NOTE: William Optics has changed the pier post color to anodized Red, not black as pictured.

Included iOptron EQ Mount Plate is compatible with the CEM40, GEM45, CEM60, and CEM70 mount heads. We recommend this tri-pier for the CEM40 and GEM45, and the iOptron Tri-pier, which has a larger diameter, for the CEM70.

This Tri-Pier from William Optics is a great accessory for those looking for the stability of the pier, but the portability of a tripod.

The Mortar tri-pier is 100% CNC machined from high quality 6061T aluminum and stainless steel. The design with replaceable base plates makes this WO Tri-Pier compatible with a range of mounts with optional base plate adapters.
