Televue 2 inch Big Barlow with 1.25 inch adapter.
The Tele Vue 2x - 2" Big Barlow Lens is designed to fit a 2" barrel and accepts a 2" or a 1.25" eyepiece. It will double the magnification you would get with that eyepiece and telescope combination, without the Barlow lens. The Big Barlow is ideal for Newtonian scope owners. It will be parfocal with both 2" and 1" eyepieces, in this application.
