TeleVue Paracorr Visual PCV-2000 was created by
Al Nagler.
TeleVue Paracorr Visual PCV-2000 provides new and improved

way of coma correction.
Coma makes stars look like blurry comets whose tails point out radially from the center of the field. The faster your scope's speed, the worse the effect. All
parabolic mirrors used in
Newtonian reflecting telescopes are limited in field sharpness due to coma. Even a perfectly made
13" f/4.5 parabola has only about 0.1 degree diffraction limited field.
TeleVue Paracorr Visual is a universal corrector that tightens and intensifies star images on f-ratios from f/3.5 to f/8 without adding any false color or spherical aberration! You no longer have to constantly shift a Dobsonian to keep objects centered for sharp viewing. Using a
TeleVue eyepiece, put M-13 at the edge of the field and enjoy resolving its beauty as it drifts across your view.
TeleVue Paracorr Visual fits 2" focusers, but takes both
2" eyepieces and
1 1/4" eyepieces with
adapter (included). Also includes
TeleVue Paracorr Tunable Top which allows the user to set the distance between the eyepiece's field stop and the
Paracorr lens for optimum aberration control.
TeleVue Paracorr Visual is threaded for 2" filters.
