About this product

Model:  iop_cem60-ec_7201
Part Number:  7201

Latest model with increased payload and high precision RA encoder!

The new updated CEM60EC features an increased payload of 27kg / 60lbs! *

The mount's centre-balanced equatorial mount (CEM) puts the weight of the payload at the centre of gravity for greater natural stability. This enables the mount to be surprisingly light, compared to its payload. Polar aligning is also quick and accessible because the polar scope is not blocked by the declination shaft.

The CEM60EC is equipped with the iOptron's most advanced GOTONOVA® GOTO technology, making it one of the most powerful and accurate GOTO mounts available. Its database includes over 200,000 objects.

Other features include an adjustable counterweight bar, magnetically loaded gear system, gear switches on both R.A. and DEC axes, screw/worm type latitude adjuster and integral cable management system.

Note 1: If you buy the mount with an iPolar we will install it free of charge smiley

Note 2: Tripod/Pier not included.
