This biography covers the life of Lewis Swift (1820-1913), who discovered 13 comets and nearly 1,200 other deep sky objects.

The sixth and final volume of Cometography provides complete details of every comet seen in the years between 1983 and 1993, featuring their brightnesses, physical descriptions, and orbits. This completes the definitive reference on comets for amateur and professional astronomers, and historians of science.

The book also includes breakthroughs in the study of meteor showers, such as accurate predictions of outbursts as well as comet and meteor observations from the 6th century to the 17th century that were not published in the first edition.

Cometography is a multi-volume catalogue of every comet observed throughout history. The fifth volume provides a complete discussion of each comet seen from 1960 to 1982. This is the definitive reference on comets for amateur and professional astronomers, and historians of science.

Cometography is a multi-volume catalog of every comet observed throughout history. It uses the most reliable orbits known to determine the distances from the Earth and Sun at the time a comet was discovered and last observed, as well as the largest and smallest angular distance to the Sun, most northerly and southerly declination, closest distance to the Earth, and other details to enable the reader to understand the physical appearance of each well-observed comet. Volume 4 provides a complete discussion of each comet seen from 1933 to 1959. It includes physical descriptions made throughout each comet's apparition. The comets are listed in chronological order, and each listing includes complete references to publications relating to the comet. This book is the most complete and comprehensive collection of comet data available, and provides amateur and professional astronomers, and historians of science, with a definitive reference on comets through the ages.

Cometography is a multi-volume catalog of every comet observed throughout history. This latest volume provides a complete discussion of every comet seen during the first part of the twentieth century. This is the definitive reference on comets through the ages for amateur and professional astronomers, and historians of science.

The first in a set of four volumes that make up the most complete and comprehensive catalog of every comet observed throughout history.

Cometography is a four-volume catalog of every comet observed throughout history. This volume provides a complete discussion of every comet seen during the nineteenth century, including details of discovery, closest approaches to the Sun and Earth, paths across the sky, physical descriptions, orbital information, and final observations.
