Using accessories such as cameras, Lens Shades, Tele-Extenders and the 2" Diagonal will affect the balance of your Celestron Schmidt-Cassegrain telescope. Counterweights restore proper balance, increasing ease in handling and improved tracking accuracy.
Once the Bar Assembly is in place, counterweights can be attached to it and moved along its length, as well as perpendicular to it, for better dynamic balancing. Each Counterweight Bar Assembly comes with mounting hardware and one 2.5 lb. weight.
