The AM3N is upgraded from the AM3 with internal cable management.\u003c\/p\u003e\n\u003cp\u003eWith a traditional EQ mount, it can be difficult to keep balance in RA and DEC directions while being difficult to carry and store. The AM3N Harmonic Drive EQ mount has a large load capacity of 17.6 lb. (8kg) without a counterweight and 28.6 lb. (13kg) with a counterweight (not included) while only weighing in at 8.6 lb. (3.9kg). Stability is essential for operation, and ZWO found a way to balance portability with functionality with the AM3 mount.\u003c\/p\u003e\n\u003cp\u003eThe internal structure of the AM3N Harmonic Drive EQ Mount is optimized with the strain wave gear reducer and synchronous belt. This optimization brings more accurate control and a fantastic reduction ratio of 300:1. In addition to having a large load capacity without needing counterweights, the AM3 mount is considered multi-functional and can be used as both an equatorial and alt-azimuth mount. To add to its versatility, the AM3 can be controlled using either the included hand controller or WiFi\/Bluetooth.\u003c\/p\u003e\n\u003cp\u003eZWO has designed the AM3N mount head to be an astrophotographer’s dream mount! While incredibly portable, it also has many features, like the two control options, the harmonic drive speed reducer and synchronous belt, and more that make this mount a must-have tool for your imaging sessions. Check out some of these features below!\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eDual Mount Style\u003c\/strong\u003e\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eZWO has designed the AM3N mount with the capability of switching between equatorial or alt-azimuth mount modes. You can switch the mode through the included hand controller or through the app on a smartphone\/tablet. The body of the mount comes with a status light indicator that will indicate whether the mount is in an equatorial or alt-azimuth mode. The red light signals the AM3 is in EQ mode and the green light signals the mount is in Alt-azimuth mode. The equatorial mode is great for tracking and imaging celestial objects while the alt-azimuth mode works well for observations.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eHarmonic Drive Speed Reducer and Synchronous Belt\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eThe incorporated Harmonic drive speed reducer and synchronous belt allow this mount head to have precision control. While a traditional equatorial mount requires counterweights for use, this ZWO mount's harmonic drive speed reducer and synchronous belt eliminate the need for counterweights, though they can be added if desired (an M12 thread interface is available for compatible, user-supplied counterweight shafts). Having this design allows for more accurate control and a reduction ratio of 300:1. If counterweights are added, then it should be secured on a counterweight shaft that is no more than 20cm in length.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003c\/span\u003e\u003ca class=\"prodimgpopupbutton\" id=\"prodpopuplink7\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e0-90° Latitude Adjustment Range\u003c\/strong\u003e\u003cbr\u003eThis ZWO AM3N mount comes with a latitude adjustment range of 0-90°.

Not only does this allow astrophotographers to use the AM3 in alt-azimuth mode, but it also allows those in both low and high-latitude locations to use this ZWO mount when in equatorial mode.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eASIAIR Plus Compatible\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eThe ZWO ASIair Plus (not included) offers another wireless control solution for this AM3N mount.
