STEP 7. Install Counterweight(s)
iEQ75-GT comes with two 16.5 lb (7.5 kg) stainless steel counterweights (CWs). Use one or both
CWs as required for your particular OTA. Additional CW(s) may be needed to balance a heavier OTA
(Optional CWs are available from iOptron).
CSUTION: The mount must be at the zero position when the counterweights are being installed. The
Zero Position is the position with the CW shaft pointing toward the ground, as shown in Figure 15. Use your
hand controller to move the mount.
