Tele Vue BIG Paracorr – Type 2 (3inch)
Tele Vue’s 3″ BIG Paracorr Type-2, designed by Paul Dellechiaie, extends the Paracorr type 2’s optical benefits for imaging applications by amateurs and professionals using CCD formats as large as 52mm diagonal and paraboloids as fast as f/3. Back focal length has been extended to 80mm to allow for additional accessories to be placed in the optical path. The 5.1″ length optical assembly is topped with a “stop” flange having 3.40″-24 pitch threads to mount camera adapters and spacer tubes (available later).
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. (3″ BIG Paracorr Type-2 requires adapter and tunable top for visual use). 1¼” eyepieces will make use of Paracorr’s special low profile 1¼” reducing adapter. Paracorr is threaded for 2″ filters.
