The Orion 2x 2-Elements Barlow Lens 2" is like other 2x Barlow lenses, and provides a 2x power-boost to any 2" eyepiece so you can enjoy double the magnification of any 2" ocular. Just insert this Barlow into a telescope's 2" focuser and then insert any 2" eyepiece into the Barlow to double the power of the eyepiece. This big Barlow has a 2"-diameter, optimized to work with virtually all 2" eyepieces. An included 1.25" adapter ensures all your 1.25" eyepieces will work with the 2" 2x Barlow Lens!
While 2" eyepiece users often try stretching the limits of their telescopes to obtain wider, low power fields of view, there are many times when more power is needed to tease out detail from a small deep sky object or planet. Orion's 2" 2x Barlow Lens features multi-coated lenses for high contrast and glare reduction. It's even threaded for use with big 2" filters to further enhance your astronomical adventures!
