CCD photometry

Part of the Springer Praxis Books book series (PRAXIS)


CCD imagers have revolutionized amateur astrophotography. They have also given amateur astronomers the ability to conduct a variety of projects that entail the accurate measurement of the brightness of celestial objects. That is the essence of the science of photometry: accurate characterization of the quantity of light that is coming from an object. In this introductory section, I’ll cover the barest summary of what you’ll want to know about light, the atmosphere, and the CCD. Photometry is a broad subject, and one where amateur astronomers are actively collaborating with professionals on a wide variety of projects. It is also one of those subjects where “the more you know, the more you realize you need to learn.” The references at the end of this chapter are well worth reading (and owning for reference) as your knowledge and skill increases and you discover yet more things that you don’t know.
