Ideal for colour planetary work, the ADC will correct the RGB alignment dispersion during acquisition that is caused by the atmosphere. This gives you a sharper capture with more surface detail. See the website for before/after pictures and detailed description of the advantages. (Shooting planets lower on the horizon for example).
