Early in the 20th century measuring double stars was a popular past time for amateur and professional astronomers. Today only a small group of professionals continue to measure stellar visual binaries. It leaves open an avenue for amateur astronomers to use to update out of date double star catalogs. Listed below are 100 double stars which are within reach of most amateur telescopes. Click on the object to view a map, description and detailed information. The descriptions were made using an 8" Newtonian Dodsonian mounted telescope. A popular sized scope used throughout the amateur astronomy community.
