ZWO 1.25" ADC Atmospheric Dispersion Corrector - ADC type-binocular-viewers-and-accessories Multi-coated optics dramatically increase lightThe ZWO Atmospheric Dispersion Corrector is used to reduce the effect of atmospheric dispersion on lunar and planetary images. This device dramatically reduces the prismatic smearing caused by the passage of the light through our atmosphere and allows planetary images to be taken which show noticeably finer detail. Commercial ADCs are relatively new. Their significant benefits, however, justify more astronomers knowing about them. As well as being an
