Pier Extensions & Tri-piers

Maximum Freedom of Movement: Pier Extensions for Long Telescopes A common problem when photographing or observing objects high in the sky (the zenith) is that the back of the telescope or camera can hit the tripod legs. This phenomenon, also called a ‘zenith collision,’ is not only frustrating during an automatic session, but can also lead to mechanical damage to your mount's motors. At Telescoop.nl, we offer the solution with our Pier Extensions (also called extension columns). These robust accessories raise the mount head by 15 to 40 centimeters, allowing your telescope to ‘swing’ freely without obstruction.

Especially when using long apochromatic refractors (APOs) or Schmidt-Cassegrain systems on an equatorial mount, a pier extension is an indispensable upgrade. Brands such as Sky-Watcher and ZWO have developed specific extension columns that fit seamlessly with their popular mounts, such as the EQ6-R or the AM5. The design focuses on maximum rigidity; a good pier extension adds height without introducing the dreaded vibrations that can ruin your recordings.

Tri-piers: The Hybrid between Column and Tripod For the astronomer who seeks the stability of a fixed column but does not want to give up the portability of a tripod, the Tri-pier the ultimate outcome. A tri-pier combines the central column of a column with the folding legs of a tripod.

  • Superior Stability: By placing the center of gravity of the mount directly above the central column, vibrations are dampened much faster than with a traditional tripod.

  • Compact on Travel: The tri-piers of iOptron and ZWO are often collapsible into a surprisingly compact package, making them the ideal base for mobile astrophotography with heavier payloads.

  • Leveling: Many of our tri-piers are equipped with adjustable feet, allowing you to create a perfectly level foundation for your mount even on uneven terrain.

The Right Choice for Your Setup
At Telescoop.nl, we select our pier extensions and tri-piers based on mechanical tolerances and materials. Whether you're looking for a lightweight carbon extension column for your travel mount or a heavy-duty steel tri-pier for a fixed mount in the backyard, the right foundation determines the precision of your tracking. In combination with other Mounting Accessories make sure your hardware is never the limiting factor on a clear night. Our experts are happy to advise you on the compatibility between your mount and the various column options, so you can explore the zenith with confidence.
