Primary objective of this lecture is to present on Charge-coupled Device Astronomy. A charge-coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for example conversion into a digital value. A CCD image is made up of tiny square-shaped pixels. Sampling refers to how many pixels are used to produce detail. Each pixel has a brightness value that is assigned a shade of gray color depending on how many photons strike the pixel during an exposure.
