The 25mm, 20mm, 15mm, 11mm, and 8mm Plossls round out the focal lengths for various observing from deep sky to planetary. They work best with Tele Vue Powermates to effectively double the number of focal lengths in your collection. Far superior to eyepieces usually provided as standard with most instruments.
Since TeleVue introduced their Plossls in 1980, they have won praise and patents, including a patent in Japan. Tele Vue Plossls, 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 Plossls may be Tele Vue'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.
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 Plossls deliver sharper images than any other brand of 4 or 5 element Plossls or Orthoscopic designs. The faster the focal ratio of your telescope, the greater your visual reward for using Tele Vue 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 field focuses faint star light into perceptible points and allows those with undriven mounts to gaze longer before repositioning the image.
