Tele Vue 20mm Plossl 1.25" Eyepiece

Because it's crafted to meet Al Nagler's rigorous standards, the Tele Vue Plossl 20mm Eyepiece offers superior performance at an accessible price point. This high-quality eyepiece is designed for both near and deep-sky observations, producing a relatively low magnification on most Optical Tube Assemblies (OTAs). Constructed with diffraction-limiting high-index glass lenses, this eyepiece features a 4-element/2-group configuration. This design ensures light remains on-axis, significantly reducing astigmatism and edge-aberrations across the entire 50-degree apparent field of view. The Tele Vue Plossl 20mm Eyepiece boasts fully multi-coated optics, blackened lens elements, and anti-reflection threads. These elements work in harmony to enhance contrast, improve light transmission, and limit light loss, providing you with clear, sharp images of celestial objects. With a generous 14mm eye relief, this eyepiece allows for a comfortable viewing experience. Users can slightly back off from the eyecup, reducing the risk of accidental contact with the eyepiece lens, which could cause vibrations and disrupt views. Designed for fast-focal ratio OTAs, this versatile eyepiece features a standard 1.25" barrel, making it compatible with the most popular size of focuser and accessories. It also includes a convenient fold-down rubber eyecup for added comfort during extended viewing sessions. As part of the Plossl series, this model is parfocal with all Tele Vue Group 'B' eyepieces. This means you can switch between compatible eyepieces without having to refocus, saving time and minimizing vibrations. Experience the universe through the lens of the Tele Vue Plossl 20mm Eyepiece, a reliable and affordable choice for astronomy enthusiasts.
