The Counterweight Bar Assembly is a metal rail that runs the length of the telescope tube. It attaches to both the front and
rear cells of an 11" SCT.
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.
