Televue 2X Barlow - 1.25"

If you don't compromise optical quality when it comes to your telescope's eyepieces, why should you compromise with a barlow lens? Thanks to Televue's innovative 2-element design, now you can get superb sharpness that matches the performance of TeleVue eyepieces. The Televue BLW-2125 2X Barlow is an achromatic system, but the design gives better color correction over its competitors at the edge of field. Optically corrected down to f/4 for use with fast f/ratio reflectors, the Televue 2X Barlow is parfocal with TeleVue Plossls under 32mm, and provides excellent performance with any scope type.

The Televue 2X Barlow - 1.25" is fully multi-coated, with blackened lens edges and internal anti-reflection threading for excellent contrast. Its 3.75" length allows the TeleVue 2X Barlow to be used in star diagonals and what's more, the barrel is threaded for standard 1.25" filters. As a unique feature, the Televue 2X Barlow has a safety groove. Have you ever dropped a thumbscrew in the dark? No more. The Televue BLW-2125 has a captive thumbscrew which helps hold the Barlow in place should the focuser thumbscrew accidentally loosen!

"Televue's Barlows were envisioned as magnification windows. 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
