The ADC corrects the dispersive effects of Earth´s atmosphere. You will get sharper images of planets and moon.

• The Atmospheric Dispersion Corrector is a revolution in observing and imaging objects.
• Through the use of 2 high quality prisms, it corrects the false colour introduced by the earth´s atmosphere.
• When used for planetary imaging, it changes the clarity of the image dramatically, particularly in the luminence channel when LRGB imaging.
• Adaption is simple through T2 thread on both sides
• You can use the ADC for visual and photography
• You see the result very clear through the eyepiece
