Celestron Counterweights
Celestron counterweights are specifically matched to the unique counterweight shaft diameters of the different models of Celestron mounts. There are presently three different counterweight shafts in use between the Advanced VX, CGEM, CGEM DX, and CGE Pro mounts. Larger counterweight may slip over the counterweight shaft of a smaller mount; however, they may be prone to flopping around when crossing the meridian or even slipping on the shaft. We strongly suggest that you follow that manufacturers recommendations unless otherwise stated in the individual product descriptions.
