This Half Pillar provides a 9" extension between the counterweight shaft or longer tube refractor and the tripod legs. In several positions at lower latitudes with the counterweight shaft or just using a longer tube instrument at zenith, the tripod legs can interfere with the proper movement of the telescope. Many users with a longer optical instrument may enjoy the gain in the instrument's elevation from the ground to make viewing more comfortable when viewing objects high in the sky.
