The counterweight system consists of a narrow black anodized aluminum dovetail bar that extends along the underside of the telescope optical tube, all appropriate mounting hardware, and a 2.5 pound dovetail-mounted counterweight. The appropriate black anodized mounting plates and stainless steel hardware for your particular scope are used to attach the dovetail bar to existing holes in the front and rear cells of the scope at the 6 o’clock positions. A Phillips head screwdriver is the only tool required.

The long threaded rod with a dovetail at one end is slipped onto the installed dovetail bar. The 2.5 pound counterweight is threaded onto the rod and the position of the rod along the telescope tube and the distance of the weight below the tube is adjusted until the accessory load is balanced. A large no-tool handle on the threaded shaft securely locks the rod in place at any desired location along the dovetail bar.

If extremely heavy loads need to be balanced, optional extra 2.5 pound and 5 pound threaded counterweights are available. The dovetail bar measures 18” in length. The total weight of the counterweight system is 5 pounds.
