About the TeleVue 2X Barlow - 1.25"...

Properly designed Barlow lenses 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.

Ā 

Tele Vue Barlow Lenses 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 telescope. TeleVue Barlow Lenses even improve our competitor''s telescope eyepieces and telescopes!

Ā 

"I originally designed the TeleVue Barlow Lens line to complement the high performance of our TeleVue Telescope Eyepieces. Only 2 elements of high index glass were required to reduce all aberrations to well below the airy disc in an f/4 system. It has taken a good 15 years, but I think we''re finally laying to rest the popular myth of the "degrading Barlow." In a 1997 Sky & Telescope review, Terrence Dickenson wrote "...Technology has erased the old objections. A modern Barlow lens will not degrade your telescope''s optics. Anyone telling you otherwise is using outdated information. Moreover, the highly regarded Nagler TeleVue Telescope Eyepieces and their clones have built-in Barlows - ample evidence that the lens is not some detrimental intruder." Thanks Terry, I couldn''t agree more." --Al Nagler
