Paracorr VISUAL, with Tunable Top

All Newtonian/Dobsonian telescopes can benefit from using a Tele Vue Paracorr (Parabola Corrector) to eliminate coma in the image. Coma is the effect that makes off-center stars appear like little comets (it becomes more apparent as stars move closer to the edge of the field). Any Newtonian/Dobsonian telescope will benefit from the use of Paracorr, but those from f/3.5 to f/5.0 will see the greatest results. This model Paracorr has the largest lenses possible to prevent any vignetting, even when using the 31mm Nagler Type 5. The tunable top permits positioning all Tele Vue eyepieces for optimum performance
