The majority of stars are gravitationally bound systems of two or more stars that are only distinguishable through a telescope. Their orbital periods range from days to millennia, often making double star research a multi-generational endeavor. Thus, astronomers today contribute measurements of systems that have been observed, in many cases, for centuries. Since the fundamentals of double star research are straight-forward and entry equipment is low cost, double star research is open to amateur and student astronomers. This book exposes the reader to a diverse sampling from the Journal of Double Star Observations detailing both historical and modern observations as well as the techniques and technologies used by amateurs, students, and professionals.
