Stellarvue Extension Tube ET475

Do you need just a little more traveling room for your binoviewer to achieve focus? The Stellarvue ET475 provides a full 4.75" of additional back focus. Featuring all aluminum anodized parts with safety rubber grip, non-marring brass compression ring, and filter thread on insert tube. The Stellarvue ET475 is created for 2" focusers and contains a beveled insert which improves the snugness of the fit as the lock screw is tightened.
