ZWO AM5N mount

ZWO AM5N Mount: Revolutionizing Portable Astrophotography

The ZWO AM5N mount is the latest innovation from ZWO, building on the highly successful AM5 model. Designed for astrophotographers and professionals who demand both portability and high precision, the AM5N combines cutting-edge Harmonic Drive technology with thoughtful design improvements that make it more versatile, accurate, and user-friendly than its predecessor. If you’re looking for a compact yet powerful mount that delivers exceptional tracking performance for deep-sky and planetary imaging, the AM5N is the perfect solution.

Harnessing Harmonic Drive Technology for Superior Performance

At the core of the ZWO AM5N is its Harmonic Drive (also known as a strain wave drive) system, which is renowned for its ability to offer superior tracking precision and load-bearing capabilities while maintaining a lightweight design. Unlike traditional worm gear mechanisms, which are prone to backlash and mechanical wear, the Harmonic Drive in the AM5N provides a much smoother, more accurate slewing experience.

The Harmonic Drive technology, which ZWO has employed across both the AM5 and AM5N models, is a game-changer for astrophotographers who require highly accurate, long-exposure tracking. It allows the AM5N to handle larger optical setups without any compromise in performance. With a maximum payload capacity of 20 kg without counterweights, it’s ideal for those using more extensive and heavier gear, providing a level of performance typically only seen in much larger mounts.

Significant Upgrades: AM5N vs. AM5

The ZWO AM5 quickly became a favorite for portable astrophotography setups due to its precision, ease of use, and integration with ZWO’s other products like ASIAIR. However, ZWO has gone a step further with the AM5N, introducing several upgrades and refinements that make it even more appealing.

• Increased Load Capacity: One of the most significant improvements in the AM5N is the increased load capacity. While the AM5 could handle 13 kg without counterweights, the AM5N steps it up to an impressive 20 kg. This expanded capacity means astrophotographers can now mount heavier optical systems, including larger telescopes and cameras, without the need for additional counterweights. For those who travel frequently for imaging sessions or prefer to minimize the equipment they carry, this feature is a massive advantage.
• Enhanced Electronics for Improved Tracking: ZWO has also refined the internal electronics of the AM5N. These enhancements result in more accurate and reliable tracking, minimizing drift during long exposures—a critical aspect for astrophotographers focused on deep-sky imaging. The optimized electronics allow for smoother slewing motions, ensuring that every movement of the mount is precise. This is particularly beneficial when shooting objects that require pinpoint accuracy, such as planets or galaxies.
• Upgraded Polar Alignment: The AM5N features an upgraded polar alignment system that significantly reduces setup time. With firmware improvements that offer faster and more accurate polar alignment, the AM5N allows users to get imaging quicker, making it easier to capture high-quality images without unnecessary delays. The new polar alignment functionality is designed to be more intuitive, allowing even those new to astrophotography to achieve accurate alignment with minimal effort.
• Quieter Operation: The AM5N also addresses one of the few areas where the original AM5 could improve: noise levels. While the AM5 operated at around 60 dB during slewing, the AM5N is even quieter at 50 dB, making it perfect for suburban or remote settings where ambient noise should be kept to a minimum. The quieter operation is particularly useful for late-night imaging sessions when you want to avoid disturbing neighbors or wildlife.
• Broader Tripod Compatibility: Responding to customer feedback, ZWO ensured that the AM5N is compatible with popular iOptron tripods in addition to ZWO’s own lightweight tripod. This broader compatibility gives users more flexibility in how they build their imaging setup. Whether you’re using a heavy-duty tripod for stability in windy conditions or a more lightweight option for easy portability, the AM5N has you covered.

Keeping it Portable Without Compromising Power

One of the standout features of the AM5N is how it balances portability with high-end performance. Weighing just 5 kg, the mount remains lightweight and easy to transport, yet its 20 kg load capacity makes it one of the most powerful portable mounts available. The lightweight design is ideal for astrophotographers who need a highly mobile setup, whether they’re traveling to remote dark-sky locations or simply setting up in their backyard.

Despite its small footprint, the AM5N offers the kind of tracking accuracy and slewing precision you’d typically find in much heavier mounts. The Harmonic Drive technology is the key to maintaining this balance, allowing the AM5N to perform exceptionally well even under the weight of large telescopes and cameras. Additionally, the mount’s ability to handle such heavy loads without requiring counterweights simplifies the overall setup process, saving time and effort.

No Counterweights, No Problem

One of the major advantages of the ZWO AM5N is its ability to handle significant payloads without needing counterweights. This feature not only makes it easier to transport and set up the mount, but it also reduces the need for additional accessories, which can be cumbersome to carry. While the mount does offer the option to use counterweights for ultra-heavy setups, most users will find that the AM5N performs exceptionally well without them, thanks to its innovative Harmonic Drive mechanism.

For those who are using the mount with larger optical systems or cameras, the ability to forego counterweights offers increased flexibility and convenience. Whether you’re imaging wide-field landscapes or zooming in on distant galaxies, the AM5N is capable of delivering smooth, accurate tracking without the extra bulk of counterweights.

Seamless Integration with ASIAIR and Smart Control

ZWO products are known for their integration with the ASIAIR smart control system, and the AM5N is no exception. The mount is fully compatible with the ASIAIR ecosystem, allowing users to control all aspects of their imaging setup wirelessly from a smartphone or tablet. With the ASIAIR app, you can remotely control the mount, polar align, guide, and even plate solve with ease, making the AM5N a true hands-free solution.

The optimized firmware ensures that the AM5N works flawlessly with ASIAIR, offering seamless control over slewing, tracking, and alignment. This integration simplifies the entire imaging process, allowing you to focus on capturing stunning astrophotographs rather than worrying about complicated manual adjustments.

Superior Tracking and Guiding Accuracy

Astrophotographers need precision, especially when dealing with long exposures. The ZWO AM5N excels in both tracking and guiding, thanks to its refined electronics and Harmonic Drive technology. The mount delivers a Periodic Error (PE) of less than ±10 arcseconds without guiding, a significant improvement over the AM5’s already impressive ±20 arcseconds. This reduction in periodic error ensures smoother tracking and less need for guiding corrections, making it easier to capture high-quality images over extended exposure times.

The guiding performance of the AM5N has also been enhanced, with guiding errors typically around 0.3 arcseconds RMS, down from 0.5 arcseconds RMS on the AM5. This improvement is especially beneficial for those who rely on auto-guiding systems for deep-sky imaging, ensuring more consistent results across longer imaging sessions.

Easy Setup and Operation

ZWO has always aimed to make astrophotography accessible, and the AM5N follows in this tradition with an intuitive, user-friendly design. The upgraded polar alignment system allows for faster setup times, while the ASIAIR integration streamlines the entire imaging process. Whether you’re a seasoned astrophotographer or just getting started, the AM5N is designed to make your experience as seamless and enjoyable as possible.

The quick setup means more time imaging and less time configuring. With intuitive controls and a range of smart features, the AM5N is perfect for anyone looking to elevate their astrophotography game.

Future-Proof and Built to Last

Investing in high-quality astrophotography equipment is a long-term decision, and the ZWO AM5N is built to provide years of reliable service. Its durable construction ensures that it can withstand the demands of fieldwork, while the precision of the Harmonic Drive technology guarantees high performance even after years of use. ZWO is also committed to providing regular firmware updates to keep the AM5N compatible with the latest imaging software and accessories.
