About this product
Model: zwo_am3
Part Number: ZWO-AM3
ZWO AM3 Harmonic Drive Mount
Traditional equatorial mounts require counterweights, and maintaining balance in RA and DEC directions can be difficult. Their size/shape can also make them inconvenient for transit and storage.
Some strain wave geared mounts are relatively simple in function, insufficient in load capacity, and not very stable in use.
To solve the above issues, ZWO developed their ASI Mount series. With a body weight of only 3.9kg, the AM3 has a large load capacity from 8kg (without counterweight) to 13kg (with counterweight).
Portability is important, but so too, is stability. Instead of pursuing only the lightest mount body weight, ZWO has paid careful attention to stability and ease of use. The body's internal structure is optimised for the strain wave gear reducer and synchronous belt, bringing more accurate control and an amazing reduction ratio of 300:1.
It can be used as an equatorial or altazimuth mount and controlled via Wi-Fi, Bluetooth, or a hand controller.
Portable and stable
The body's internal structure is optimised for the strain wave gear reducer and synchronous belt, bringing more accurate control and an amazing reduction ratio of 300:1.
Customised Strain Wave Gear
ZWO developed the special strain wave gear based on the actual needs for astrophotography, so it has a very low periodic error and high torque. Each mount is tested at the factory and includes a PE curve chart to maintain quality and performance.
3.9kg Net Weight
ZWO has achieved this low body while maintaining stability and ease of use.
8kg-13kg payload
The load capacity of AM3 without the counterweight is 8kg and 13kg with the counterweight.
* The counterweight should be secured on a counterweight bar of no more than 20cm in length.
Equatorial Mode / Altazimuth Mode
The mode can be switched via ASI Mount App or hand controller.
Equatorial Mode: Suitable for tracking and photographing objects
Altazimuth Mode: Suitable for visual astronomy
All-round 0°-90° Pitch Angle
Gear 1: Allow you to adjust the pitch angle grip to achieve a degree between 0 and 60.
Gear 2: You can loosen the hex-head screw and then adjust the pitch angle between 30 and 90.
Wireless Control
Tonight’s Target, GOTO, Live Preview and other functions can be set using your smartphone.
Rocker-style Hand Controller
Comfortable touch and easy to use. Integrated with Wi-Fi network allowing for wireless control. You can easily upgrade the firmware of the hand controller and mount it on the webpage.
Seamless Linkage with ASIAIR
ASIAIR can control AM5 via a wired or wireless connection. The ASI package gives customers the best astrophotography experience.
What’s in the box
Optional accessories include:
① Pier Extension
With the pier extension, telescopes with a long focal length are less likely to hit the tripod legs.
② Carbon Fiber Tripod

Carbon fibre material: High strength and high impact resistance.
Adjustable height: 470-800mm. Dual-section legs provide a stable and rigid platform for telescopes and cameras.
Spreader plate: Increase the stability of the tripod.
Weight bag: Provides additional stability by filling it with suitable weights such as stones or your telescope battery pack.
Fixed spread angle: Easy to use.

Out of this world performance 29 April 2024 | Jim
Have used this a couple of times with my new ZWO FF65 APO imagining set up. With the ASIAIR plus it is simplicity itself to polar align, and then absolutely spot on with guiding. No trailing with 300 second subs and I anticipate that 600 seconds would also be practical. Also the fact that this is achieved without needing counter balancing is really impressive. The carry case is also well constructed and makes the mount easy to transport to my favourite dark sky location.
Should have bought this earlier. 25 September 2023 | Geir
I suffer from G.A.S - Gear Acquisition Syndrome - after taking up this hobby of astrophotography.
It started with a MAK - 102 and AZ-Gti, which for me was not the right thing.
Then the Adventurer 2i Pro, then Adventurer GTI and now finally what I've been wanting to get, but found a bit expensive - the ZWO AM3.
I wished I should have bought it in the first place. It is just in another league.
It also took some time until I found FLO as the place to buy more "stash".
I am very happy with the service from FLO.

I wanted a smaller mount for my Redcat and 2600MM and also something quicker and easier to set up without the need of a counterweight. The mount worked flawlessly with the ASI Air and guides very well. It is super quiet when it slews.
