William Optics Adapter Plate for Mortar Tri-Pier

This adapter plate acts as a bridge between your William Optics Mortar Tri-Pier and a Vixen-style mount. It provides a secure, vibration-resistant interface that ensures your telescope or imaging rig remains stable during long exposures.

This plate is specifically engineered for Vixen-style mounts. While it is designed to fit the William Optics Mortar Tri-Pier, it will work with any mount head that utilizes the standard Vixen connection interface.

The three-bolt configuration creates a wider, more balanced distribution of weight compared to single-point attachments. This design significantly reduces micro-vibrations, which is critical for maintaining sharp focus during astrophotography.

No, the plate is machined from aircraft-grade aluminum, which offers an excellent strength-to-weight ratio. It is lightweight enough that it won't noticeably impact the portability of your Mortar Tri-Pier setup.

You will typically need a standard hex key (Allen wrench) to secure the three bolts. The installation process is straightforward and can be completed in a few minutes without specialized equipment.
