Omegon ADC atmospheric dispersion corrector

The Omegon ADC Dispersion Corrector helps correct atmospheric refraction of objects, especially when they are close to the horizon. Helps improve sharpness and detail in planetary and lunar photography. Made of BK7 glass, 99% light transmission.

The dispersion corrector produces a dispersion in the opposite direction to the atmosphere and with the right adjustment helps to compensate for it. The amount of repair is adjusted with two pins. In parallel, no correction occurs, in the 180 degree position relative to each other, the correction is maximum.
