Sky-Watcher AZ-EQ5 Pier Extension
The Sky-Watcher AZ-EQ5 Pier Extension elevates your AZ-EQ5 mount head by a crucial 6.3 inches, providing the necessary clearance to prevent long optical tubes from striking the tripod legs when slewing to or tracking objects near the zenith. This simple, robust accessory solves one of the most common frustrations for imagers and visual observers using refractors or long Newtonians on the versatile AZ-EQ5 mount.
6.3 Inches of Added Clearance to Reach the Zenith
When tracking an object passing directly overhead, the length of a refractor's optical tube can cause it to collide with the tripod, interrupting an imaging sequence or preventing observation entirely. The AZ-EQ5 Pier Extension adds 6.3 inches of vertical separation, creating a safe zone that allows your telescope to move freely through the meridian without impact. This modification is essential for anyone conducting all-sky surveys, automated imaging routines, or observing targets at high altitudes.
Improved Ergonomics and Observing Comfort
Beyond collision avoidance, the added height significantly improves the ergonomics of a visual setup, particularly with refractors. The 6.3-inch lift raises the eyepiece to a more comfortable position, reducing the need to crouch or bend in awkward positions during a long observing session. This makes for a more enjoyable and sustainable night of stargazing, especially for taller observers.

Solid Mechanical Interface: Designed specifically for the AZ-EQ5, the extension mates securely to both the mount head and tripod, ensuring a rigid connection that minimizes flexure and preserves the mount's stability.
-
Straightforward Installation: The pier extension installs in minutes using the existing mounting hardware, creating a seamless and sturdy link in your imaging or visual platform.

What is the primary purpose of the Sky-Watcher AZ-EQ5 Pier Extension?
Its main purpose is to raise the AZ-EQ5 mount head by 6.3 inches. This provides critical clearance for longer telescopes, like refractors, preventing them from hitting the tripod legs when pointed at or near the zenith (directly overhead).
Will this pier extension fit my Sky-Watcher EQ6-R or HEQ5 mount?
No. This pier extension is specifically designed for the bolt pattern and base of the Sky-Watcher AZ-EQ5 mount. It is not compatible with other mounts in the Sky-Watcher lineup.
How much height does the AZ-EQ5 Pier Extension add?
The extension increases the height of the mount head by exactly 6.3 inches (16 cm).
Will adding the AZ-EQ5 Pier Extension make my setup less stable?
The extension is engineered from solid metal to be extremely rigid and maintain the stability of the mount. While raising the center of gravity can make any system more susceptible to vibrations from wind, the mechanical connection is solid and will not introduce flexure into the system.
I use a 120mm refractor on my AZ-EQ5 for astrophotography. Is this extension recommended?
Absolutely. A 120mm refractor is a perfect example of an optical tube that risks a tripod collision when imaging targets near the zenith. The 6.3 inches of clearance provided by the AZ-EQ5 Pier Extension is precisely what you need to ensure your telescope and camera can track through the meridian without interruption.
Is the AZ-EQ5 Pier Extension difficult to install?
Installation is very straightforward. You simply unbolt the AZ-EQ5 mount head from the tripod, place the pier extension on the tripod, and then bolt the mount head onto the top of the extension using the same central bolt.
