TeleVue Coma corrector Paracorr Type 2

Paracorr Type 2

The optical chain is only as strong as its weakest link. Tele Vue's groundbreaking 82-degree Nagler and 100+ degree Ethos eyepieces set industry standards for the largest, flattest, and best-corrected visual fields. Pairing the Nagler/Ethos revolution with the Dobsonian revolution and Paracorr creates an ideal combination for breathtaking wide and sharp "spacewalk" observing.

Life without Paracorr

Coma, the distortion that turns stars into blurry comets with radial tails, plagues scopes with high speeds. Even a superbly crafted 13" f/4.5 parabola suffers from limited field sharpness due to coma. Previous correction attempts were fraught with limitations, such as complex installation or limited field correction. Dedicated coma correcting eyepieces were another option, but they often compromised on apparent field width.

Life with Paracorr Type-2

Paracorr is a universal corrector that enhances star images across all f-ratios down to f/3, without introducing false color or spherical aberration! With Paracorr, Dobsonian users no longer need to constantly adjust their scopes to keep objects centered for sharp viewing. Simply use a Tele Vue eyepiece, place M-13 at the edge of the field, and witness its full splendor as it traverses your view. Paracorr seamlessly integrates into your focuser like a Barlow lens, minimizing focuser in-travel with its mild 15% Barlow effect. While optimized for Tele Vue eyepieces, Paracorr is also compatible with other brands. Experience the complete revolution by trying Paracorr on your "DobNewt."

Paracorr Eats Coma

Paracorr accommodates both 2" and 1.25" eyepieces. For visual use, insert Paracorr into your focuser like a Barlow lens, and your eyepiece into Paracorr. 1.25" eyepieces utilize Paracorr's low-profile reducing adapter. Paracorr also features threaded compatibility for 2" filters. Achieve optimal coma correction with Paracorr's Tunable Top, ensuring precise adjustment of the field stop location for various eyepieces.

Astrophotography

Paracorr extends its utility to DSLR and CCD cameras. Simply detach the lens assembly from the Tunable Top and attach appropriate threaded accessory tubes and camera mounts. Mount your DSLR or CCD to the Paracorr Type 2 lens assembly for stunning full-frame photos with exceptional star image quality and edge-of-field sharpness. Paracorr acts as a field-flattener, enhancing image quality for all f-ratios down to f/3 without introducing false color or spherical aberration. For focal lengths shorter than 1200mm, some field curvature may occur. We recommend APS size formats for optimum performance.
