Extra 2.5 lb. counterweight for Counterweight Bar Assemblies (#94191 & #94192)
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 8"and 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.
