The present work is not designed for professional students of astronomy, but for another and larger class found in technical colleges. For many years it has been the authors duty to teach to students of engineering the elements of practical astronomy, and the experience thus acquired has gradually produced the unconventional views that find expression in the present text and which, to the authors mind, are justified by the following considerations: In the engineering curriculum, work in astronomy is a part of a course of technical and professional training of students who have no purpose to become astronomers. Under these circumstances it seems the duty of the instructor to select for presentation those parts of astronomical practice most closely related to the work of the future engineer and, with reference to the narrow limits of time allotted the subject, to keep in the background many collateral matters that are of primary interest and importance to the student of astronomy as a science.

Paperback. Etat : 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.
