Tele Vue Barlows: "An Optically Perfect Window"

"A Little Nagler Goes Into Every Tele Vue Barlow"

Properly designed Barlows do wonderful things. First, they amplify power while retaining the eyepiece`s eye-relief. Second, they slow the telescope`s f/#, which improves eyepiece sharpness. Third, the designer can introduce compensations for eyepiece aberrations. Tele Vue`s 2" 2x BIG Barlow, 1 1/4" 2x and 3x Barlows were envisioned as magnification windows. Multi-coated high index glasses assure optimum aberration correction, exceptional contrast and virtually no light loss. Tele Vue Barlows achieve their design goals even when tested by the fastest scopes. They even improve our competitor`s eyepieces and telescopes!

For eyeglass wearers, the Big Barlow is perfect for doubling the power while retaining the eye-relief of 2" Tele Vue eyepieces such as the 55mm Plossl, 35mm and 27mm Panoptics (requires use of Panoptics Barlow Interface) and 20mm Nagler Type 2.

Our design approach includes mechanical conveniences. The Barlows are parfocal with our eyepieces and the BIG Barlow includes a parfocal 2" - 1 1/4" adapter. The BIG Barlow is threaded for 48mm filters and has a captive lock-screw. Both 1 1/4" Barlows are threaded for 1 1/4" filters.

Tele Vue Quality:  Why compromise any optical link? 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 before leaving our hands for yours.

User Report:  "Tele Vue`s "Big Barlow" doubled the power but, like an optically perfect window, never gave any other indication that it was in the light path. The airy disc and surrounding diffraction rings were perfect, with no sign of astigmatism or coma. It will provide outstanding optical performance with all your eyepieces." -Alan Dyer Astronomy Magazine

Best Barlow you can buy!

By Luis Vazquez on October, 17th 2009

Ive used this barlow for a few months now and I can honestly state that it was a purchase well made. The fit and finish of this barlow is exceptional and its optics complement every EP Ive used with it. It even appears to be parfocal with most TeleVue Plossls. It has become a usefull addition to my collection and is used more often than not. Highly recommended...

To Barlow or Not to Barlow

By Kimball Corson on October, 17th 2009

This is a great barlow . . . if you like barlows.

Highly recommended accessory

By James A. Edwards on October, 17th 2009

This is a very well made 2 Big barlow which I have used over a long period of time for planetary use primarily. I have also recommended it to people with a limited number of eyepieces as a way to double your collection and still get a great 2 accessory in the process. I highly recommend this Barlow, without a doubt!
