Code: 37246
Optimised field flattener for Vixen Super ED 81mm, 103mm and 115mm SD series apochromat refractors


Covering entire imaging-field of DSLR with full-format, the kit consists of the high performance flattener lens and connecting rings designed for the superb SD81S, SD103S, and SD115S optical tubes.

The SD flattener HD improves the flat-field performance toward the edge of field of view closely maintaining the original focal length of the SD-series optical tubes, fully covering the imaging field of DSLR camera with full-format sensor at image circle of 44mm diameter.

Extraordinary High Contrast

The same anti-reflective AS coatings, which are used for our high-end VSD100F3.8 Astrograph,
are used to take advantage of 99.9% superb high transmission of light per lens surface. Loss of
light, ghost and flare images are eliminated substantilly due to the complete matte finish inside.

Ultra sharp image over entire imaging field on DSLR full-format sensor when used in combination with the optional Reducer HD. With this combination the focal length is reduced by 0.79x (F7.7?6.1). While maintaining image circle largely improving sharpness over the entire imaging field.
