The primary function of the Orion 1.25-inch Extension Tube is to provide an additional 2 inches of focuser back travel. This is crucial when your telescope's focuser cannot reach the necessary inward position to achieve sharp focus with certain eyepieces or accessories, especially during terrestrial observations or when using specific camera setups for astrophotography. By extending the optical path, the tube allows the focuser to operate within its optimal range, ensuring clear and precise images.

Ensure it is correctly inserted and secured in the focuser, and that your eyepiece/accessory is also securely fastened within the extension tube. The added 2 inches of back travel should allow your focuser to reach the necessary focal point.
