iOptron HAE69B iMate EC Dual Equatorial And Alt-Azimuth Strain Wave Mount Head High Precision Encoder

iOptron HAE69B iMate EC Dual Equatorial and Alt-Azimuth Strain Wave Mount Head with High Precision Encoder (#HE694B)

The high-capacity mount that basically runs itself—and doesn't blink under pressure.

The iOptron HAE69B iMate EC (#HE694B) isn’t just another strain wave mount—it’s a complete, ultra-portable observatory platform in a compact, counterweight-free form. Designed to carry heavy imaging payloads with precision and minimal complexity, the HAE69B iMate EC includes dual strain wave gear drives, a high-resolution RA encoder, and iOptron’s powerful iMate onboard control computer, delivering a self-contained, software-driven mount head built for automation and remote control.

This version, the EC model, includes a precision RA axis encoder for tighter tracking performance. It’s an ideal solution for imagers working at long focal lengths, or those who want to reduce guiding intervention and simplify their data collection workflow.

Strain Wave Drive Muscle in a Compact Chassis

The HAE69B is built around strain wave gear drives (also known as harmonic drives) on both axes. These high-torque, zero-backlash systems replace the bulky worm gears of traditional mounts with compact, efficient, and whisper-quiet gearing that offers exceptionally smooth tracking and slewing. Each axis is geared at an 800:1 reduction ratio, ensuring precise control even with heavy loads.

Despite weighing only 19.8 pounds, the HAE69B can support a payload of 69 pounds without counterweights, and up to 79 pounds with an optional counterweight system. That’s enough for fully-loaded 10" imaging Newtonians, large refractors, heavy astrographs, or SCTs with every accessory you can bolt on.

EC Model: RA Encoder for Guiding Efficiency

The EC designation means this mount includes a high-resolution magnetic encoder on the RA axis, giving it extremely accurate tracking feedback. This translates to smoother motion with fewer guiding corrections and, in some cases, the ability to image unguided at shorter focal lengths or with wide-field instruments.

The EC version is especially useful for users seeking a semi-autonomous mount experience, such as remote operators or imagers who want to reduce software overhead or guide aggressiveness.

iMate: Your Observatory in a Box

What truly sets this version apart is the built-in iMate control system. iMate is a Linux-based onboard mini computer housed inside the mount head, running KStars, Ekos, and INDI drivers out of the box. This means you can run your entire imaging workflow—including mount control, slewing, polar alignment, focusing, plate solving, and capture—without an external laptop.

Access is done remotely, via Wi-Fi or Ethernet, using remote desktop software. You can operate the mount head from a tablet, phone, or laptop—whether you're in the next room or logged in from halfway across the country.

iMate offers:

• Full compatibility with INDI/Ekos/KStars

• Integrated USB 3.0 and USB 2.0 ports

• Ethernet port for direct network connection

• HDMI output for diagnostics or maintenance (no direct peripheral input)

• Wi-Fi hotspot or LAN client modes

Dual Mode Tracking: Equatorial or Alt-Azimuth

Switch between equatorial and alt-azimuth mode depending on your needs. EQ mode is ideal for long-exposure deep-sky astrophotography, while alt-az mode is great for visual observing, planetary work, or EAA sessions where polar alignment may be inconvenient. In alt-az mode, you’ll benefit from no meridian flips and a faster setup time.

This flexibility makes the HAE69B well-suited to backyard setups, observatory installations, and mobile imaging rigs.

Technical Specifications

Observing Tip:

The iMate system is tailor-made for remote imaging. Before heading into the field, preconfigure your Wi-Fi or Ethernet settings and install any imaging profiles or drivers you’ll need. Having everything tested ahead of time makes your first night with the mount a smooth, cable-free experience—even under pressure.
