Feature premium 4-element lens design; the Astromania High-Power 5x Barlow will render exquisite images without introducing additional chromatic abberation while providing a monstrous 5x power boost
The Barlow lens elements are fully multi-coated with anti-reflection coatings to ensure maximum light throughput for bright; crisp views; the lenses are also edge-blackened to further maximize contrast and sharpness
The 1.25 barrel is internally threaded for use with Astromania 1.25inch eyepiece and imaging filters; the inside of the 5x High-Power Barlow's barrel is also glare threaded to help prevent internal reflections
Almost 3D Observing Possible: A binocular viewer turns your telescope into binoculars; unlike the common and rather un-natural one-eye observing way; you can observe in a fully relaxed manner without squinting and experience a stronger sense of space
Equipped with Two Additional Eyepieces: Two 1.25-inch 37mm Plossl eyepieces are firmly secured in place with compression rings without scratching them; a stereoscopic binocular viewer requires two eyepieces with the same focal length and optical design
