This powerful 5x Barlow lens meets the magnification requirement of all telescope systems with ease. The Orion High-Power 5x Barlow lens consists of 4 lens elements five times the magnification power of a 1.25 inch telescope eyepiece (32 mm), thus showing higher performance than 2x or 3x Barlow lenses. The Orion High-Power 5x Barlow lens is made of a high-quality 4-element lens construction and preserves the optical quality of your telescope and telescope eyepieces, while allowing for enormous 5x magnification. The lens elements of the Barlow lens are fully multi-coated with anti-reflective coatings to ensure maximum light transmission for bright, high-contrast images. The lenses are also blackened at the edges to ensure maximum contrast and sharpness. The frame of the Orion High-Power 5x Barlow lens with 4 lens elements and with 1.25 inch (32 mm) is made of solid aluminium with a non-slip rubber surface. The 1.25" receptacle has a threaded inside for use with Orion 1.25" eyepieces and image filters. The inside of the receptacle of this high-power 5x Barlow lens is also roughened to avoid internal reflections. The brass ring clamp ensures a secure hold of all inserted 1.25" telescope eyepieces (32mm) without causing damage or scratches, and keeps all eyepieces used with the 5x Barlow lens in a near new condition. Add the Orion High Power 5x Barlow lens to your range of accessories for all those occasions where you need the greatest possible magnification power! Weight: 7 ounces (198.45 g).
