This combined set is comprised of the Spectral Atlas for Amateur Astronomers, a full colour reference featuring detailed commented spectral profiles of more than one hundred astronomical objects, and its companion guide, Spectroscopy for Amateur Astronomers, which explains in detail the methods for recording, processing, analysing and interpreting spectra. Together they cover astronomical objects such as stars, planets, nebulae, novae, supernovae; stellar clusters, galaxies and quasars; astronomical events such as eclipses and comet passages; and some terrestrial light sources. This comprehensive reference set benefits many groups, from individual novices and learners in astronomy clubs to advanced students and teachers of astrophysics. It aims to help readers understand and practise this scientifically important and growing field of amateur astronomy, and to encourage future professional-amateur collaborations.

Featuring detailed commented spectral profiles of more than one hundred astronomical objects, in colour, this spectral guide documents most of the important and spectroscopically observable objects accessible using typical amateur equipment. It allows you to read and interpret the recorded spectra of the main stellar classes, as well as most of the steps from protostars through to the final stages of stellar evolution as planetary nebulae, white dwarfs or the different types of supernovae. It also presents integrated spectra of stellar clusters, galaxies and quasars, and the reference spectra of some terrestrial light sources, for calibration purposes. Whether used as the principal reference for comparing with your recorded spectra or for inspiring independent observing projects, this atlas provides a breathtaking view into our Universe's past. The atlas is accompanied and supplemented by Spectroscopy for Amateur Astronomers, which explains in detail the methods for recording, processi
