Tele Vue 2x Barlow 1.25"

This 1.25" Barlow has been designed by Tele Vue to give you 2x magnifications. This barlow lens has been optimized with parafocalization and fully multi-coated optics. Captive lock screws keep your barlow in place and 1.25" standard filter threads have been added to give you a full range of viewing options.

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 eyepiece aberrations.

Tele Vue Barlows use 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 scopes. They even improve our competitor's 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 our eyepieces. All Tele Vue Barlows now use brass clamp rings for secure, nonmarring holding of eyepieces and accessories.
