Tele Vue EAP-20.0 overview

  • 1Description

Engineered to Al Nagler's uncompromising standards but at an entry-level price, the long-focal length Tele Vue Plossl 20mm Eyepiece produces a relatively low magnification on most OTAs for both near and deep-sky observations.

It 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. This model of the Plossl series is parfocal with all Tele Vue Group 'B' eyepieces, allowing you to change compatible eyepieces without having to refocus — saving time and limiting vibrations.

    Tele Vue EAP-20.0 reviews

    Plossl 20mm Eyepiece (1.25") is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from Great eyepiece When I purchased my TeleVue TV-85 refractor telescope it came with one of these 20mm Plossl oculars. When I realized how well the eyepiece performed I purchased another so I could pair them for binoviewing. The views through this eyepiece are clear and sharp with good contrast. I have many other eyepieces but this is one of my favorites. Highly recommended.

    Rated 5 out of 5 by from Excellent ocular I received this eyepiece with a new TeleVue TV-85 refractor telescope. It is a wonderful eyepiece. Clear, bright, contrasty and sharp with decent eye relief. I ordered an extra one so I can use them with binoviewers. Recommended.
