iOptron HAE43B-EC AZ/EQ Mount Dual SWG iMate: encoder precision plus onboard computer
The iOptron HAE43B-EC is an AZ/EQ mount with strain wave drive (harmonic drive) on both axes. Without a counterweight, it carries 19.5 kg (43 lbs). Use it in alt-azimuth mode for quick visual observing or in equatorial mode for long-exposure astrophotography.
This version combines the high-resolution RA encoder with the built-in iMate mini PC: real-time error correction and a fully autonomous photo session, without a laptop next to the tripod.
This makes it the most autonomous HAE43 in the lineup.

Without guidance, without a laptop
The encoder corrects the periodic error of the strain wave drive in real time; the iMate, using KStars and Ekos, controls the complete session. Two sources of hassle disappear at once.
You can monitor and adjust via Wi-Fi from your phone, tablet, or computer.
iMate: complete onboard minicomputer
The built-in iMate is a 64-bit ARM computer with 32GB of storage and a micro-SD slot, pre-loaded with KStars, Ekos, and INDI drivers. You connect the camera, focuser, and filter wheel directly to the mount, and the entire photo session runs autonomously on board.
You can monitor and adjust settings via WiFi from Windows, macOS, Linux, iOS, or Android. Switched 12V outputs on the cap power your peripherals without loose cables.
Strain wave: power without counterbalance
The strain wave gears deliver a high torque without backlash, making a counterweight unnecessary in most setups. That saves kilograms of heavy lifting and minutes of setup time.
The electronic friction brake on both axes safely stops the mount in case of a power failure, and the power-down memory saves the alignment, so you can continue without re-aligning.
Double saddle, ready for any tube
The dual saddle accepts Vixen and Losmandy-D rails. For heavier or unbalanced setups, add the optional counterweight bar with counterweight.
The head comes with a transport case or bag and without a tripod; it fits on matching iOptron tripods and mounts.
Included
- HAE43B-EC mounting head with RA encoder and built-in iMate
- Transport case
- Power supply and USB cable
Featured accessories
Add the 15 cm MiniPier for the HAE43 for clearance around the zenith, and the LiteRoc tripod for this class as a stable base.
For whom yes and for whom no
- ✓ Astrophotographers who want to shoot autonomously and without guiding up to 19.5 kg
- Who does not need automation: the HAE43C-EC is then more affordable
