Barlow lenses offer an easy, economical way to increase the magnification range of your eyepieces, and Celestron carries a number of these highly useful lenses. A Barlow lens doubles the magnifying power of your eyepiece by doubling its effective focal length.
The lens unit varies the power obtained with any given eyepiece while maintaining excellent image quality. Their precise corrections for spherical and chromatic aberrations at all photo-visual wavelengths result in sharp, high-resolution performance on telescopes of any optical design.
The Meade #128 3x Short-Focus Barlow 1.25" is a high-power compact Barlow - ideals for systems with limited focus travel. Triple the power of your eyepiece with this high-quality short telenegative Barlow.
