product description
The Vixen Corrector PH is an unprecedented corrector lens system which is designed to excellently eliminate aberration from parabolic mirror surface. Star images can be distorted at the edge of field of view by coma aberration when photo is taken by reflector (Newtonian) tube alone. This Corrector PH delivers surprisingly sharp pinpoint image of stars to the edge of field of view.
This product is applicable not only for photography, but also for visual observation.
Features of the Corrector PH
- The adopted Wynne 3-group 3-element optical design extraordinary corrects coma-aberration from parabolic mirror surface, and eliminates spherical aberration. This realizes extremely uniform sharp pinpoint image of stars not only in the center but also to the edge of field of view.
- This delivers very sharp images over the entire field of view with a large image circle (Dia. 44 mm) which covers full-frame format.
- The provided Vixen's AS-coating (Maximum transmission rate at 99.9 % per surface) on all lens surfaces and excellent matte inner surface finish minimizes light loss and generation of ghost and flare.
- High quality control is assured by production in Japan and 100 % inspection for elimination of the lens eccentricity.
