This title concentrates on providing practical, on-the-spot advice to the amateur astronomer who is interested in observing the Sun, using commercially available equipment. This book surveys what is visible on the Sun, before describing how to record solar features and measure solar activity levels. There is also an account of how to use H-alpha and Calcium-K filters to observe and record prominences and other features of the solar chromosphere, the Sun's inner atmosphere. Because we are just entering a period of high activity on the Sun, following a long, quiet period, many more amateur astronomers will become interested in observing it.
The second edition includes an update of Chapter 2 to reflect advances in solar observing equipment since 2002, and a section on building a solar projection box, originally included in the main body of this chapter has been moved to Appendix A. Also Chapter 6 thru 8 have been completely revised to give amateur astronomers advice on how to use film to photograph the Sun, and how to use digital cameras. This new edition also includes more than twice as many illustrations as the first and almost half of them new images.
