Svbony SV199 1.25" is a specialized corrector that allows to minimize the negative influence of atmospheric dispersion on the detail of images in planetary astrophotography.

The heart of the corrector is a system of two prisms made of BK7 glass with a maximum adjustment range of 4.5°. The prism surfaces are finished with a precision of 1/4 λ and covered with an anti-reflective coating with a wide spectral range from 300 to 700 nm.

To facilitate operation, the corrector is equipped with a clear angular scale and a spirit level.
