Telescope-Mounts-ZWO AM5N Harmonic Drive Equatorial Mount Head (2024 Version)

More Powerful and Precise
ZWO’s original AM5N already sported an impressive payload capacity to mount weight and low periodic error, and with the AM5N they’ve pushed the limits even further! Halving the periodic error from the previous generation, ZWO has improved the already great tracking performance of this platform with a guaranteed periodic error of +/- 10 arcseconds, for easier guiding and better results. They’ve managed to achieve this while also increasing the payload capacity from about 28.5 lbs. to 33 lbs., for a bit of extra headroom! Finally, ZWO has introduced Heavy Duty Mode, in which the slew speed is reduced to increase the payload capacity. This reduction in slew speed may help preserve the power of your portable battery, which is especially useful in cold climates.

Quality-of-Life Upgrades
With cable management and connectivity improvements, the AM5N is better than ever! Now with Bluetooth functionality, you can connect wirelessly to the mount without needing to disconnect your smart phone/tablet from WiFi, allowing you to jump back-and-forth between controlling the AM5N and using your device. While previously this functionality was available through Station mode, this updated connectivity promises to be much easier to setup and use! To save your cables (and device ports!) from image session ending snags, ZWO has integrated cable routing to seamlessly run mount control and power to the DEC saddle internally. This allows you to share the AM5N’s 12V power, and control the mount via the USB-C port, with your telescope mounted devices like the ZWO ASIAIR — all without crossing the DEC axis! This keeps your imaging setup tidy and safe, so you can focus on imaging and not wrangling cables. Please Note: The USB port on the AM5N’s DEC saddle is not a passthrough, and is only an alternate way to connect to and control the mount.

Harmonic Gear and Synchronous Belt Core
The heart of ZWO’s AM5N mount is the innovative harmonic drive speed reducer and synchronous belt system. This gives the AM5N precise control without backlash concerns, as well as high payload capacity without the need for counterweights! For those looking for even more lifting strength a user supplied counterweight shaft and counterweight can be added via the M12 threaded connection on the bottom of the mount, which will increase the payload capacity by 11 lbs. for a total of 44 lbs.! Please Note: The foam case provides space for a counterweight shaft to simplify transport should you wish to add one, however a counterweight shaft is not included.

Two Mounts in One
Whether you’re interested in precisely setting up your mount for tracking deep sky targets without rotation, or a simple set-up-and-go process for visual observation or field rotation forgiving astrophotography, the AM5N is the mount for you! Able to be converted from equatorial to alt-azimuth mode with a simple latitude adjustment and the included hand controller or mobile app, you can switch from imaging to observing in a snap — and with a red/green status LED, you can easily keep track of what mode your mount is in. Make you backyard imaging mount your grab-and-go dark site observing mount, with the ZWO AM5N!

Multiple Means of Control
When it comes to controlling the AM5N, you have the versatility to be as hands-on — or hands-off — as you want! The included hand controller provides some simple controls for those looking to take a more manual, self-guided, tour across the night sky, as well as a means to change the from EQ to Alt-Az or vice-versa. If you’re looking for a more information rich, guided, or remote control experience, the AM5N can connect with the ZWO StarGazing app via WiFi or Bluetooth for access to a list of curated celestial targets, GoTo functionality, or the impressive and immersive digital planetarium selection tool — SkyAtlas — as well easy access to mount settings. For more advanced users, this mount also features a USB port for PC and ASIAIR connectivity! Known iPad Compatibility – The mount is compatible with iPads running iOS 12 and up, including iPad/iPad mini, iPad Air, and iPad Pro. To use the Sky Atlas app feature, you will need a device with at least 6 GB of RAM

Lockless Azimuth, 0-90° Latitude, Adjustments
New to the AM5N is a lockless azimuth adjustment system, allowing you to easily make fine adjustments when you need to — all without needing to fiddle with any levers or bolts! Four powerful springs work together with the adjustment knobs to keep your alignment locked in place once you’re done adjusting, making polar alignment a cinch. This ZWO AM5N mount also comes with a wide range of latitude adjustability, spanning 0-90°! For the first gear, adjust the pitch angle grip to achieve between 0° to 60°. For the second gear, loosen the hex-head screw and adjust the pitch angle grip to get between 45° and 90°. Not only does this allow astroimagers to use the AM5N in alt-azimuth mode, it also allows those in both low and high latitude locations to use this ZWO mount when in equatorial mode.

Power Failure Protection
ZWO has equipped the AM5N EQ/Alt-Az mount head with a power brake design. This is incredibly important for the safety of your imaging equipment. If there is a sudden power failure during use, the AM5N mount power failure protection system will prevent your telescope from falling and being damaged by triggering a brake to stop the mount’s movements.

ASIAIR Plus Compatible (Sold Separately)
There is another wireless control solution available for this AM5N mount, and it’s called the ZWO ASIAIR Plus! This user supplied small wireless module allows you to control the mount with your smartphone or tablet, in addition to a whole host of other ZWO ecosystem cameras and accessories (sold separately). Thanks to this mount’s saddle mounted power and data ports the ASIAIR system shines even brighter on the AM5N when it’s combined with a power supply capable of driving everything the mount and control system need, like the Apertura 12V 10A DC Power Supply – 5.5×2.1mm (sold separately). Simply plug your user supplied high amperage power supply into the AM5N and connect the ASIAIR to the saddle for a tidy, DEC axis crossing free, wireless control solution!

Please note that this is mount is compatible with all versions of the ASIAIR!

Ideal for On the Go Imaging or Backyard Observing
Thanks to its compact body and impressive performance, this ZWO AM5N is the perfect mount for trips to dark skies or for imaging from the backyard. The mount head itself weighs only 12 lbs., making it easy to travel with. Fitted with built-in Bluetooth, an intuitive joystick hand controller that adds WiFi connectivity, and fully ASIAIR compatible, operation is simple and straightforward! For backyard observing, take advantage of the high payload for larger telescopes that are more difficult to travel with. Wanting to use your favorite third party software to control your AM5N? Not a problem! Easily connect this mount to your PC via the onboard USB-B 2.0 port. With features like these, the ZWO AM5N Harmonic Drive Equatorial Mount earns our High Point Scientific Classification Badge of New Wave Harmonic!
