TeleVue Barlow Lens Powermate 2x 2'' (16731)

The TeleVue Powermate 2x 2" Barlow lens is a premium magnification accessory designed to deliver sharp, high-contrast images across the entire field of view. Based on Al Nagler's innovative 4-element design, the Powermate maintains the full eye relief of long focal length eyepieces even at higher powers, providing both comfort and clarity. The unique optical system consists of a negative doublet and a positive "pupil-correcting" doublet, which together eliminate the common limitations of traditional Barlow lenses by restoring field rays to their original direction. This results in pure magnification without vignetting or loss of image quality.

This Powermate is ideal for astronomers who want uncompromising image quality and flexibility, whether for visual observation or astrophotography.
