The Vixen Coma Corrector is designed to eliminate coma aberration that easily occurs in the parabolic mirror of reflective telescope, making it possible to take sharp astrophotographs even the edge part.
A Wynne type 3-element in 3-group design. Corrects coma aberration from parabalic mirrow surfaces. Minimize occurrence of spherical aberration.
A broad 44mm diameter circle, which covers a 36mm x 24mm full frame DSLR, and delivers sharp images over the entire imaging field.
A large 50mm aperture lens allows for ample edge of field illumination.
The same anti-reflective AS coatings, which are used in Vixen's high end VSD 100f/3.8 astrograph, are used to take advantage of 99.9%. In order to take advantage of the characteristics, we suggest you use Wide Photo Adapter 60 and Light Baffle Hood together.
Applicable to all Vixen R200SS telescope. Old type R200SS telescope can also be renewed to f/3.8 high speed astrograph too. With bright edge R200SS telescope, by correcting aberration from parabolic mirror surfaces, the corrector delivers bright sharp pinpoint star images to the edge of the broad imaging circle.
