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.
