The CEM60-EC Center-Balanced Equatorial Mount from iOptron features an innovative weight distribution design coupled with precise extended tracking capabilities to create a mount ideally suited for astrophotography or long-term observation. Its center-balanced design puts the optical tube weight directly over the mount's center of gravity which gives it better stability and a greater payload capacity over other EQ mounts. Additionally, the counterbalance shaft length is adjustable to keep it from interfering with whatever pier or tripod is being used.
The Right Ascension worm wheel is equipped with highly precise digital encoders which track the periodic error (PE) inherent in any drive and constantly adjusts the drive speed, in real time, to eliminate the errors, bringing the average PE to less than 0.5 arc seconds. This precision error correction allows for long-exposure astrophotography or other layering techniques that require shorter exposures with filter or other accessory changes. In addition to astroimaging, the extended tracking accuracy makes long term observation of specific objects or areas of interest easier.
For set-up and alignment, the CEM60-EC comes with the AccuAligning Illuminated Polar Scope. The mount is designed so that the declination shaft doesn't block the AccuAligning scope, which makes it accessible at all times for checking or correcting the polar alignment. A built-in 32-channel GPS receiver sends information such as location and local time to the Go2Nova controller for faster and easier set-up.
Included with the mount is the Go2Nova 8407+ controller. This handheld computer guider has a database of over 349,000 objects and is flash updateable from the iOptron website with firmware updates that increase its accuracy and adds celestial objects. The database includes the planets, galaxies, star clusters, quasars, and nebulae; as well as seven astronomical catalogs including Messier and NGC IC. It also has stars, comets, asteroids, constellations, and can store up to 60 user-defined objects to easily find and go-to their favorite objects. The mount has nine slew speeds up to 3.75°/second and can be manually controlled for quick observations.
A hard carrying case with die-cut custom-fit foam comes with the mount and is designed to hold and protect it during transport or storage.
