Product Description


Orion Deluxe Off-Axis Guider for Astrophotography 05521

The Orion 2" Telescope Eyepiece Extension Tube gives extra focuser "back travel" that is sometimes needed to achieve focus with certain eyepiece and telescope combinations. This extension tube is made from machined, anodized aluminum, has two locking thumbscrews and is threaded for filters. Since more back travel is often needed for short-range terrestrial viewing or with use of a field flattner, focal reducer lens, or coma corrector, Orion offers 1.25" and 2" models which fit 1.25" and 2" eyepieces respectively. Each adds 2" of length extension.
