ZWO AM5N Harmonic Drive Mount – Ultra-Portable Precision Equatorial Mount for Astrophotography

The ZWO AM5N Harmonic Equatorial Mount is a next-generation harmonic drive telescope mount designed for serious astrophotography and advanced visual observing. Combining strain wave gear technology, lightweight portability, and high-precision tracking, the AM5N delivers professional-level performance without the bulk of traditional equatorial mounts.

If you're searching for a lightweight equatorial mount with no counterweight required, exceptional tracking accuracy, and full ASCOM compatibility, the ZWO AM5N is one of the most advanced portable mounts available today.

Harmonic Drive (Strain Wave Gear) Technology

The AM5N uses a 300:1 reduction ratio strain wave gear system combined with synchronous belts and precision stepper motors to provide smooth, backlash-free tracking.

Periodic Error: < ±10"
Resolution: 0.17 arcseconds
PE Cycle Duration: 288s
Max Slew Speed: 6°/second

This makes the AM5N ideal for long-exposure deep sky astrophotography, high-resolution planetary imaging.

High Payload Capacity – No Counterweight Needed

Despite weighing only 5.5 kg (12.1 lbs), the ZWO AM5N supports:

15 kg (33 lbs) without counterweight
20 kg (44 lbs) with counterweight

This allows you to mount refractors, astrographs, or compact SCT setups without the complexity of heavy counterweight systems. For portable astrophotographers, this is a major advantage.

Dual Mount Modes: Equatorial & Alt-Az

The ZWO AM5N operates in:

Equatorial Mode (EQ) – optimized for astrophotography
Alt-Az Mode – ideal for visual observing and outreach

Latitude adjustment range: 0° – 90°
Azimuth adjustment: ±6°

Compatible with both Losmandy and Vixen dovetail saddles.

Full Connectivity & Smart Integration

The AM5N supports:

ASCOM
LX200 protocol
USB connectivity
Wi-Fi
Bluetooth
ST4 Autoguider Port

Integrated cable management keeps your setup clean and organized.

Built for Extreme Conditions

Operating temperature: -20°C to 40°C

Perfect for winter astrophotography sessions.

⚠ Recommended input voltage: 12V
If voltage drops below 10.8V, the mount will emit an under-voltage warning beep. For optimal performance, use the official ZWO power adapter and properly rated power cables.

Features

*Note: The recommended operating voltage for the ZWO Harmonic Equatorial Mount is 12V. When the actual input voltage is below 10.8V, the mount will emit a beeping alarm to indicate under-voltage condition. To ensure proper functioning of the equipment, we recommend using the official ZWO power adapter and an appropriately sized power cable.

Tout simplement superbe

Tout simplement superbe, cette monture est magnifique tous mes problèmes sont résolus depuis que j’utilise cette monture. Stabilité de communication réseau, guidage hors pair en plus d’être très silencieuse. P.A. Très facile à faire et que dire du suivi ultra efficace et de la robustesse du boîtier. Gestion des câbles très propre de façon bien ordonnée et sans risque d’accident. Je la recommande fortement pour ma part rien de négatif mais dispendieuse.

The AM5N mount is a fabulous device

The AM5N mount is a fabulous device, making stargazing simpler and more enjoyable. There thousands of objects in its database, and one can add any number of new targets (e.g. comets) and click "goto" and it'll take you there effortlessly. Easy to get gong, seamlessly integrated with ASIAIR Plus and its respective app.
For years, I've been doing the "hunter & seeker" approach, manually targeting which remains fun, but the AM5N certainly adds another dimension to stargazing and astrophotography.

AM5N is an excellent mount

I am getting better RMS guiding values than with my heq5 and it is lighter and easier to move and setup. I am keen to travel to other locations to do AP.

Very quiet

This thing is very quiet and smooth. It also helps with cable management. One power cord in. I still have to use power cords for the dew heaters . But that manageable. Shipping was fast. I haven’t been able to use it yet do to the weather hope to get some clear skies soon.

Great product, excellent service from Astronomy Plus.

ZWO AM5N Harmonic Mount

The ZWO AM5N harmonic mount is an amazing piece of technology for astrophotography. No complaints. Fast shipping from Astronomy Plus. Happy with my purchase.

Thank you so much for the kind words! We're thrilled to hear you're loving the ZWO AM5N. Fast shipping is something we take pride in, so it's wonderful to know that came through.

Clear skies and don't hesitate to reach out if you ever need anything!

Fast and

Fast and accurate

Fantastic for AP

Fantastic for AP. My first EQ mount. Works great with the ASIAir. Reasonably fast polar alignment; guiding consistently around/below .5" guiding error.

Thank you for your review! We are thrilled to hear that the ZWO AM5N Harmonic Drive Equatorial Mount is working great for your astrophotography needs. We are glad to know that it is easy to use with the AsiAir and provides fast polar alignment. Happy stargazing!

Light weight and fast

Great! Looking forward to trying it in the field.
Integrates with NINA just fine.

Awesome mount

Awesome mount.It's such a game changer in astrophotography.Expensive but well worth the price. Also Astronomy Plus amazing services as usual!

Very solid mount, well made, easy to use, good tracking

Love the AM5n

So glad I upgraded to the ZWO AM5n. It is so well made and works great! Astronomy Plus is the best store in Canada for Astronomy equipment and service.

ZWO AM5N

The mount comes conveniently packaged and is a fraction of the weight of a SW EQ6, and handles my TV NP101, guidescope and camera flawlessly, using about 1 amp of power. Super travel mount.

Surprenant

Le poids de cette monture avec sa qualité de précision sont surprenants.
Bravo pour le service.

5 stars for Fast shipping and availability

Monture ultra légère

Cette monture supporte très facilement um Celestron 8 avec caméra et accessoires. Très précise et facile à mettre en place et à aligner sur le pôle. Elle est tellement légère qu'il faut la lester avec un poids dans une poche prévue à cet effet. J'utilise la batterie pour ce faire. Jusqu'à présent, contrairement à certains commentaires vu sur internet, un peu de vent ne fait pas vibrer la monture.

Love the new power port on the dec axis. ZWO needs to put more usb ports here as well and up the amperage to at least 5 amps.

Excellent,
