The Ostara Long Body 2x Achromatic Barlow lens doubles the magnification with any given eyepiece, without any noticeable loss in image quality.
Insert the Barlow lens between the eyepiece and the telescope and you will double the magnification. At the same time you will retain the comfortable eye relief of the longer focal length eyepiece. Multi-coated lenses and blackened lens edges result in optimum contrast and image sharpness.
The large lens aperture allows you to use even very long focal length 1.25″ eyepieces without vignetting.
