Deep-Space CCD Cameras are capable of outstanding astrophotography image quality! Unlike traditional cameras, the CCD telescope cameras use top-notch imaging technology to maximize pixelation and exposure times. This allows them to be more accurate over long-exposure shots.
CCD cameras use a small, rectangular chip of silicon called a Charge-Coupled Device to gather and record incoming light instead of film. The silicon chip is a solid-state electronic component comprised of light-sensitive cells called photo-sites. Each photo-site is its own pixel. Just one tiny area in a photograph can contain hundreds of thousands of pixels. When incoming light strikes the photo-site, the photoelectric effect creates and builds an electron charge for as long as exposure occurs. The electrons are then "stored" in their individual cells until the analog-to-digital converter unloads the array, counts the electrons, and reassembles them into the "big picture" that is sent to your computer. These traits make them incredible for high-resolution imaging and photography, but also means that you will need to use a computer to process your images. Astronomy Software is available for processing your CCD images and can be provided alongside your camera purchase if you are interested.
