iOptron Pier Top Plate For CEM60/70

iOptron Pier Top Plate for CEM60 and CEM70 Mounts – #8032PT-CEM60

If you're building a permanent observatory or modifying an existing pier for a more stable platform, the iOptron Pier Top Plate #8032PT-CEM60 offers a professional-grade mounting solution for iOptron's larger equatorial systems. Designed specifically for the CEM60 and CEM70 series mounts, this precision-machined 6" (150mm) top plate allows for direct integration with your custom pier or heavy-duty tripod.

Whether you're pouring your own concrete base, upgrading a roll-off observatory setup, or simply seeking a stiffer mounting interface, this adapter plate ensures a precise and secure connection.

Designed for Stability and Versatility

Made from thick, durable metal, the 8032PT-CEM60 plate provides a rigid interface between your mount and pier, minimizing flexure and vibration for better long-exposure imaging and slewing stability. The mounting bolt pattern is designed to accommodate:

• iOptron CEM60

• iOptron CEM70
  (When used with the center post included with those mounts)

This plate is ideal for users who want to mount their CEM60 or CEM70 to:

• A custom steel or concrete pier

• A non-iOptron permanent pier or fixed base

• A retrofitted third-party tripod with a flat mounting platform

Important Notes on Compatibility

Low Latitude Operation Warning:
Due to the relatively small base diameter of the CEM60 and CEM70 mount heads, operation at low latitudes (below ~20°) may be affected when using this plate. If you're observing from near the equator, consider using iOptron’s extended latitude wedge options or contact Astronomics for specific installation guidance.

Requires center post: This top plate is not a direct-mount surface. It must be used with the center post that comes with the CEM60 or CEM70 mounts for proper mechanical coupling and azimuth adjustment.

Specifications

• Top Plate Diameter: 6" (150mm)

• Material: Precision-machined metal (anodized finish)

• Mount Compatibility: CEM60, CEM70 (with center post)

• Application: Custom piers, fixed bases, third-party tripod conversions

• Weight: Minimal additional load on your support structure

Observing Tip:

If you're setting up a permanent or semi-permanent observatory, eliminating vibration is critical for imaging. A custom steel pier topped with the correct iOptron pier adapter—like the #8032PT-CEM60—can vastly outperform even premium tripods in terms of rigidity and damping.

Final Thoughts

The iOptron Pier Top Plate for CEM60/CEM70 (#8032PT-CEM60) bridges the gap between your high-performance mount and your custom pier setup. With proper installation, it delivers the rigid, repeatable alignment needed for permanent observatories and remote setups alike.
