ZWO Atmospheric Dispersion Corrector (ADC) - 1.25" Dew Heaters Specs: Special objective filter forWhat is an atmospheric dispersion corrector: An ADC corrector is a small unit that corrects the refraction of light in the atmosphere. For example, a large object like Jupiter has a red and blue color fringe and also appears distorted. This effect is caused by the refraction of light in the Earths atmosphere which acts like a prism. This effect becomes more prominent, depending on how high the object is above the horizon. The deeper the object is, the
