	Which Celestron counterweights work with which mounts?

Answer

Here are tables showing Celestron counterweight model numbers versus mounts for current and some recent Celestron mounts. These are for counterweights offered by Celestron separately from the mount.

These matches are by shaft-hole size. In use, diameters of the weights and payloads of the mounts should also be taken into consideration.

NOTE: Some of these counterweights are no longer available from Celestron.

94185	2	1 /2” (12mm)	CG-3 (AstroMaster)
