Features: 1. The ADC corrects the dispersive effects of earth´s atmosphere. You will get sharper images of planets and moon. 2. The Atmospheric Dispersion Corrector is a revolution in observing and imaging objects. 3. Through the use of 2 high quality 1/4λ BK7 prisms, it corrects the false colour introduced by the earth´s atmosphere. 4. When used for planetary imaging, it changes the clarity of the image dramatically, particularly in the luminance channel when LRGB imaging. 5. Adaption is simple through T2 thread & 1.25" barrel on camera side and 1.25" barrel on telescope side.
