ZWO AM5N Harmonic Drive Mount with TC40 Carbon Fiber Tripod – Precision, Portability, and Power for Astrophotography
The ZWO AM5N is a cutting-edge harmonic drive mount designed for astrophotographers who demand high precision, impressive payload capacity, and intuitive control. With a lightweight yet powerful design, this mount is ideal for deep-sky imaging, planetary photography, and visual observation. Whether you’re setting up at home or traveling to a dark-sky site, the AM5N provides an easy-to-use, highly portable solution for capturing the night sky.
Harmonic Drive Technology – Ultra-Smooth Tracking with No Backlash
Unlike traditional worm gear mounts, which can suffer from backlash and periodic error, the AM5N uses a strain wave harmonic reducer for smooth tracking and precise control. This eliminates backlash, reduces mechanical wear, and ensures more consistent long-exposure imaging.
With a periodic error of just ±10 arcseconds, the AM5N provides excellent tracking. When paired with autoguiding, it can achieve sub-arcsecond accuracy, delivering pinpoint star images in deep-sky astrophotography.
Heavy-Duty Mode – Enhanced Performance for Large Payloads
For those using heavier telescopes, the AM5N includes a heavy-duty mode that optimizes the mount’s torque and tracking performance. This feature is particularly useful when imaging with setups over 22 pounds.
In standard mode, the mount operates with a balanced level of torque, ideal for lightweight to mid-range setups. Heavy-duty mode increases motor drive power, improving performance for heavier payloads and maintaining precise tracking for larger telescopes. This allows the AM5N to reach its full 44-pound payload capacity when using a counterweight while still delivering smooth operation.
High Payload Capacity Without Counterweights
One of the biggest advantages of the AM5N is its ability to support substantial payloads without requiring counterweights. The mount can handle up to 28.6 pounds without counterweights, making it well-suited for small to medium-sized refractors, Newtonians, and astrographs.
For larger optical tubes, the mount can support up to 44 pounds with a counterweight. This flexibility allows users to configure their setup with minimal extra equipment while maintaining a stable platform for long-exposure imaging.
USB-C Port – Not a Power Pass-Through
The AM5N includes a USB-C port, but it is important to note that this port is strictly for data communication. It does not function as a power pass-through for the mount.
The USB-C port is used for firmware updates and PC control via ASCOM or INDI, but the mount itself must be powered separately using the 12V DC input. This is crucial for users planning their power setup, as attempting to power the mount via USB-C will not work. A dedicated 12V power source is required for proper operation.
Dual-Mode Operation – Equatorial and Alt-Azimuth Flexibility
The AM5N can operate in both equatorial and alt-azimuth modes, making it a versatile choice for astrophotography and visual observing.
Equatorial mode is the preferred setting for long-exposure astrophotography, as it compensates for Earth’s rotation and prevents field rotation. Alt-azimuth mode is ideal for visual observation, planetary imaging, and electronically assisted astronomy, providing simple and intuitive tracking without the need for polar alignment.
Switching between the two modes is quick and does not require additional tools or accessories.
Seamless Control – ASIAIR, WiFi, and Hand Controller
ZWO designed the AM5N with multiple control options to fit different astrophotography workflows.
- The ASI Mount App allows for wireless control via WiFi or Bluetooth, providing an easy way to manage slewing, tracking, and alignment from a smartphone or tablet.
- The included hand controller allows for manual adjustments and fine-tuning without needing a mobile device.
- Full ASIAIR compatibility enables a completely wireless astrophotography experience with no excess cables.
- PC control via ASCOM and INDI allows for automation using third-party software such as NINA, Stellarium, and TheSkyX.
These options give users the flexibility to control the mount in the way that best suits their needs, whether through mobile devices, a physical hand controller, or full PC automation.
ZWO TC40 Carbon Fiber Tripod – Stability Without the Weight
The TC40 carbon fiber tripod is an excellent companion for the AM5N. It is both lightweight and strong, providing a stable platform without adding unnecessary weight.
- Weighs only 5.5 pounds but supports up to 110 pounds.
- Folds down to 19.6 inches for easy transport.
- Carbon fiber construction dampens vibrations to minimize imaging blur.
- Maximum height of 31.5 inches, with optional pier extensions available for increased height.
This tripod is an excellent choice for users looking for a highly portable, stable, and vibration-resistant platform for their astrophotography mount.
