How to Observe the Sun Safely

The Sun is one of the most accessible and rewarding objects for amateur astronomers to observe, and excellent solar observations are possible without a large telescope or expensive equipment. How to Observe the Sun Safely provides practical guidance for getting started and making the most of commercially available solar-observing equipment, with safety at the forefront throughout.

The book introduces the features and activity that can be observed on the Sun and explains how to record observations and monitor solar activity. It also covers more advanced techniques, including the use of H-alpha and Calcium-K filters for studying prominences and other features of the solar chromosphere, as well as methods for photographing the Sun with both traditional film and modern digital cameras.

This second edition has been updated to reflect developments in solar-observing equipment and includes revised photography chapters, an updated selection of illustrations, and guidance on constructing a simple solar projection box. A useful reference for both newcomers and experienced amateur astronomers interested in safely exploring our nearest star.
