The purpose of this book is to introduce the reader to the numerous safe methods of observing the Sun and solar eclipses, and to suggest objects and features to observe and observing programmes to follow. So much energy comes from the Sun that by failing to observe safe working practices it is possible to damage your eyes or equipment. The care that is needed is emphasised throughout the book. Always make sure that you have read the whole of a section or chapter before starting any observational work. However in warning when care is needed in observing, there is a danger of scaring people off observing the Sun altogether. Let me emphasise therefore that observing the Sun can be done in complete safely, providing that the precautions discussed in the book are followed. The Sun then provides one of the most interesting objects in the sky for an astronomer to study at all times, and during a total solar eclipse becomes uniquely fascinat- ing to both astronomers and the general public alike. So take heed of the warnings given here but do not let them stop you trying out the safe observing methods. I wish you clear sunny skies and many hours of fun.
