Atmospheric Dispersion Correctors (ADC & EADC)

Atmospheric Dispersion Correctors (ADC and EADC) give you the ability to enhance the precision of your astronomical observations by compensating for the dispersive effects of Earth’s atmosphere. An ADC usually employs a dual-prism setup to correct chromatic dispersion, which causes slight color shifts of celestial objects when viewed near the horizon.

This system allows the dispersive power to be smoothly adjusted across a wide range, providing sharper images and more accurate color rendition. EADCs (Enhanced Atmospheric Dispersion Correctors) deliver higher performance, offering more precise correction suitable for high-resolution instruments and astrophotography.

These correctors are ideal for astronomers who want to observe planets or bright stars with maximum detail while minimizing unwanted atmospheric effects. They can be used with various telescope types, including Schmidt-Cassegrain and refractors, and are particularly useful for low-altitude observations near the horizon.

Choosing an ADC or EADC from Astronomy Plus allows you to optimize your observing sessions and get the most out of your equipment by improving image clarity, color fidelity, and visual comfort during your observations.
