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.

TeleVue 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.

A modern Barlow will not degrade your telescope's optics. Anyone telling you otherwise is using outdated information.

"Properly designed Barlows do wonderful things. First, they amplify power while retaining the eyepiece's eye-relief. Second, they slow the telescope's f/ratio which improves eyepiece sharpness. Third, the designer can introduce compensations for eyepiece aberrations. Televue's 2" 2x BIG Barlow was envisioned as a magnification window. Multi-coated high index glasses assure optimum aberration correction, exceptional contrast and virtually no light loss. Televue Barlows achieve their design goals even when tested by the fastest scopes. They even improve our competitor's eyepieces and telescopes!" --Al Nagler
