iOptron Counterweight

This counterweight is specifically engineered for use with the iOptron CEM60 and iEQ45 equatorial mounts. It is not designed for universal use across all telescope mounts, so please verify your mount model before purchasing.

We generally advise against using this weight on mounts from other manufacturers. The center hole diameter and locking mechanism are precision-engineered for specific iOptron shafts, and using it on incompatible equipment could compromise the stability of your setup.

Yes, the counterweight includes a secure locking mechanism to ensure it stays firmly in place on the counterweight shaft. This is essential for maintaining the balance of your telescope during long-exposure astrophotography.

While 20 pounds is a standard increment for the CEM60 and iEQ45 series, your specific telescope load may require multiple weights or a different configuration. Always calculate your total payload—including the telescope, camera, and accessories—to determine if you need one or more 20-pound weights for proper balance.

Aluminum provides a durable, corrosion-resistant solution that is easier to handle than traditional cast iron or steel weights. It offers the necessary density for balancing while maintaining a sleek, professional finish that matches the aesthetics of your iOptron mount.
