Recording, Processing, Analysis and Interpretation

  • Gathers together all the basic knowledge for a quick understanding and an easy reading of the principles of astronomical spectroscopy
  • Presents an overview of measurement and calibration methods, which has been missing up until now, describing a range of detailed analysis options, accessible to averagely equipped amateurs
  • While the physical basics provided should be widely understood by the majority of amateurs, some dedicated sections are directed to advanced students and amateurs with more advanced knowledge of mathematics and quantum mechanics


This accessible guide presents the astrophysical concepts behind astronomical spectroscopy, covering both the theory and the practical elements of recording, processing, analysing and interpreting your spectra. It covers astronomical objects, such as stars, planets, nebulae, novae, supernovae, and events such as eclipses and comet passages.

Suitable for anyone with only a little background knowledge and access to amateur-level equipment, the guide's many illustrations, sketches and figures will help you understand and practise this scientifically important and growing field of amateur astronomy, up to the level of Pro-Am collaborations.

Accessible to non-academics, it benefits many groups from novices and learners in astronomy clubs, to advanced students and teachers of astrophysics. This volume is the perfect companion to the Spectral Atlas for Amateur Astronomers, which provides detailed commented spectral profiles of more than 100 astronomical objects.

Table of Contents:

  • Physical basics of spectroscopy
  • Electron transitions and formation of the spectra
  • Quantum mechanical aspects of spectroscopy
  • Types and function of dispersive elements
  • Types and function of spectrographs
  • Recording of the spectra
  • Processing of recorded spectra
  • Calibration of the spectra
  • Analysis of the spectra
  • Temperature and luminosity
  • Expansion and contraction
  • Rotation and orbital elements
  • Gravity, abundance and magnetic fields
  • Analysis of emission nebulae
  • Amateurs and astronomical science.


The author Marc F. M. Trypsteen is a Belgian pharmacist and astronomer, with a background in analytical chemistry and spectroscopy. He has lectured on astronomical spectroscopy at university, high schools, observatories and astronomy clubs. He is co-founder of the Astro Event Group Belgium and also of the Astropolis Space Science Center in Ostend, where, in addition to outreach activities, he is responsible for the section on spectroscopy education and research.

The author Richard Walker spent his career in civil engineering, planning large projects such as power plants, dams and tunnels. Now retired, in the last ten years he has focused increasingly on stellar astronomy and on the indispensable key to this topic - spectroscopy. He undertook a large observing project to record and document the spectra of the most important astronomical objects, and chose to share this gathered information for the benefit of other amateurs worldwide.
