How to Observe the Sun Safely 2nd 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 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.
