A Compact Telescope Mount Built for Big Results
The ZWO AM5N is a next-generation strain wave mount designed for astrophotographers and visual observers who want power, portability, and precision in one sleek package.
With upgraded electronics, improved tracking performance, and a higher payload capacity, the AM5N builds on the success of the original AM5, making it even easier to travel light and set up fast.
Whether you're imaging from your backyard or a remote dark sky site, the AM5N delivers accurate, wireless-controlled tracking in both equatorial and alt-az modes.
Why Choose the ZWO AM5N
High Payload Capacity
The AM5N supports up to 33 lbs (15kg) without counterweights, that’s 15% more than the discontinued AM5’s 28.6 lbs (13kg). This means you can bring heavier cameras or telescopes on the go without adding bulky counterweights.
Take It Anywhere
The ZWO AM5N is built for portability. Weighing just 12 lbs (5.5kg), it's easy to carry, pack, and transport. Its compact, all-in-one design means fewer components to haul and assemble, making it perfect for on-the-go astrophotography or quick visual sessions.
Precise Tracking
The AM5N features a high-precision drive system that keeps tracking accurate and smooth, reducing periodic error to just ±10 arcseconds. That means you’ll get cleaner, sharper long-exposure images with less star trailing.
Wireless Connectivity
Take full control of your ZWO AM5N mount using its built-in Bluetooth and WiFi. Aside from the power cable, everything else is wireless, making setup and operation easy and mostly cable-free!
To operate wirelessly, you will need to connect the included rocker-style hand controller to the mount. It houses the Wi-Fi module that lets your device communicate with the mount.
Next, you will need to use the ZWO ASI Mount app to set up and control everything using a phone or tablet. The app is available on the Google Play Store or the Apple App Store.
If you ever need it, the hand controller gives you full manual control. You can quickly point the mount to any deep-sky object you want to view or photograph.
ASIAIR Ready
For a fully integrated experience, the AM5N also works seamlessly with ZWO’s smart telescope controller, the ZWO ASIAIR. Using the ASIAIR app, you can control the mount alongside your ZWO camera, filter wheel, guide camera, EAF, and more, all from a single interface. Check out ZWO’s range of accessories. It also works with ZWO's all-in-one 'Air' astronomy cameras.
Strain Wave Technology: Ditch the Counterweights
The ZWO AM5N uses strain wave gear technology, eliminating the need for counterweights when carrying imaging setups up to 33 lbs (15kg). That’s a game-changer for anyone who wants a lighter, faster setup without sacrificing performance.
Without bulky counterweights, the AM5N is easy to carry outside for quick backyard sessions or to pack in your luggage for travel to a dark sky site. The AM5N combines precise tracking performance with a compact, travel-friendly design, making it easy to take your imaging setup wherever the night takes you.
For larger telescope rigs, you can still add counterweights and a counterweight shaft (sold separately) to increase the payload capacity to 44 lbs (20kg).
Dual Equatorial & Alt-Azimuth Modes
The AM5N’s ability to switch between equatorial (EQ) and alt-azimuth modes lets you tailor your setup to exactly what you need.
For a quick and easy setup, alt-azimuth mode simplifies aiming with minimal alignment required. It's a great choice for casual visual observing or imaging the Moon and planets.
For astrophotography and longer exposures, switch to EQ mode. In EQ mode, the mount tracks the sky’s rotation, keeping your telescope aligned with stars and deep-sky objects as the Earth turns. This prevents star trailing and keeps your images sharp.
Thanks to its full 0–90° latitude range, the AM5N works anywhere on Earth, whether you’re at home, traveling, or exploring new dark sky locations.
This flexibility makes it a great choice for beginners learning the ropes and for experienced astronomers who need a versatile, travel-friendly mount.
Built for Quick Setup
The ZWO AM5N features a redesigned base with no azimuth locking knobs or external clutches, giving it a cleaner, more modern look. This simplified design makes setup faster and polar alignment easier. Instead of clutches, the AM5N uses an internal brake on the RA axis to keep your telescope securely in place.
