How to Observe the Sun Safely, Second Edition gives all the basic information and advice the amateur astronomer needs to get started in observing our own ever-fascinating star. Unlike many other astronomical objects, you do not need a large telescope or expensive equipment to observe the Sun. And it is possible to take excellent pictures of the Sun with today's low-cost digital cameras!
This book surveys what is visible on the Sun and then describes 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, this is a great time to get involved with solar observing.
Still emphasizing safety first, this Second Edition reflects recent and exciting advances in solar observing equipment. Chapters 6 through 8 have been completely revised to allow amateur astronomers to compare observing the Sun using digital vs. film cameras and all the latest advances in image processing. Finally, this new edition also includes more than twice as many illustrations as the first, almost half of them new images.

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.

From the book reviews:
“In Macdonald’s book the reader finds different methods and a variety of equipment that can be used for observing our nearest star without any damage to their eyesight and also gets ideas on what to do with the observations. … I found the book very useful … . If you’re thinking of starting to observe the Sun, this is a great book to get more information about all the available options.” (Kadri Tinn, AstroMadness.com, September, 2014)()
