HUGE OFFER BARLOW 2X TELEVUE 1.25'' TELESCOPE OPTICS
The item is new and in excellent condition in its original box without any defects at all and this is an amazing one-time offer!

Concept: "I originally designed the TeleVue Barlow line to complement the high performance of our 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 will not degrade your telescope's optics. Anyone telling you otherwise is using outdated information. Moreover, the highly regarded Nagler 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

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. They even improve their competitor's eyepieces and telescopes!

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

The 2x 1.25" Barlow performs beyond your expectations. Features include parfocal-ization, 1.25" filter threads, captive lock screws that won't fall outand full multicoatings.
