Product description The CEM120EC Center-Balanced Equatorial GoTo Mount from iOptron features an innovative weight-distribution design coupled with precise extended tracking capabilities to create a mount ideally suited for long-exposure astrophotography and observation. Its center-balanced design puts the weight of the optical tube assembly (OTA) and accessories directly over the mount's center of gravity, which gives it better stability and a greater payload capacity over other mounts. Additionally, the counterbalance shaft length is adjustable to keep it from interfering with whatever pier or tripod is being used.This upgraded model of the CEM120 is engineered with highly precise encoders to bring its tracking error down to less than 0.15 arcsec, with a Real-Time Periodic Error Correction (RPEC) system that constantly monitors the accuracy and automatically correct errors to improve tracking and GoTo accuracy. In addition to improving astrophotography/imaging results, the extended tracking accuracy makes long-term observation of specific objects or areas of interest easier.Included with the mount is the Go2Nova 8407v2 controller. This handheld computer guider has a database of over 350,000 objects and is flash updatable from the iOptron website with firmware updates that increase its accuracy and add 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, and constellations, and can store user-defined objects to easily find and go to favorites. The mount has nine slew speeds up to 4°/second and can be manually controlled for quick observations. Adding to its ease of use, iOptron outfitted the mount with a 32-channel GPS receiver that sends highly accurate location coordinates, date, and time information automatically to the hand controller for more precise setup. The CEM120EC also comes with built-in WiFi and LAN interfaces to make wireless or wired remote control fast and easy. - Mount
