Why AM3N?
AM3N vs AM3
Tired of Complicated Mount Wiring?
Messy cables can easily get tangled and even damage your gear.
Frustrated with Heavy Gear During Field Trips?
Transporting bulky setups can drain your energy before you even start imaging.
Still Struggling with Star Trails and Poor Tracking?
Losing pinpoint stars due to inaccurate tracking ruins the perfect shot.
Engineered for simplicity: two cables deliver a clean, efficient setup that gets you imaging faster than ever.
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.
ZWO measures each mount and equips it with an exclusive PE curve before it leaves our factory.
The X-axis represents the drive angle, and the Y-axis shows the periodic error, which is consistently maintained within ±15 arcseconds.
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.
Equatorial Mode / Alt-azimuth Mode
Can be switched via SkyAtlas App or Hand Controller.
Status Light Indicator
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 features built-in Wi-Fi and Bluetooth, enabling direct smartphone control — no Hand Controller required. 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.