Safety Tip: Always make sure the mount is on a stable surface before starting your session.
Power-Off Protection Keeps Your Telescope Safe
The ZWO AM5N features built-in power-off protection for added safety and peace of mind. If your power supply gets interrupted during a session, the mount automatically engages its internal brake. This holds the mount firmly in place, preventing your telescope from slipping, drifting, or tipping over unexpectedly.
This feature is especially useful if you're imaging with a heavier setup or operating remotely, as it protects both your equipment and your alignment.
Multiple Ports For All Your Devices
The AM5N mount head comes with 4 handy ports to make your setup smooth and versatile:
- USB 2.0 port: Connect accessories like the ZWO ASIAIR for easy wireless control of your mount and imaging gear.
- ST-4 port: Hook up a guide camera here for precise autoguiding, which helps keep your long-exposure photos sharp.
- Hand controller port: This is where you plug in the included rocker-style hand controller for manual pointing and wireless communication.
- 12V DC power port (5.5x2.1mm): Powers the mount directly from your power source, keeping everything running steady during your session.
These ports make the AM5N compatible with popular astrophotography tools and accessories, giving you flexibility whether you’re shooting from the backyard or traveling to dark skies.
Optional ZWO TC40 Carbon Fiber Tripod
The ZWO TC40 Carbon Fiber Tripod (sold separately) is the ideal match for the AM5N mount. It weighs 5 lbs (2.3kg), and it can support up to 110 lbs (50kg). The TC40 is strong, so your gear stays safe and stable, whether you're imaging at home or traveling to a dark sky site. Check out the ZWO TC40

It also works with ZWO's all-in-one 'Air' astronomy cameras.
Strain Wave Technology: Ditch the Counterweights
The ZWO AM5N uses strain wave gear technology, eliminating the need for counterweights when carrying imaging setups up to 33 lbs (15kg). That’s a game-changer for anyone who wants a lighter, faster setup without sacrificing performance.
Without bulky counterweights, the AM5N is easy to carry outside for quick backyard sessions or to pack in your luggage for travel to a dark sky site. The AM5N combines precise tracking performance with a compact, travel-friendly design, making it easy to take your imaging setup wherever the night takes you.
For larger telescope rigs, you can still add counterweights and a counterweight shaft (sold separately) to increase the payload capacity to 44 lbs (20kg).
Dual Equatorial & Alt-Azimuth Modes
The AM5N’s ability to switch between equatorial (EQ) and alt-azimuth modes lets you tailor your setup to exactly what you need.
For a quick and easy setup, alt-azimuth mode simplifies aiming with minimal alignment required. It's a great choice for casual visual observing or imaging the Moon and planets.
For astrophotography and longer exposures, switch to EQ mode. In EQ mode, the mount tracks the sky’s rotation, keeping your telescope aligned with stars and deep-sky objects as the Earth turns. This prevents star trailing and keeps your images sharp.
Thanks to its full 0–90° latitude range, the AM5N works anywhere on Earth, whether you’re at home, traveling, or exploring new dark sky locations.
This flexibility makes it a great choice for beginners learning the ropes and for experienced astronomers who need a versatile, travel-friendly mount.
Built for Quick Setup
The ZWO AM5N features a redesigned base with no azimuth locking knobs or external clutches, giving it a cleaner, more modern look. This simplified design makes setup faster and polar alignment easier. Instead of clutches, the AM5N uses an internal brake on the RA axis to keep your telescope securely in place.
Safety Tip: Always make sure the mount is on a stable surface before starting your session.
Power-Off Protection Keeps Your Telescope Safe
The ZWO AM5N features built-in power-off protection for added safety and peace of mind. If your power supply gets interrupted during a session, the mount automatically engages its internal brake. This holds the mount firmly in place, preventing your telescope from slipping, drifting, or tipping over unexpectedly.
This feature is especially useful if you're imaging with a heavier setup or operating remotely, as it protects both your equipment and your alignment.
