Sky-Watcher AL-EQ55i Pier Extension 8.5 in

Product purpose

The Sky-Watcher AL-EQ55i Pier Extension is an accessory built specifically for the EQ-AL55i mount. It raises the mount head by 8.5 inches to improve viewing angles and prevent obstructions during astronomical sessions. This extension suits observers who need extra clearance for the counterweight bar or who operate at extreme latitudes. It provides a stable, higher platform for the existing mount.

Build integration

The extension bolts directly to the EQ-AL55i mount without adapters, creating a rigid connection that minimises vibrations. By lifting the mount head, it frees up space around the counterweight bar, allowing smoother rotation and reducing the risk of collisions with tripod legs or surrounding objects. The added height also makes polar alignment and eyepiece access more comfortable during long imaging runs. No modification to the mount itself is required.

Capacity and headroom

The 8.5 inch rise delivers the extra clearance needed for high-latitude observing and for optical tubes that demand a higher centre of gravity. It handles the full load of the EQ-AL55i mount and attached telescope without flex, keeping guiding performance steady. Once the extension is fitted, further height adjustment is not possible, so users requiring variable elevation will need a different solution. The fixed rise covers the most common clearance shortfalls for this mount.
