The conventional equatorial mount requires heavy counterweights. Maintaining balance in the RA and DEC directions can be very difficult and inconvenient for transport and storage, causing considerable pain for amateur astrophotographers when out imaging.
Some of the pull-shaft drive mounts have a relatively simple function, but lack sufficient load-bearing capacity and are also not very stable in use.
To solve the above-mentioned problems, ZWO developed the ASI Mount series. No counterweight is required. With a net weight of 3.9 kg, the AM3 has a large load capacity of 8 kg to 13 kg. While portability is very important, stability in use is also essential. Rather than blindly pursuing a lightweight mount, ZWO focuses on stability throughout the entire application. The internal structure of the mount is optimized with a pull-shaft gear and synchronous belt, ensuring more precise control and an astonishing reduction ratio of 300:1. It is also multifunctional and can be used as both an equatorial mount and an altazimuth mount. You can control the mount either via Wi-Fi and Bluetooth or with a hand controller.
Portable and Stable

Custom-Made Tension Shaft Gear
ZWO developed the special tension shaft gear based on the actual requirements of astrophotography. It features very low periodic error and high torque. Each mount is tested before leaving the factory and equipped with an exclusive PE curve to guarantee quality.
3.9 kg net weight
Rather than blindly pursuing the lightweight of the mount body, ZWO focuses on stability throughout the entire application.
8 kg–13 kg payload
The load capacity of the AM3 without counterweight is 8 kg and 13 kg with counterweight.
According to technical calculations, we can calculate the maximum load capacity of the AM3 mount:
8 kg without counterweight
13 kg with counterweight.
Supported counterweight: ≤5 kg
The counterweight should be attached to a counterweight rod no longer than 25 cm.
Equatorial Mode / Altazimuth Mode
Can be switched via the ASI Mount app or the hand controller.
Equatorial Mode: Suitable for tracking and photographing objects.
Altazimuth Mode: Suitable for visual astronomy.
0°-90° All-round elevation angle.
Gear 1: Allows adjustment of the elevation angle to a range of 0 to 60 degrees.
Gear 2: You can loosen the hex screw and then adjust the elevation handle to a range of 30 to 90 degrees.
Wireless Control
Tonight's Target, GOTO, live preview, and so many other great features can be accessed with your phones.
Rocker-style hand controller
Pleasant feel and easy to use. Integrated into a Wi-Fi network, allowing wireless control. You can easily upgrade the hand controller's firmware and install it on the website.
Seamless integration with ASIAIR
ASIAIR can control the AM5 via a wired or wireless connection. The ASI package offers its customers the best astrophotography experience.
*Note: The recommended operating voltage for the ZWO Harmonic Equatorial Mount is 12 V. If the actual input voltage is below 10.8 V, the mount will emit a beeping alarm to indicate a low-voltage condition. To ensure proper operation, we recommend using the official ZWO power adapter and an appropriately sized power cable.
What's in the box?
Accessible tools
