iOptron’s HEM15 mount offers excellent features of a “large” equatorial mount and, due to “Harmonic Drive” technology, can be used without counterweights/a counterweight shaft. Despite its low weight of only 2.5kg, it has a maximum load capacity of up to 8kg (with the use of optional counterweights up to 12kg). This gives the HEM mount 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, an extensive prism clamp for Vixen and 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:
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.
