Astro-Physics 10 lb. Stainless Steel Counterweight - 1.875"
Astro-Physics 10 lb. Stainless Steel Counterweight - 1.875"The 10-Pound Stainless Steel Counterweight - Fits a 1.875-Inch Shaft - by Astro-Physics:
Astro-Physics counterweights are precision machined from 303 stainless steel. A bronze sleeve is press-fit into the center hole to prevent marring of your counterweight shaft as you adjust the position of the counterweights. The weights slip easily onto the counterweight shaft and are secured in position with a large hand knob/brass pin assembly. The brass pin will not mar your shaft.
Keep in mind that you can adjust the position of the weights to counterbalance varying loads. However, the addition of a guidescope, camera or other heavy accessories may necessitate an additional counterweight. If you plan to mount your catadioptric, Newtonian or any other scope on your Astro-Physics mount, figure that you will need a counterweight total equal to approximately 80-percent of the weight of your tube assembly and accessories.
