Produktbeschreibung

Amateur astronomers interested in learning more about astronomical spectroscopy now have the guide they need. It provides detailed information about how to get started inexpensively with low-resolution spectroscopy, and then how to move on to more advanced  high-resolution spectroscopy. Uniquely, the instructions concentrate very much on the practical aspects of using commercially-available spectroscopes, rather than simply explaining how spectroscopes work. The book includes a clear explanation of the laboratory theory behind astronomical spectroscopes, and goes on to extensively cover the practical application of astronomical spectroscopy in detail. Two popular and reasonably-priced commercially available spectrographs are used as examples. The first is a low-resolution (100 line/mm) transmission diffraction grating, the Star Analyser spectrograph. The second spectrograph considered is at the other end of the market, the high-resolution Lhires III with both 2400 and 600 line/mm reflection diffraction gratings. While considerably more expensive, this is a popular and excellent scientific instrument, that allows more advanced amateur astronomers to produce scientifically valuable data. With all of these tools in place, the amateur astronomer is well-prepared to forger deeper into the night sky using spectroscopy.
