Abstract
Computers are used in the control of telescopes and instruments, for acquisition of digital data from electronic detectors, for image display, analysis, numerical simulations, and more. In this chapter we present some important terminology and explain the standard astronomical data file format known as FITS. Astronomical software is a vast subject beyond the scope of a single chapter. Our goal here is to introduce some well-known software packages but focus more on basic concepts including image visualization, high-pass and low-pass filtering, false color and image restoration by deconvolution.
