The Orion 2-inch Precision Centering Extension Adapter allows you to accurately center any 2-inch eyepiece or accessory in a 2-inch telescope focuser. Most standard 2-inch focusers use a metal thumbscrew to secure an inserted eyepiece or accessory in place, which pushes the inserted barrel laterally, i.e., off-center. This can make observations less than ideal, and can reduce the usefulness of collimating tools. The Orion 2-inch Precision Centering Extension Adapter employs a nylon helical compression mechanism that precisely centers the inserted accessory as it is tightened in place. The adapter fits in all 2-inch focusers and will not scratch your inserted accessories with its nylon compression ring.

The Orion 2-inch Precision Centering Extension Adapter is especially useful for centering 2-inch eyepieces and imaging cameras on the center axis of a telescope's light path. The adapter also provides 1.7-inches of extension which is often needed when a star diagonal is not used with refractor or cassgrain telescopes. It's also ideal with reflector telescopes for critical centering of a collimating device.

Made of machined, anodized aluminum with a knurled twist-lock ring, the Precision Centering Extension adapter adds 1.7 inches (43mm) of extension.
