The iOptron HAE29C EC delivers high-end harmonic mount performance in a compact, counterweight-free format. With strain wave gear drives on both axes, a RA-axis encoder for real-time tracking correction, and built-in Wi-Fi via its internal control board, the HAE29C EC is the ultimate mobile imaging platform for astrophotographers who want travel-ready performance without compromise.
Despite weighing just 8.8 pounds, the HAE29C EC supports up to 29 pounds of imaging gear—and does it with encoder-enhanced precision and smart, software-driven control.
Harmonic Drive Mechanics + Encoder Accuracy
The HAE29C EC uses strain wave (harmonic) gear drives in RA and DEC for smooth, backlash-free tracking and high torque output. The EC model adds a high-resolution RA encoder that enables real-time periodic error correction, improving tracking performance for long-exposure astrophotography and high-resolution imaging.
Whether you’re guiding lightly, imaging unguided at short focal lengths, or just want maximum consistency from your mount, the RA encoder is a major advantage.
29 lb Payload, No Counterweights Needed
With a payload rating of 29 pounds, the HAE29C EC is ideal for 4"–5" refractors, compact astrographs, and fully accessorized DSLR/CMOS setups. Thanks to its center-balanced design, most payloads do not require counterweights, which keeps your setup lighter and faster to deploy.
Optional counterweight shafts and weights are available for users running front-heavy or long-tube scopes.
Software-Based Control – Built-in Wi-Fi, USB-C, and More
The HAE29C EC includes an internal control board with built-in Wi-Fi, so it can be operated without a hand controller. Control options include:
-
ASCOM + iOptron Commander for Windows
-
INDI driver support for MacOS and Linux
-
iOptron Commander Lite or SkySafari via smartphone/tablet
-
Raspberry Pi devices via INDI (for full automation with Ekos or Stellarmate)
For users who prefer tactile control, the Go2Nova 8411 hand controller is available separately and fully compatible.
Integrated Cable Management
To make your setup cleaner and easier to manage, the HAE29C EC features USB and 12V ports mounted on the saddle—allowing you to power your camera, accessories, and control cables directly through the mount. Fewer dangling wires means better balance, fewer snags, and quicker setup and teardown times.
Built Tough and Designed to Travel
The mount’s CNC-machined aluminum construction provides excellent mechanical rigidity with minimal weight. Electronic friction brakes on both axes protect your gear during sudden power loss or disconnection.
Every HAE29C EC mount includes a form-fit hard case for protection and portability.
