The ZWO Atmospheric Dispersion Corrector is used to reduce the effect of atmospheric dispersion on lunar and planetary images. By aligning two prisms made of H-K9L (BK7 equivalent) glass, you are able to significantly compensate for the optical distortions and aberrations that come with viewing the planets at lower elevations.

The ADC works best when paired with an optical system slower than f/10, such as a Schmidt-Cassegrain. For other setups, the use of a Barlow lens is recommended.

Outstanding innovative product. Fits my observing view area near the horizon perfectly and clears up images as advertised. Especially useful for planetary - Mars, Venus, Mercury. Will test it with the Moon. Well constructed and highly recommended. Be aware of back focus and fully compensate it as needed. Waiting for clear skies to test it on a C9.25" and C14 by taking images. It's another good tool to have in the arsenal for clearing up astronomical images.
