Properly balance your optical tube assembly with all its accessories on CEM120 and CEM120EC equatorial mounts with this iOptron 22 lb Counterweight. It has a thumbscrew that allows the weight to be secured anywhere along the counterweight shaft's length to achieve the precise balance required for smooth tracking.
A flawless match to the existing weights, conforming to the highest standards of fit and finish. Substantial in the hand and perfectly sized to the shaft, The locking screw is a joy to use particularly with a properly sized Allen wrench. Once in position it is a force multiplier to the performance of the CEM120. Buy one and you may find yourself releasing the gears just to see and feel the incredible smoothness as you push the weights through the swing arc. Few things are so mesmerizing. But that is insignificant compared to the fast, the very fast free shipping. The best available according to an unpublished study. Highest recommendation for the weight and the shipping.
