Add an additional Celestron 12lb counterweight to help balance your equipment payload. Severely out-of-balance loads cause strain on the motors and gears, may affect tracking and increase current load to PMDC motors causing premature failure.
The locking knob is styled to match the original counterweight supplied with Celestron's VX mount. This weight will also fit the Celestron CGEM, CGEM II and CGX mounts, however the knobs appear different. We also sell the 11lb CGEM counterweight with the correct knob.
