High-Power 1.25 Inch 2X 4-Element Barlow Lens

• This 4-Element 2x Barlow will give your 1.25" tele eyepieces a power-doubling magnification boost.
• Sophisticated fully multi-coated, 4-element lens design renders exquisite images without introducing additional chromatic aberration for crisp, color-correct views.
• Enjoy twice the power while maintaining comfortable eye and edge sharpness of longer focal length eyepieces.
• Great for high-magnification lunar and planetary observations and astrophotography.
• Brass compression ring keeps eyepieces securely installed without scratching, and the barrel is threaded for use with 1.25" Orion filters.

This premium 1.25" Barlow lens will give all of your 1.25" tele 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 / 2 = 12.5). Using this simple formula, you can easily determine how each of your 1.25" tele 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. 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.
