William Optics Tripods & Piers

William Optics tripods and piers give a mount a stable, level base. The Pier Mount 90 is a pier for a permanent or semi-permanent setup.

The Low Latitude and High Latitude WO Vixen Style Base Mounts are bases matched to your observing latitude range, and the Mortar pier head adapters fit the William Optics Mortar pier to iOptron, Vixen-style and Takahashi mounts or to a standard 3/8" screw. Pick the adapter that matches the base of your mount.
