Increase the power of any 2" eyepiece by a factor of 2x - for example: makes a 30mm eyepiece perform like a 15mm eyepiece
In keeping with our tradition of offering top-notch astronomy gear at great prices, Orion is proud to offer our 2" diameter, 2x Barlow Lens at a very affordable price. Like other 2x lenses, this big 2" model provides a 2-time power-boost to any 2" eyepiece so you can enjoy double the magnification of any 2" ocular. Just insert into a telescope's 2" focuser and then insert any 2" eyepiece into the Barlow to double the power of the eyepiece. Its huge 2"-diameter is optimized to work with virtually all 2" telescope eyepieces such as the Orion DeepView and Q70 lines; and it works well with other brands of 2" eyepieces too. An included 1.25" adapter ensures all your 1.25" eyepieces will work as well. While 2" eyepiece users are often trying to stretch the limits of their telescopes to oobtain 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.
