This premium 1.25" Barlow lens will give all of your 1.25" telescope eyepieces a power-doubling magnification boost with amazing image quality. The Orion High-Power 1.25" 2x 4-Element Barlow Lens provides superior performance compared to standard Barlow lenses thanks to its deluxe features and 4-element design which minimizes chromatic and spherical aberrations while preserving image sharpness and contrast.
As its name implies, the High-Power 2x Barlow doubles the magnifying power of any 1.25" eyepiece, essentially dividing the eyepiece's focal length by a factor of 2. For example: using a 25mm eyepiece in the High-Power 2x Barlow provides the same magnification you'd normally get from a 12.5mm eyepiece (25 Çú 2 = 12.5). Using this simple formula, you can easily determine how each of your 1.25" telescope eyepieces will perform when inserted in the High-Power 2x 4-Element Barlow Lens. A 20mm ocular will behave like a 10mm eyepiece; a 6mm eyepiece will provide the magnification of a 3mm eyepiece, and so on.
Since the Orion High-Power 2x Barlow features a sophisticated, 4-element, fully multi-coated lens design, it will provide better color correction and less distortion than 2- or 3-element Barlows. This means your power-boosted observations will be optimized in regards to sharpness, clarity, and brightness for a great viewing experience. View contrast is maximized thanks to a blackened interior and blackened lens edges which eliminate internal glare and off-axis reflections.
The Orion High-Power 2x Barlow can be used with longer focal length eyepieces to obtain a more comfortable view with better eye relief and edge sharpness than a lower focal length eyepiece. In general, lower focal length eyepieces feature a very small eye lens, which can be a hassle to peer or squint through. By using a longer focal length eyepiece in the Orion High-Power 2x Barlow, you'll enjoy twice the magnifying power while maintaining the comfortable eye relief and sharp field edge of the longer focal length ocular.
A non-marring brass compression ring inside the High-Power 2x Barlow helps keep any inserted 1.25" eyepiece free of scratches and thumbscrew gouges. A stylish rubber grip exterior provides a sure grip, and the 1.25" barrel features a safety recess to keep the Barlow Lens from falling out of a focuser or diagonal should the retaining thumbscrew become loose during stargazing sessions. The Barlow's 1.25" barrel is conveniently threaded for use with 1.25" Orion filters.
Don't compromise your investment in a quality telescope and eyepieces with a lesser Barlow. Step-up to the premium Orion High-Power 1.25" 2x 4-Element Barlow Lens and see the difference!
