The ZWO AM3N is the evolution of the AM3 Harmonic Drive Mount from ZWO. It can operate in altazimuth or equatorial modes.

Like its predecessor, the AM3N is light and capable of carrying a telescope of up to 8kg (and 13kg if you use a counterweight on the mount). Because it’s small and light, it’s a perfect grab and go mount for portable rigs. It is especially useful for chasing solar eclipses where tearing down and setting up quickly might make all the difference!

The latest version, the AM3N, also has internal cabling that provides a USB-C port and 12V DC on the saddle of the mount. Because your telescope rotates with the saddle, you can tie all your cables down securely and avoid the risk of snagging dangling cables.

Strain Wave Gears for Precision Control

Astrophotography demands both stability and accuracy, and the adoption of a custom-engineered strain wave gear system addresses these needs directly. The gear train is designed to minimize periodic error, provide exceptionally smooth motion, and deliver high torque capacity—factors critical for long-exposure imaging.

Within the mount, a strain wave gear reducer works in concert with a synchronous belt drive, yielding precise control and a notable 300:1 reduction ratio. Each unit undergoes individual testing, and a periodic error (PE) curve report is supplied with every mount, offering users verified performance data for confidence in the field.

Integrated Type-C and DC Power Ports

The upgraded AM3N weighs just 4.1 kg (9.04 lbs), with a newly optimized design for improved portability and cable management. The dovetail saddle now integrates Type-C and 12V DC ports to minimize clutter, while a magnetic hex key attaches directly to the mount for convenient storage.

Powerful Payload Capacity: 8 –13 kg

The mount supports up to 8 kg (17.6 lbs) without counterweights—double its own weight—and up to 13 kg (28.7 lbs) with counterweights, more than triple its weight.

This payload capacity easily accommodates a wide range of telescopes, providing a stable and reliable foundation for your viewing and imaging needs.

Based on internal testing:

1. Maximum load without the counterweight: 8 kg (17.64 lbs) (maximum output torque: 16N · m);
2. Supported counterweight: ≤ 5 kg (11.02 lbs). Maximum load capacity with the counterweight: 13 kg (28.66 lbs).
3. The counterweight should be secured on a counterweight bar of no more than 25 cm (9.84 in) in length.

All-round 0°-90° Altitude Scale

The AM3N features a versatile altitude adjustment design ranging from 0° to 90°, allowing for unrestricted use across both low-and high-latitude regions.

Gear 1: Rotate the altitude tension knob for adjustment between 0 and 60.
Gear 2: Loosen the M6 hex screw, and allows adjustment from 30 and 90.

Evolved Portable Control Wi-Fi & Bluetooth Connectivity

The AM3N supports Bluetooth control, enabling direct smartphone control — no Hand Controller required. Wi-Fi functionality is provided through the hand controller, which houses the WiFi transmitter. Ideal for travel and field use, just bring your phone and you’re ready to observe or image.

Wireless Control via Mobile Apps

Operate the mount directly from your phone with an intuitive app featuring an on-screen joystick, Tonight’s Target, GOTO, Live Preview, and more.

The mount is compatible with ASCOM, INDI, ASIAIR, and other platforms.
