1. What ADC stands for?
ADC is a simplified name of Atmospheric Dispersion Corrector. So the next question is: what is atmospheric dispersion? Basically, The atmospheric dispersion will affect the capturing of high-quality planetary images. Visible light will be refracted when it passes through the atmosphere. Because the refractive index of light of different wavelengths is different, the atmosphere will decompose white light into spectra of different colors like a prism. The lower the angle of the planet, the more obvious the dispersion effect. Just imagine the cover of The Dark Side of the Moon by the great Pink Floyd.
2. Okay, but what is an ADC exactly?
ADC is used to offset the atmospheric dispersion during planetary shooting and visual observation. ADC is composed of a pair of ultra-thin prisms. They can introduce the opposite dispersion that is formed when light passes through the atmosphere to offset the atmospheric dispersion, making the picture sharper. This compact device is designed to reduce color changes caused by atmospheric dispersion and improve the quality of planetary image especially low-altitude planets.
3. How to use it?
Normally, the ADC is placed in between the Barlow lens and the camera. It’s very simple to use an ADC. Just set the ADC level first, and then move two levers by the same amount to control the prism until there is no chromatic aberration at the edge of the planet.
Svbony’s ADC is about to be released. Right now It’s in test processing and we want to introduce this new product to you when it’s finally truly ready and we are very excited about it. Please keep following us for any updates!
