Vixen R200SS Coma Corrector PH 90 deg converter Distance front surface to sensorThe Vixen corrector PH is a 3 element Wynne corrector for demanding astrophotography applications. It is specifically designed for the Vixen R200SS Newtonian reflector, but is also suitable for other optics with similar specifications. The optical design consists of 3 lenses in 3 groups. The corrector provides excellent correction of system induced coma of parabolic mirrors and the resulting spherical aberration. The corrected field has a diameter of
