Pierro Astro ADC atmospheric dispersion corrector

In nice clean condition

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

An Atmosperic Dispersion Corrector or ADC, is a clever little device which corrects the disperse effects of the earth´s atmosphere on light rays. Put simply, when you view a bright object such as a planet with a telescope, you will often see colour fringing. So a large object like Jupiter may have a red and blue fringe in addition to being distorted. This is caused by the effect the earths atmosphere has on the light from the object as it passes through it. The atmosphere is basically acting like a prism. This effect changes depending on how high the object is above the horizon. The lower it is the greater the effect. Because in northern Europe bright objects like planets are never that high, so we suffer from the effect more.

An ADC corrects this dispersion effect, allowing you to see and image objects free of these distortions and aberrations. No more waiting for an object to get high enough in the sky for it to offer an acceptable view. Now you can view it anytime with crystal clear quality.
