ZWO AM5 Strain Wave Equatorial Mount Head

The ZWO AM5 Harmonic Equatorial Mount The ZWO AM5 Harmonic Equatorial Mount has been designed specifically for astrophotography enthusiasts and is now the epitome of portability. With its ability to effortlessly accomodate imaging setups weighing up to 13 kilograms sans the need for counterweights this mount can handle small to midsize telescopes and cameras with ease. For those seeking even greater capacity the optional counterweights expand the load-bearing capability to a remarkable 20 kilograms all while maintaining a very light 5-kilogram profile. Traditionally 20kg will require a whopping huge mount weighing itself 20kg and more which was too heavy and bulky to move around. Unlike conventional equatorial mounts that necessitate bulky counterweights which often prove challenging to maintain equilibrium in both right ascension RA and declination DEC when changing the pointing direction the ZWO AM5 revolutionises the game. This mount incorporates the advanced Harmonic Drive speed reducer and a meticulously designed Synchronous belt system. The result is an unparalleled level of precision control boasting a remarkable 300:1 reduction ratio for your imaging rig. Achieving guiding accuracy within the range of 0.5 to 0.8 arcseconds the ZWO AM5 offers an exceptionally low periodic error silky-smooth gearing and impressive torque capabilities rendering the need for cumbersome counterweights commonly associated with traditional German equatorial mounts obsolete. Astronomy-Dedicated Harmonic Drive Speed Reducer The result of their innovative technology that answers to all dedicated astrophotographers’ needs and wants is a mount that boasts very low periodic errors smooth gearing and high torque. The AM5 is born for astronomy. To know that your mount has been vigorously tested and not subject to quality control errors ZWO measures each mount and equips it with the exclusive PE curve aseen in the included performance chart included in each package. The X-axis represents the drive angle. The Y-axis represents periodic errors. The periodic error is stably controlled within20 arc seconds. You can be assured that your mount is tested to succeed. Graphical Insights: To achieve this level of precision a unique PE curve for each mount. The X-axis of this graph represents the drive angle while the Y-axis vividly portrays periodic errors. Rest assured our mounts consistently maintain a stable control of periodic errors within an impressive range of 20 arc-seconds. This commitment to excellence guarantees that your astrophotography experience will be nothing short of exceptional.
