TeleVue Plossl 20.0mm eyepieces EAP20 have won praise and patents,

including
a patent in Japan.
Tele Vue Plössl 20.0 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.
