The Explore Scientific Pier Extension is designed to raise the Twilight II mount 8" from the tripod to provide extra height for more comfortable observation by taller users, or to give longer refractor OTAs, such as 152mm and 127mm models, more clearance. The addition of the Pier Extension adds valuable height to your rig without sacrificing strength or stability.
