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.

Paracorr is recommended for use with all Tele Vue and compatible eyepieces. It 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.

Paracorr is designed to work properly only with parabolic mirrors in Newtonian or Dobsonian telescopes. The visual (PCV-2000) and photographic (PLA-2001) models are the same optically but the visual model has a larger output lens to prevent vignetting when using a 31mm Nagler Type-5.

Both types require a 55mm +4mm optimum back focus for CCD or film plane.
