Properly designed Barlows do wonderful things: They amplify power, slow the telescope's f/# (improving eyepiece sharpness), and give designers the opportunity to compensate for telescope eyepiece aberrations.

This Tele Vue 2x 1.25" Barlow uses multi-coated high index glasses for optimum aberration correction, exceptional contrast with virtually no light loss. Observed performance is aberration free, even when tested with f/4 telescopes. This barlow lens improves the performance of all eyepieces and telescopes!

Compromise image quality in any part of the optical chain and you've compromised every part! Tele Vue product design and execution deliver consummate satisfaction. Every Tele Vue Barlow must pass the same rigorous f/4, full field testing as all of their telescope eyepieces. All Tele Vue Barlows now use brass clamp rings for secure, non marring holding of eyepieces and accessories.
