TeleVue Plossl 15.0mm Eyepiece EAP-15 have won praise and patents, including a patent in Japan. Tele Vue Plössl 25.0 eyepieces, designed by Al Nagler, have been a recognized benchmark of performance and value in the class of 50 degree apparent field of view eyepieces. While the TeleVue Plössl 20 eyepieces may be Tele Vue least expensive eyepiece line, they still enjoy the same care and attention to detail as our most expensive.
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 Plossl eyepieces deliver unusual sharp images. The faster the focal ratio of your telescope, the greater your visual reward for using Tele Vue eyepieces. TeleVue Plössl eyepieces 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.
The TeleVue Plossl EPL 25mm, 20 mm, 15mm, 11mm and 8mm Tele Vue Plossl eyepieces round out the focal lengths for various observing from deep sky to planetary. They work best with TeleVue Powermates to effectively double the number of focal lengths in your collection. Far superior to eyepieces usually provided as standard with most instruments.
