iOptron Pier Top Plate for iEQ30 and iEQ45 Mounts (#8032PT-IEQ30)

Custom-build your observing platform with iOptron precision.

The iOptron Pier Top Plate for iEQ30 and iEQ45 mounts is a CNC-machined, 150mm (6") aluminum flange designed for DIY pier builders or anyone looking to adapt an existing tripod or pier for iOptron equatorial mounts. Whether you're assembling a custom concrete pier or retrofitting an older field tripod, this top plate gives you the mechanical interface you need to securely support your iOptron iEQ30, iEQ30 Pro, iEQ45, or iEQ45 Pro mount head—with accurate alignment and rock-solid stability.

Observing Tip:

When building a DIY pier, pairing it with a factory-machined top plate like this ensures proper fit, easier polar alignment, and a secure mechanical interface—critical for long-exposure imaging or unattended automation. It also saves you from the guesswork of aligning bolt patterns or fabricating your own mounting surface.
