Paperback. Condición: New. Print on Demand. This book provides a unique view into the science of mapping celestial bodies using photographic plates. Written in 1890, its relevance persists today, remaining one of the earliest demonstrations of how different photographic exposure times and aperture sizes can influence our perception of the night sky's brightness. Through extensive research and experiments, the author presents an empirical equation to calculate a star's magnitude and visual brightness, based on photographic data and taking into account Earth's atmospheric conditions. This groundbreaking work lays the groundwork for modern astronomy and astrophotography, helping us better understand the scale and depth of the cosmos.
