The Cambridge Double Star Atlas is back! It is the first and only atlas of physical double
stars that can be viewed with amateur astronomical instruments. Completely rewritten this new
edition explains the latest research into double stars and looks at the equipment techniques
and opportunities that will enable you to discover observe and measure them. The target list
has been completely revised and extended to 2500 binary or multiple systems. Each system is
described with the most recent and accurate data from the authoritative Washington Double Star
Catalog including the HD and SAO numbers that are most useful in our digital age. Hundreds of
remarks explain the attributes of local rapidly changing often measured or known orbital
systems. The color atlas charts by Wil Tirion have been updated to help you easily find and
identify the target systems as well as other deep-sky objects. This is an essential reference
for double star observers.
