Originally published in 1930, this series of charts by acclaimed astronomer Eugene Delporte fixes the boundaries of the constellations in the Northern and Southern hemispheres according to the lines of ascension and declination at the astronomical epoch B1875.0. The limits of each constellation are determined so as to maintain the boundaries at the time of their definition, with all post-1925.0 variables indexed to take new limits into account. This book will be of value to anyone with an interest in astronomy.
