Paperback. Condición: New. Print on Demand. This book offers guidance on measuring time and celestial coordinates with portable instruments for practical astronomy. With a focus on field work, the author transitions from theoretical principles into practical applications, utilizing a simple and precise numerical approach in each step. The work begins with a review of spherical trigonometry and logarithmic computations. It then introduces the three primary time systems: sidereal, true solar, and mean solar time. Each is considered in-depth, along with the conversion between them. This discussion is followed by corrections applied to celestial coordinates, such as dip of the horizon, refraction, parallax, and diurnal aberration. The author leads the reader from meridian altitudes for latitude and time determinations to orientation by Polaris. The second half of the book is dedicated to instruments and accurate determinations with theodolite, zenith-telescopes, and transit instrument. Time determination with reversal on each star and an azimuth of a terrestrial mark are examined in depth. The author has carefully crafted this book to meet the needs of students, engineers, and practicing astronomers, aiming to equip them with the skills and knowledge necessary to effectively measure time and celestial coordinates in the field. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
