The Sun is the closest star to Earth, and the only one we can observe in any sort of detail. As such it is a fascinating field of study. It also has the practical advantage, unlike every other astronomical object, of being visible in the daytime! After an introduction to the Sun as a star, the book concentrates entirely on practical aspects for amateur observers: the equipment needed, how to set it up, how to record observations, and how to image the Sun with conventional or digital cameras.
