Introduction

 Spectroscopy is a key tool for the professional trying to understand the mechanisms which cause variability in stars. Amateur spectroscopists are rather thin on the ground however as it is generally seen as too difficult, expensive or both.
In practise however, anyone who is currently digital astro-imaging or doing photometry with a CCD camera  can get into simple (but still scientifically interesting) spectroscopy without breaking the bank. Additionally an increasing number of amateurs are tackling the challenges of high resolution spectroscopy. So much so that the AAVSO are planning to develop a database for amateur spectra of variable stars.

Content 
In this workshop presentation I will:

1.Describe the equipment I use to take low and high resolution spectra.
2.Give some examples of  variable star phenomena which can be measured spectroscopically.
3.Walk through the procedure to turn a spectrum image into useful scientific data.
4.Give some sources of further information
