Paperback. Condición: New. Print on Demand. This book tabulates the amount of light coming from every 10 degrees of galactic longitude and latitude for stars of all magnitudes from 6 to 18. The author also presents an extrapolated value for the contribution from stars brighter than magnitude 6 and fainter than 18, using a novel extrapolation technique. Additionally, the author provides a table for converting from galactic to equatorial and ecliptic coordinates for the convenience of readers. This book is a valuable tool for astronomers, astrophysicists, and anyone interested in the study of the night sky and the distribution of stars within our galaxy. It builds upon the work of Kapteyn and van Rhijn, and extends the earlier star counts by providing integrated starlight values for each magnitude interval and each galactic coordinate. The book also highlights systematic differences between total integrated starlight based on star counts and recently measured values by Elsasser and Haug, drawing attention to the need for further investigation into this discrepancy. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
