Barlow Lens, 2x, 1.25"
Double your telescope's magnification with this high-quality 2x Barlow lens from Orion. This achromatic Barlow lens is multi-coated and only 3" long. Just insert it into your telescope's 1.25" focuser (or diagonal), and add an eyepiece. On 1200mm Dobsonian telescopes, this Barlow increases the magnification of a 25mm eyepiece from 48x to 96x and increases the magnification of a 10mm eyepiece from 120x to 240x. In addition, the internal baffles in the housing eliminate reflections and increase contrast. This lens is great for planetary viewing. Orion #8711.
