About This Book

A chronological survey examines observational astronomy from ancient naked-eye methods through the invention and refinement of optical instruments. It explains the principles of refraction and reflection, refracting and reflecting telescopes, eyepieces, and the manufacture of lenses and specula, and addresses mounting, adjustment, and clockwork for precise measurement. The text then describes meridian and equatorial practices, transit and micrometer techniques, and developments in astronomical physics, including spectrum analysis, the spectroscope and telepolariscope, and the methods and results of celestial photography.
