This book is specifically for stargazers living in the glare of urban sprawls, where all but the brightest stars are lost to light pollution. ÊDiscovering Double Stars II is thoroughly revised and updated, extending coverage from 300 double stars in the first edition to 950 in this latest edition.
The level of data on each double star system has been greatly extended and the usability of the book has been enhanced, with far less page-flipping in the dark and easy star-hopping with your finder scope to each double. All doubles in this book are accessible by moderately-sized telescopes.
The book also contains hundreds of deep sky objects, several charts of selected star clusters and their doubles, and a section on light pollution with sky darkness estimation charts. All charts are in full color, indicating the spectral class of each star, with doubles color coded for quality and brightness.
Cross-references to the SAO, HIP and Gaia DR2 catalogs are provided for the doubles.
