The iOptron HAE69C harmonic equatorial mount delivers observatory-class performance in a portable package built for today’s serious imagers. With a strain wave gear drive system, center-balanced architecture, and up to 69 pounds of payload capacity—all without the need for counterweights—the HAE69C redefines what a high-capacity mount can be.
Whether you're imaging from a dark-sky site or automating a backyard observatory, the HAE69C offers the precision, strength, and simplicity to support your most ambitious rigs—while staying light enough to travel.
Strain Wave Gear Performance in Both Axes
At the heart of the HAE69C is a pair of strain wave (harmonic) gear drives, one on each axis. This advanced gearing system is renowned for zero backlash, high torque, and exceptionally smooth motion. The result is accurate slewing and tracking—ideal for long exposure astrophotography, high-resolution sensors, and narrowband work.
Combined with the mount’s center-balanced design, the harmonic drive system allows the HAE69C to carry large imaging payloads without the weight, complexity, and bulk of traditional counterweight systems.
True 69 lb Payload, Ultra-Portable Mount Head
The HAE69C mount head weighs just 19.8 lbs (9.0 kg)—yet it’s capable of supporting up to 69 lbs of gear when properly balanced. That’s more than enough for large refractors, fully-loaded SCTs, and complete imaging setups with filter wheels, focusers, and cameras.
For particularly long or front-heavy payloads, an optional counterweight shaft and weights can be added. But for many setups, the HAE69C keeps things simple and stable—without anything extra to haul around.
CNC Machined for Rigidity and Reliability
The HAE69C features a black anodized, all-metal CNC-machined chassis, combining rugged durability with a clean, professional look. This is a mount built to thrive under field conditions while maintaining the precision required for high-end astrophotography.
The saddle supports both Vixen and Losmandy D-style plates, and the mount head attaches to a tripod or pier via a standard base.

Final Thoughts
The iOptron HAE69C is a harmonic drive equatorial mount that hits the sweet spot between capacity, portability, and performance. With strain wave gears in both axes, a center-balanced design, and a payload rating that rivals much larger mounts, it’s a flexible and future-ready platform for demanding imagers.
Whether you’re building your dream mobile rig or looking for a powerful solution for remote observatory control, the HAE69C is built to keep up—and deliver.
Observing Tip:
For best tracking and guiding performance, keep your payload’s center of gravity as close to the mount’s rotational axis as possible. The more balanced the load, the less work the motors do—and the better your results will be across longer imaging sessions.
