TeleVue Plossl 55.0mm eyepieces EPL-55 have won praise and patents,

including
a patent in Japan.
TeleVue Plössl 55.0 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 55 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,
TeleVue Plossl eyepieces
deliver unusual sharp images. The faster the focal ratio of your
telescope, the greater your visual reward
for using
Tele Vue eyepieces.
Tele Vue 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 55 mm focal length has the largest true field possible for 2"
eyepiece holders - 3
times the
true field area of any 1-1/4"
eyepiece.
