While the Plössls may be TeleVue's least expensive eyepiece line, they still enjoy the same care and attention to detail as their most expensive.

The faster the focal ratio of your telescope, the greater your visual reward for using Tele Vue eyepieces. Tele Vue Plössls feature full multicoatings for greatest light transmission and contrast. Blackened lens edges and internal anti-reflection threads tweak the last bit of contrast for maximum image detail.

The eyeguard's sliding action allows for positioning the soft rubber eyeguard at the ideal height to suit the observer's preference.

While the Plössls may be TeleVue's least expensive eyepiece line, they still enjoy the same care and attention to detail as their most expensive.

Using more expensive high-index glasses to reduce astigmatism and lateral color at the field's edge, Tele Vue Plössls deliver sharper images than any other brand of 4 or 5 element \"Plössls\" or Orthoscopic designs. The faster the focal ratio of your telescope, the greater your visual reward for using Tele Vue eyepieces. Tele Vue Plössls feature full multicoatings for greatest light transmission and contrast.

Tele Vue Plössls, designed by Al Nagler, have been a recognized benchmark of performance and value in the class of 50° apparent field of view eyepieces. While the Plössls may be TeleVue's least expensive eyepiece line, they still enjoy the same care and attention to detail as their most expensive. While it's easy for other manufacturers to vie for the lowest price, Tele Vue continues to believe that quality, performance and consistency will ultimately reward you with the most value for your dollar.\u003c\/p\u003e\n\u003cp\u003eDiffraction limited \"on-axis\" performance is a given. Using more expensive high-index glasses to reduce astigmatism and lateral color at the field's edge, Tele Vue Plössls deliver sharper images than any other brand of 4 or 5 element \"Plössls\" or Orthoscopic designs. The faster the focal ratio of your telescope, the greater your visual reward for using Tele Vue eyepieces. Tele Vue Plössls feature full multicoatings for greatest light transmission and contrast. Blackened lens edges and internal anti-reflection threads tweak the last bit of contrast for maximum image detail. The sharper field focuses faint star light into perceptible points and allows those with undriven mounts to gaze longer before repositioning the image.\u003c\/p\u003e\n\u003cp\u003eFor a bit more than generic brands, you can own genuine Tele Vue Plössls.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe 55mm focal length has the largest true field possible for 2\" eyepiece holders - 3 times the true field area of any 1¼\" eyepiece.
