![]() ![]() ![]() See our blog post, Paracorr-Newtonian for Visual and Imaging to f/3! Part 2, and Paracorr Type-2 page on our website ( mobile site).Īstronomy Technology Today had Paracorr Type-2 on the cover for the Nov/Dec 2010 issue. Performance improvement over the original Paracorr is most noticeable on all Newtonian/Dobsonian telescopes of f/4.5 and faster. This new Paracorr Type-2, this time designed by Paul Dellechiaie, when inserted into an f/3 Dobsonian makes the stars appear as coma-free as a native f/12 mirror!Ī popular product, Paracorr Type-2 is available in three models: 2″ Photo/Visual for drop-in use in 2″ focusers, the Starlight Integrated Paracorr System (SIPS) which is built into a Starlight Instruments Feather Touch focuser, and a 3″ photo model for integration into fast Newtonian astrographs using sensors over 30mm in diagonal. We decided to re-optimize the Paracorr with a new Type-2 design. By 2009 mirrors had gotten decidedly faster than they were in the late ’80s and some of our eyepieces had significantly different field stop locations (focus positions). To rescue fast Dobsonian telescopes from the curse of coma, Tele Vue’s Al Nagler designed the original Paracorr ( PARAbola CORRector) in 1989.
