Add an additional Celestron 11lb 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 CGEM mount. This weight will also fit the Celestron VX, CGEM II and CGX mounts, however the knobs appear different. We also sell the 12lb VX counterweight with the correct knobs.
