iOptron Counterweights

iOptron counterweights and shafts balance the telescope on iOptron equatorial mounts. Weights run from 1 kg for the SmartEQ and 1.35 kg, through 2 kg, 2.5 kg and 4.5 kg models for mounts from the CEM26 and GEM28 to the CEM40, GEM45 and CEM70, up to 10 kg for the CEM120, including a low-latitude version.

Counterweight bars and extensions fit the HEM27/HEM44, CEM26 and GEM28, ZEQ25/CEM25 and SGP/HAE mounts, plus a SkyTracker Pro counterweight package.
