1. CEM26 Overview
The iOptron
®
CEM26 and CEM26EC mount is the next-generation compact center-balance
equatorial mounts. Like their predecessors, the CEM26 is designed with portability in mind, weighing in at
only 10 lbs, it can support up to a 26lb payload an incredible 2.6 mount weight to payload ratio. The key to
enable such ratios is the CEM design focuses the mount and payload weight directly on the center of the
tripod rendering “natural stability”.
Building on the legacy of earlier CEM models, we have added features for convenience and
functionality. A positive lock gear engagement system (easy to use even when wearing gloves), Built-in Wi-
Fi enabling unparallel connectivity and recordable permanent periodic error correction (PPEC) to repeat
optimal PEC training sessions (real time PEC on the CEM26EC). Regarding functionality the CEM26 and
CEM26EC delivers precise pointing and accurate tracking (PE <0.3 arcsec rms on the EC model). The
212,000 object library ensures you’ll never run out of targets to see or image. The CEM26 and CEM26EC
set the new standard for compact equatorial mounts.
The mount has an integrated electronic polar finder scope known as the iPolar, or an AccuAlign
TM
optical polar scope. The iPolar ensures the accurate alignment of a telescope, even when the pole star is
obscured.
The iOptron CEM26 mount uses the new Go2Nova® 8409 hand controller to navigate the night sky.
This incredible technology helps observers find celestial objects with the aid of the mount's 212,000+ object
database! For those looking for a telescope that has the capability of tracking and finding beautiful night sky
objects, this mount is a must have tool.
