having amazing features such as permanent periodic error correction (PEC), automatic mount stopping in the case of power outages with no need to repeat set-up after starting up again, precise tracking (even without guiding), internal cable management, a dual prism clamp for Vixen and Losmandy rails, high-quality CNC machined and anodised materials, tried-and-tested iOptron Go2Nova 8409 software, built-in WiFi, and iOptron’s trademark exceptionally quiet drive.
Our expert comment:
The HEM27 is powered by a 2.5 x 5.5mm connector.

Please read the Quick Setup Guide (QSG) BEFORE setting up and operating the mount! Please also read the full online instruction manual for details. A HEM mount has an internal cable management system. To avoid cable damage, a mechanical stopper is implemented on the RA-axis in order to prevent rotation of more than 360 degrees. Due to the powerful torque of the strain wave gear in these mounts, damage to the stopper may occur, if
1.) “Site and Time” are incorrectly set and 2.) The mount is started from an incorrect Zero Position. Please perform these steps when initiating the HEM mount: “MENU => Zero Position => Searching Zero Position” in order to establish Zero Position. Then manually slew the mount past the meridian by 20 degrees.
