iOptron HEM44 Mount iPolar: hybrid EQ power with electronic polar scope
The iOptron HEM44 is a hybrid equatorial mount: strain wave drive on the right ascension axis, backlash-free worm and belt drive on the declination axis. Without a counterweight, it carries 20 kg (44 lbs) in a head that remains light enough for mobile use.
This version has a built-in iPolar electronic polar scope: you align with the celestial pole on your laptop screen, quickly and accurately.
Twenty kilos of payload capacity without a counterweight means you can carry a serious astrograph with a complete imaging train, while the setup remains light and quick to assemble.
Align on screen
The iPolar camera shows the celestial pole and the direction of the polar axis; the software calculates with date, time, and refraction. Within minutes, the mount is precisely aligned, even without a clear view of the Pole Star.
Hybrid drive without counterweight
The combination of strain wave on RA and worm/belt on declination provides the load capacity of a harmonic drive with the refined tracking behavior of a traditional drive. A counterweight is unnecessary in most setups.
The electronic friction brake safely stops the mount during a power failure, and the power-down memory preserves position and alignment.
Complete control
The Go2Nova 8409 hand controller contains over 200,000 objects; Wi-Fi is routed through the hand controller, and computer control is possible via ASCOM, INDI, or iOptron Commander. Autoguiding via the ST-4 port and PEC correction are built-in.
The internal cable management and the dual Vixen/Losmandy-D saddle keep the photo setup tidy; the built-in zero-position finder automatically finds the starting position.
Included
- HEM44 mount with built-in iPolar

Featured accessories
Combine the mount with the LiteRoc tripod for this class and the 15 cm MiniPier for clearance around the zenith.
For whom yes and for whom no
- ✓ Astrophotographers with tubes up to 20 kg who want a light and fast setup
- ✗ Anyone who wants to photograph without guiding: choose the HEM44 EC
