About the TeleVue 15mm Plossl Eyepiece - 1.25"...
Since Televue introduced their Plossl TeleVue Telescope Eyepieces in 1980, they have won praise and patents, including a patent in Japan. Tele Vue 15mm Plossl Eyepieces, designed by Al Nagler, have been a recognized benchmark of performance and value in the class of 50 degree apparent field of view telescope mounts. While the Plossls may be the least expensive TeleVue Telescope Eyepiece line, they still enjoy the same care and attention to detail as the 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 TeleVue Telescope Eyepiece value for your dollar.
Diffraction 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 15mm Plossl Eyepieces deliver sharper images than any other brand of 4 or 5 element "Plossl" or Orthoscopic designs. The faster the focal ratio of your telescope, the greater your visual reward for using TeleVue Telescope Eyepieces. Tele Vue Plossls 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 telescope eyepiece field focuses faint star light into perceptible points and allows those with undriven telescope mounts to gaze longer before repositioning the image.
The Tele Vue 15mm Plossl Eyepiece focal plane is placed at the end of the barrel to minimize vignetting. TeleVue Telescope Eyepiece performance with Schmidt-Cassegrains is remarkable since it avoids the image degradation and severe vignetting which occurs when using telecompressors. Long eye-relief and unique adjustable eyeguard for eyeglass wearers.
