Introducing the new ZWO AM3N Mount
What's been upgraded?
The ZWO AM3N solves a range of astrophotography hassles
Streamlined Setup, Enhanced Mount Efficiency
Ditch the clutter; the AM3N, paired with the ZWO AIR Series camera and ZWO EAF PRO, eliminates the need for complicated adapters and messy cabling.
With just two power cables (connecting the AM Series mount and ASIAIR), you can achieve a clean, efficient setup and dive straight into deep-sky astrophotography — faster and easier than ever.
Strain Wave Gear for Precision Control
ZWO developed the special strain wave gear based on the actual needs for astrophotography. The strain wave gear system comes with very low periodic errors, smooth gearing, and high torque.
The mount’s internal structure is optimized with a strain wave gear reducer and synchronous belt, delivering precise control and an impressive 300:1 reduction ratio.
Each mount is tested and shipped with an individual periodic error (PE) curve report.
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 represents the periodic error.
The periodic error is consistently controlled 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 body design for better portability and cable management.
The dovetail saddle now includes both a Type-C and 12V DC output port, helping eliminate cable clutter and reducing the risk of tangling — no more cable mess.
Additionally, it includes a magnetic hex wrench that attaches securely to the mount body, ensuring convenient access and storage.
Powerful Payload Capacity: 8 –13 kg
It can support up to double its own weight 8 kg without counterweights, and over triple its weight 13 kg when used with counterweights.
This payload capacity easily accommodates a wide range of telescopes, providing a solid and reliable foundation for your observing and imaging needs.
Based on ZWO's internal testing:
- Maximum load without the counterweight: 8 kg (maximum output torque: 16N · m);
- Supported counterweight: ≤ 5 kg. Maximum load capacity with the counterweight: 13 kg
- The counterweight should be secured on a counterweight bar of no more than 25 cm in length
Equatorial Mode / Altazimuth 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 gear tension knob to achieve a scale between 0 and 60.
Gear 2: Loosen M6 hex wrench and then adjust the altitude gear fine adjustment knob to achieve a scale between 30 and 90.
Wi-Fi & Bluetooth Connectivity
The AM3N supports Bluetooth control, allowing you to operate the mount directly from your smartphone — no Hand Controller required. Ideal for travel and field use, just bring your phone and you're ready to observe or image.
Easily Controlled with Mobile Apps
App offers an onscreen joystick, including Tonight’s Target, GOTO, Live Preview and so many great functions can all be achieved with your phones. There is no need to connect to a computer—the mount and Hand Controller connect via Wi-Fi.
The mount is compatible with ASCOM, INDI, ASIAIR, and other platforms.
Seamless ASIAIR Integration
ASIAIR can connect to the AM3N wirelessly or via cable, offering full control at your fingertips. Enjoy the ultimate astrophotography experience with the ZWO Ecosystem, where all your gear works together, flawlessly.
