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 1.25 inch or 2 inch eyepiece, put M-13 at the edge of the field and enjoy resolving its beauty as it drifts across your view. Paracorr is easy to use. It slips into your focuser, just like a Barlow. To minimize focuser in-travel, due to additional length, a mild 15% Barlow effect was designed into Paracorr to effectively push the focus out. Paracorr is recommended for use with all TeleVue eyepieces because our Plossls, Radians, Panoptics, Naglers and Ethos achieve higher levels of aberration correction than competitive models. However, Paracorr is also compatible with other eyepiece makes. Try Paracorr on your “DobNewt.” We think you’ll agree that the revolution is complete.
