Modern amateur astronomical telescopes are both powerful and affordable. Spectroscopy - in which the light a star is broken down into a rainbow-coloured spectrum - is becoming more and more popular as instruments and techniques improve with technology. Spectroscopy can tell us a great deal about a star - not the least what it is made of, and how fast it is travelling away from us. Practical Amateur Spectroscopy contains everything an amateur astronomer needs to know to begin observing, but goes relatively deeply into the subject for those who are already involved.
