Introducing iOptron's latest CEM26 center-balance equatorial mounts, designed with portability in mind. Weighing only 4.5kg, this compact mount can support a 12kg payload, boasting an impressive 2.6 mount weight to payload ratio. The CEM design centers the mount and payload weight directly on the tripod's center, ensuring natural stability.

In addition to its natural stability, the CEM26 offers features for convenience and functionality, including a positive lock gear engagement system, built-in Wi-Fi for seamless connectivity, and recordable permanent periodic error correction (PPEC) to repeat optimal PEC training sessions. The mount also delivers precise pointing and accurate tracking, setting a new standard for compact equatorial mounts.

The center-balanced design features an adjustable counterweight bar to prevent obstruction with the tripod and enables quick and accessible polar alignment since the polar scope is unobstructed by the declination shaft.

The CEM26 also boasts the latest advanced GOTONOVA® GOTO technology, making it one of the most powerful and accurate GOTO mounts available, with a database of over 212,000+ objects. The Go2Nova® Hand Controller is user-friendly, with a large 4-line LCD screen simplifying the process of setting telescopes and locating objects.

The CEM26 is accompanied by a 1.5" heavy-duty stainless steel tripod, but note that a polar scope is not included.
