iOptron Counterweight for CEM120

No, this counterweight is specifically engineered for the CEM120 mount. It features a 1.5-inch bore size designed exclusively to fit the shaft diameter of that specific model.

The bore size determines whether the weight will slide securely onto your counterweight shaft. Because the CEM120 uses a specific shaft diameter, this 1.5-inch bore ensures a precise fit, which is critical for maintaining balance and preventing the weight from slipping during operation.

Yes, this unit is optimized to maintain balance even when your mount is positioned for low-latitude observation. This helps ensure your imaging setup remains stable and tracks accurately, regardless of your geographic location.

The number of weights required depends entirely on the total payload of your telescope, camera, and accessories. You should calculate the total weight of your imaging train and balance it against the mount's capacity to determine if a single 22-pound weight is sufficient or if you need to stack additional units.

This counterweight includes a 1-year limited warranty from iOptron, covering defects in materials and workmanship under normal use.
