Super deal on a Super Eyepiece!
Up for sale: a Tele Vue 1.25" Plossl Telescope Eyepiece 20mm in original box, perfect condition
This stellar eyepiece is made using diffraction-limiting high-index glass lenses in a 4-element/2-group configuration to keep light on-axis and reduce astigmatism and edge-aberrations across its entire 50° apparent field of view. Fully multi-coated optics, blackened lens elements, and anti-reflection threads complement the optical components to improve contrast and light transmission, while limiting its loss. Its generous 14mm eye relief allows users the room to back off slightly from the eyecup for a more comfortable viewing experience with a reduced risk of accidental contact with the eyepiece lens which can cause vibrations and interfere with views. Ideal for fast-focal ratio OTAs, the eyepiece features a standard 1.25" barrel to be compatible with the most popular size of focuser and accessories, with a convenient fold-down rubber eyecup.
