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.
