What does "CCD Camera" mean?

Table of Contents

A CCD camera, or Charge-Coupled Device camera, is a type of digital camera used in astronomy and other fields to capture images. It works by converting light into electronic signals, allowing for high-quality pictures of stars and other celestial objects.

These cameras are commonly used with telescopes. When light from a star or galaxy hits the CCD sensor, it creates a pattern of electrical charges that represent the image. The camera then processes these charges into a digital image that can be viewed and analyzed.

CCD cameras are important tools in astronomy because they can gather more light than traditional cameras. This means they can capture faint objects that are hard to see with the naked eye. They help astronomers make discoveries and study the universe in greater detail.
