iOptron CEM120 Equatorial Mount

iOptron CEM120 Equatorial Mount

iOptron developed the CEM120 after identifying a growing demand for accurate and stable equatorial mounts that are versatile enough to carry heavier loads are more intricate imaging arrays. The CEM120 has all the advantages of iOptron's innovative "center balance" design such as stability, accuracy, and smooth mechanical performance, while also being able to accept a payload of up to 115 pounds (52 kg). The natural stability of the "center balance" design comes from the concentration of mount and payload weight directly over the center of the pier or tripod.

The high performance of the CEM120 is evident by its low ±3.5 arc second periodic tracking error. To go with the stability feature, the CEM120 employs an advanced cable management system with more ports in more locations to avoid entanglements and limit the chance of broken cables. The CEM120 also contributes some new features to the CEM family such as WiFi and LAN for remote use, and user-friendly, dependable clutches on both axes.
