iOptron 2.5kg Counterweight for CEM60 and iEQ45 Mounts

Essential Balance for iOptron Mounts

This 2.5 kg counterweight is built for iOptron CEM60, CEM60EC, iEQ45 Pro and iEQ45 equatorial mounts. It provides the mass needed to balance telescopes and cameras for stable long-exposure astrophotography. A secure locking screw with pin allows precise positioning along the shaft. The weight reduces motor strain and vibration during imaging sessions.

For Astrophotographers Using Compatible iOptron

Owners of the listed CEM60 or iEQ45 models who need to offset heavy optical tubes will benefit from this 2.5 kg addition. It also fits any mount with a 28 mm diameter counterweight shaft. Buyers with different shaft diameters or lighter setups requiring less mass should look at other options.

28 mm Shaft Compatibility Decides Fit

The counterweight mounts on a 28 mm diameter shaft, which is standard on the named iOptron models. Verify your mount’s shaft size before purchasing; a different diameter means this weight cannot be secured. This single measurement determines whether the part works with your equipment.
