Alstar 1.25" 3-Elements 2X Barlow Lens - Bundle with - 1.25" NBPF 12nm Filter

The 1.25" 3-Element 2x Barlow Lens triples the power of any 1.25" telescope eyepiece. It's an ideal accessory for high-power lunar and planetary observation, as well as lunar and planetary imaging when used with a solar system camera or webcam. Use this handy magnification-boosting Barlow for up-close views of Mars, ringed Saturn, and gigantic Jupiter, or to study craters of the Moon in exquisite detail. The extra power boost provided by this Barlow Lens is especially helpful when used with short focal length telescopes that would otherwise not be able to achieve the desired magnification with very short focal length eyepieces. The 2x Barlow features an enhanced 3-element lens design which preserves the sharpness and contrast of your telescope and telescope eyepieces. The lens elements are fully multi-coated with anti-reflection coatings, and edge-blackened to provide maximum light throughput and optimal image contrast.
