iOptron Permanent Pier

iOptron Permanent Pier – 900mm Height with CEM120 Mounting Plate (#8038-900)

A rock-solid foundation for serious observatories and remote setups.

If your observing or imaging setup deserves a permanent home, the iOptron 900mm Permanent Pier (#8038-900) delivers the stability, durability, and compatibility you need. Built from thick-walled aluminum alloy and engineered for high-load support, this pier eliminates the vibration and flex that often plague lighter setups. Designed with iOptron’s CEM120 mounting pattern in mind, it offers a secure and stable platform for a wide range of mounts—either directly or with an adapter.

Whether you're building a remote-controlled observatory, installing a telescope on a deck or concrete slab, or just want to ditch the tripod for something more permanent, this pier provides an uncompromising foundation.

Key Features:

• Thick-Walled 5mm Aluminum Tube Construction:
  Heavier-duty than most field tripods or piers, the 5mm wall thickness ensures excellent vibration damping and superior load support—ideal for large optics and extended imaging sessions.

• Integrated Side Struts for Anti-Flexure Rigidity:
  Four welded aluminum support braces connect the main pier tube to the base plate, dramatically reducing lateral flex and movement under heavy or offset loads.

• Tall Observatory-Grade Design (900mm / 35.4"):
  Perfect for permanent installations, the pier offers plenty of vertical clearance for long optical tubes, camera trains, and accessory stacks.

• Precision CEM120 Mounting Plate:
  Comes pre-drilled for the iOptron CEM120 mount and compatible with other iOptron and third-party mounts using optional adapters.

• Multi-Mount Compatibility:
  Use this pier with the following mounts (directly or with adapters as noted):

  • CEM120 – fits directly

  • CEM70, CEM60, iEQ45 Pro/iEQ45 – requires optional adapter

  • AZ Mount Pro, MiniTower, MiniTower Pro – use with Star Knob & Center Post Set (#8340-PIER)

  • Paramount MyT – fits directly, no adapter needed

  • Astro-Physics 400, 600E, Mach1GTO – use with iOptron Tri-Pier Adapter (#8036-AP)
    Note: Due to the larger mounting plate size, some mounts may have telescope clearance issues during low-altitude slewing.

• Ideal for Concrete Pads or Observing Platforms:
  The flat base and welded flange make it easy to permanently bolt the pier to a concrete slab or deck with proper anchor hardware (not included).

Observing Tip:

Installing a permanent pier doesn’t just eliminate setup time—it also improves long-term imaging results by removing variables like tripod leg flex or accidental bumps. If you're imaging at high focal lengths or using automated remote control systems, a permanent pier like this one is one of the most cost-effective upgrades you can make.
