"Observing the Sun" is for amateur astronomers at all three levels:
beginning, intermediate, and advanced.
The beginning observer is often trying to find a niche or define a
specific interest in his hobby, and the content of this book will spark
that interest in solar observing because of the focus on the dynamics of
the Sun.
Intermediate and advanced observers will find the book invaluable in
identifying features (through photos, charts, diagrams) in a logical,
orderly fashion and then guiding the observer to interpret the
observations.
Because the Sun is a dynamic celestial body in constant flux,
astronomers rarely know for certain what awaits them at the eyepiece.
All features of the Sun are transient and sometimes rather fleeting.
Given the number of features and the complex life cycles of some, it can
be a challenging hobby. "Observing the Sun" provides essential
illustrations, charts, and diagrams that depict the forms and life
cycles of the numerous features visible on the Sun.
