Figure 6-19: R I V U X G
Charge-Coupled Devices (CCDs) (a) These CCDs are part of the Pan-STARRS detector developed at MIT's Lincoln Laboratory. The highlighted square contains 23 million pixels from 64 individual CCDs. The full detector is made from 60 of the 5 cm wide squares, has about 1.4 billion pixels, and is nearly 40 cm wide. (b) This negative print (black stars and white sky) shows a portion of the sky as imaged with a 4-meter telescope and photographic film. (c) This negative image of the same region of the sky was made with the same telescope, but with the photographic film replaced by a CCD. Many more stars and galaxies are visible.
