STEP 4. Attach Dovetail Adapter

Install the Mounting Plate onto the iEQ75-GT mount. Both Vixen (included) and Losmandy-D dovetail saddles can be used. The mounting-hole distribution on the Mount Plate is shown in Figure 14.

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.