Multiple Ports For All Your Devices
The AM5N mount head comes with 4 handy ports to make your setup smooth and versatile:
- USB 2.0 port: Connect accessories like the ZWO ASIAIR for easy wireless control of your mount and imaging gear.
- ST-4 port: Hook up a guide camera here for precise autoguiding, which helps keep your long-exposure photos sharp.
- Hand controller port: This is where you plug in the included rocker-style hand controller for manual pointing and wireless communication.
- 12V DC power port (5.5x2.1mm): Powers the mount directly from your power source, keeping everything running steady during your session.
These ports make the AM5N compatible with popular astrophotography tools and accessories, giving you flexibility whether you’re shooting from the backyard or traveling to dark skies.
Optional ZWO TC40 Carbon Fiber Tripod
The ZWO TC40 Carbon Fiber Tripod (sold separately) is the ideal match for the AM5N mount. It weighs 5 lbs (2.3kg), and it can support up to 110 lbs (50kg). The TC40 is strong, so your gear stays safe and stable, whether you're imaging at home or traveling to a dark sky site. Check out the ZWO TC40

Frequently Asked Questions
What Type of Mount Is the ZWO AM5N?
The ZWO AM5N is a dual-mode telescope mount. It works in both Equatorial (EQ) mode and Alt-Azimuth (Alt-Az) mode. EQ mode is ideal for astrophotography because it tracks the sky as the Earth turns. Alt-Az mode is easier to set up and perfect for visual observing. You can switch modes using the ZWO app or hand controller—no tools needed.
Is the AM5N Good for Visual Observing?
Absolutely. In Alt-Az mode, you don’t need to worry about polar alignment. It’s quick to set up and intuitive to use, making it ideal for relaxed observing or showing friends and family the night sky. And the tool-free process to switch from Alt-Az to EQ modes takes less than 5 minutes!
Can I Use the AM5N for Solar Imaging?
Yes! The precise tracking and smooth movement make it suitable for a variety of imaging styles, including solar observations (with proper solar filters).
Does the AM5N Require Counterweights?
Not for most setups. The AM5N can hold up to 28.6 lbs (13kg) for imaging and 44 lbs (20kg) for visual observing without counterweights, thanks to its advanced strain wave gear system. If you're using a heavier telescope or want extra balance, you can add a standard counterweight bar and weight (sold separately). These payloads are also somewhat dependent upon the length of the telescope system, so for longer scopes like a slower refractor, you may have to dial back the maximum payloads.
What Is the Weight of the AM5N Mount Head?
The AM5N mount head weighs just 8.6 lbs (3.9kg). It’s lightweight and compact, which makes it easy to carry, store, or take to dark sky sites. Great for travel!
Does the AM5N Include a Tripod?
That depends on the bundle. Some versions of the AM5 come with the ZWO TC40 Carbon Fiber Tripod, while others include just the mount head. If you’re using your own tripod, make sure it has a 3/8"-16 center bolt to fit the mount. Shop the bundle pack.
How Do I Power the AM5N?
The mount runs on a 12V DC power supply with a 5.5 x 2.1 millimeter plug and needs at least 5 amps. This is standard for many astronomy accessories. The power cable isn’t included, so you’ll need to get one separately.

All of these GoTo functions are controlled using the ZWO app or an ASIAIR for a wireless experience.
What Kind of Polar Alignment Does It Use?
The AM5N doesn’t have a built-in polar scope. Instead, it uses software-based polar alignment through the ASIAIR app or guiding programs. This method is easier and more accurate than lining things up by eye, and it is especially helpful if you’re a beginner.
Can I Autoguide With the AM5N?
Yes. The AM5N supports autoguiding, which means it can make tiny corrections to keep your telescope accurately tracking during long exposures. It supports both the ST-4 port and control through ASIAIR or a computer.
Is the AM5N Waterproof or Weather-Resistant?
The AM5N is not fully weatherproof. It’s designed for use under clear skies, so it’s important to protect it from rain and moisture.
