内容説明 This Atlas provides a complete set of images of Local Group Galaxies (excluding the three for which identification atlases are already in print) and shows the most important objects， including many thousands of individual stars and interstellar objects. It is unique in its coverage and format and provides a source of these fundamental data that will be used for many years. Researchers， students and even amateur astronomers will be able to use the Atlas to identify and study the various components of the nearly 30 important galaxies covered by the Atlas. The objects identified on the more than 200 charts include variable stars， globular star clusters， open star clusters， stellar associations， emission regions， supernova remnants， planetary nebulae and dust clouds. Each galaxy is accompanied by an extensive bibliography.
