Paperback. Condizione: New. Print on Demand. This book presents a collection of methods for solving problems in spherical and practical astronomy. It begins by establishing a simple and accurate expression for atmospheric refraction, then continues by exploring practical methods for tasks such as correcting the sun's declination for atmospheric effects, determining the value of a single level division on a spirit level, and simultaneously determining the exure, inequality of pivots, and the value of a level division for a broken transit. The author has made a point to incorporate methods that are adaptable to field use and require minimal auxiliary apparatus. The final topic covered is the determination of latitude and time from equal altitudes of stars. Combining a pair of stars, a Southern star and a polar star, the author provides formulae for calculating latitude and atmospheric conditions, a problem typically solved in the past by involving three stars and complex computations. The book concludes with a simple and rigorous equation for combining observations to obtain accurate calculations in the field.
