Double your viewing power
The X-Cel LX 2X Barlow lens is a perfect way to double the magnification of eyepieces you already have. Just screw the Barlow lens into your telescope's standard eyepiece mount, then slide your eyepiece into the top of the Barlow lens. A brass compression ring with thumbscrew holds the eyepiece in place, turning the entire assembly into a more powerful eyepiece for your telescope. Premium apochromatic optics yield sharp, high-contrast images of the moon, nearby planets and other celestial phenomena.
