The numerical work is really quite simple and basic, and should frighten nobody who has a genuine wish to learn a little more than might be gleaned from one of the many coffee-table books covering similar ground...This is a useful book for students, and would also suit the teacher who may touch on astronomical topics during a science course. The style and content will allow the text to be revised in years to come as new discoveries and theories prove to make this necessary, and at a cost that is very appropriate for the target market. --Gnomon, Newsletter of the Association for Astronomy Education
