SKU: PVL-2008

New Version for 2008! 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. Paracorr is a universal corrector that tightens and intensifies star images on all 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 Tele Vue eyepiece, put M-13 at the edge of the field and enjoy resolving its beauty as it drifts across your view. Paracorr is recommended for use with all Tele Vue eyepieces because our Plössls, Radians, Panoptics, and Naglers achieve higher levels of aberration correction than competitive models. However, Paracorr is also compatible with other eyepiece makes. The Paracorr can be used with both 2" and 1 1/4" eyepieces, as well as with your 35mm camera body. For visual use, slip Paracorr into your focuser like a Barlow lens, and your eyepiece into Paracorr. 1 1/4" eyepieces will make use of Paracorr's special low profile 1 1/4" reducing adapter. Paracorr is threaded for 2" filters. TeleVue
