This book provides a detailed biographical account of the industrious late nineteenth-century astronomer William Frederick Denning who, in later life, rose to be a celebrated public figure and a highly respected amateur astronomer. The book also examines Denning’s many contributions to the astronomy of his time. As an indomitable promotor of amateur astronomy, Denning was closely involved in the formation of the short-lived, but historically pivotal, Observational Astronomy Society (OAS) in 1869. Readers will learn about the origins and the observational programs initiated by the OAS, and the author also presents a series of biographical sketches of its most industrious members. Furthermore, by examining Denning’s letters and publications, the author shows how he helped to nurture the growth of amateur astronomy, also teaching amateur observers how to make their efforts scientifically useful. A stalwart observer and enthusiast himself, Denning was a key player in the development of meteor astronomy in England, culminating in his being invited, in 1922, to be the first President of Commission 22 (meteors, meteorites and interplanetary dust) of the newly formed International Astronomical Union. The text follows the development and rapid growth of meteor astronomy during the nineteenth century, focusing upon the key observations and important theoretical advances. In addition, it pays tribute to pioneering practitioners, who, along with Denning, set out to unravel the story and secrets of the shooting stars. While not an openly forthright or strident figure, Denning, at the height of his career, became embroiled in two public and controversial issues. The first related to his pseudo-scientific theory of optical blurring, and his belief that large-aperture telescopes performed less efficiently than smaller-aperture telescopes when used in the study of planetary disks. The second concerned the mysterious issue of stationary meteor shower radiants—an apparent observational reduction that was completely at odds with both the standard theories of gravitational dynamics and the generally accepted notion of meteoroid stream structure. The book explores these two controversies and uses them to examine Denning’s outlook on scientific methodology.

This is an informative, up-to-date and well-illustrated guide to planetary observations for amateurs. After a brief description of the solar system and a chapter on the celestial sphere, readers are shown how to choose, test and use a telescope with various accessories and how to make observations and record results. For each planet and the asteroids, details are given of observational techniques, together with suggestions for how to make contributions of scientific value. From a general description and detailed observational history of each planet, observers can anticipate what they should see and assess their own observations. The chapter on planetary photography includes the revolutionary use of videography, charge coupled devices and video-assisted drawing. There are also chapters on making maps and planispheres and on photoelectric photometry.

"A review of astronomy" (varies).

An inspiration to amateur and professional astronomers alike, the Yearbook of Astronomy warrants a place on the bookshelf of all sky watchers and stargazers. Maintaining its appealing style and presentation, the Yearbook of Astronomy 2019 contains an authoritative set of sky charts and comprehensive jargon-free monthly sky notes to enable backyard astronomers everywhere to plan their viewing of the years eclipses, comets, meteor showers and deep sky objects.In addition, a variety of entertaining and informative articles present the reader with information on a wide range of topics including, among others, The Cassini-Huygens Mission to the Saturn System; 100 Years of the International Astronomical Union; The First Micro-Quasar; Getting the Measure of Double Stars; Asaph Hall: Man of Mars; and Science Fiction and the Future of Astronomy.The Yearbook of Astronomy has been around for well over half a century and, as it heads towards its Diamond Jubilee edition in 2022, continues to be essential reading for anyone lured by the magic of astronomy and who wants to extend their knowledge of the Universe and the wonders it plays host to.
