iOptron HEM27 Mount GoTo WiFi: 3.7 kg hybrid EQ mount
The iOptron HEM27 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 13.5 kg (29.7 lbs) with a head weight of only 3.7 kg (8.15 lbs).
This basic version comes without a polar scope: alignment can be done via the control system's alignment routines, or you can expand it later with the iPolar for SkyHunter and HEM27.
With head and camera bag under 5 kg, this is the travel mount for serious deep-sky photography.



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
- HEM27 mounting head
- Go2Nova 8409 Hand Controller

Featured accessories
Expand the mount with the iPolar for SkyHunter and HEM27 for electronic polar alignment, and the HEM27 counterweight shaft for heavier setups.
For whom yes and for whom no
