Cassini 3x Barlow Coated Telescope Lens

The Cassini 3x Barlow Lens increases the focal length of a telescope three (3) times. The result is three (3) times the magnification with the eyepieces you already have. If you have three (3) eyepieces, adding one (1) Barlow will in effect expand your eyepiece collection to six (6) without having to purchase an additional three (3) eyepieces. Format: 1.25 Design: Barlow Focal Length: 3x Lens coating: Coated lens
