Product Description

The Paracorr Type 2 allows separating the optical assembly from the Tunable Top and using it with TeleVue imaging system components to permit use with SLR and CCD cameras. APS size formats 27mm diameter are recommended to minimize field vignetting. Ideal for mirrors as fast as f/3.

Paracorr Type-2 for 2" Focusers

Mount your DSLR or CCD to the Paracorr Type 2 lens assembly and the quality of full frame photos will be spectacular since star image sizes on the image plane can be less than .001" over the full frame for an f/4.5 mirror. Edge-of-field sharpness is further enhanced since Paracorr also acts as a field-flattener. Works on all f-ratios f/3 and slower without adding any false color or spherical aberration! See spot size graphs: PDF or JPG. NOTE: Curves shown are typical for mirror focal lengths in the 1200mm or longer focal length range. For focal lengths shorter than 1200mm, you might find some field curvature. In general, we recommend APS size formats, which would typically yield 90% illumination over a 30mm diagonal chip.

An optical chain is as good as its weakest link. With the development of 82 degree Nagler and 100+ degree Ethos eyepieces, TeleVue offers the largest, flattest and best corrected visual fields in the industry. Combine the Nagler/Ethos revolution, Dobsonian revolution and Paracorr for the ideal mating for spectacular wide and sharp "spacewalk" observing.

Life without Paracorr

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.

Previous attempts to correct for coma have been limited in usefulness. Some correctors were designed mainly for astrophotography, some required difficult installation in the focuser's draw tube. Dedicated coma correcting eyepieces were another approach. However, these were limited to 50 degree apparent fields and would orphan your existing eyepiece collection.

Life with Paracorr

Paracorr is a universal corrector that tightens and intensifies star images on all f-ratios down to f/3! (see spot size graphs: PDF or JPG) 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 fully 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 Plössls, Delites, Panoptics, Naglers, Ethos and Delos eyepieces 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.

Paracorr Eats Coma

Paracorr can be used with both 2" and 1¼" eyepieces. For visual use, slip Paracorr Type-2 into your focuser like a Barlow lens, and your eyepiece into Paracorr. 1¼" eyepieces will make use of Paracorr's special low profile 1¼" reducing adapter. Paracorr is threaded for 2" filters.

Paracorr 2 does the job in Portaball 12.5" f4.8

I finally got out last night to try the Paracorr 2 after 3 weeks of clouds. My Portaball 12.5 f4.8 Dobsonian is a great scope for star hopping fun. But in wide field eyepieces the stars had a lot of coma in the outer half of the FOV. After much research I decided to buy the Televue P2 from All-Star Telescope, very good service and prompt shipping by the way.
I have to say, with the P2, the views in all eyepieces I tried were extremely improved. Eyepieces I tried were 35 Panoptic, 3.7 Ethos, Stellarvue 20 Optimus, Meade 40 SWA series 5000 and the Meade 14 UWA series 4000. Stars were a pleasure to view all across the field out to the last 5% or less of the FOV. Even the first quarter Moon was crisp all over the FOV at high power. The P2 was easy to set up for TV eyepieces and all others when following the instructions on the TV website.
I whole heartily recommend the Paracorr 2 if you have a fast Newtonion telescope.
