Vixen - Corrector PH (for R200SS)add this item to shopping cartThis product is highly recommended
Code: 37237
Advanced Field flattener (Coma Correction) lens for rich field astrophotography with classic R200SS f/4 reflector telescopes


This new Japanese designed and manufactured high quality corrector lens system is for astrophotography applicable to parabolic mirrors.

Features:

Wynne type 3-element in 3-group optical design complements coma aberration for parabolic mirrors and spherical aberration for spherical mirrors excellently.
It achieves a broad 44mm diameter image circle which covers 36mm x 24mm full frame DSLR's and delivers a very sharp image across the entire imaging field.

This amazing corrector has a large 50mm aperture lens to allow securing ample edge-of-field illumination and features the same anti-reflective AS coatings, which are used for Vixen's high-end VSD100F3.8 Astrograph refractor to take advantage of 99% superb high transmission of light across the lens surface.
Ghost and flare images are eliminated substantilly due to the complete matte finish interior.
The eccentricity of each lens is inspected for optical performance of a level higher and high quality control is guaranteed from assembling to shipping.
The Corrector PH is useful at visual observing of extended star clusters and nebulae etc.
