Description
This 2" 2x achromatic ED Barlow lens effectively doubles the magnification of each eyepiece. This barlow uses two-element, fully-multicoated ED lenses with blackened edges to maintain excellent color correction and sharpness. In addition, the barlow element itself can be removed from the extension tube of the unit and threaded directly into 2" eyepieces with a standard 2" filter thread to increase the magnification of an eyepiece by 1.5x. So this barlow can effectively make a single eyepiece give three different magnifications. Made by GSO in Taiwan.
Any barlow lens typically pushes the focus point of a telescope outwards, so there is a small chance that you may not be able to reach focus with all your eyepieces in your specific telescope.
