Comets have inspired wonder, excitement and even fear ever since they
were first observed. But they are important members of the solar system,
that contain material from early in the life of the system, held in
deep-freeze. This makes them key in our understanding of the formation
and evolution of many Solar System bodies.
Recent ground- and space-based observations have changed much in our
understanding of comets. Comets, and How to Observe Them gives a summary
of our current knowledge and describes how amateur astronomers can
contribute to the body of scientific knowledge of comets. This book
contains many practical examples of how to construct comet light-curves,
measure how fast a comet's coma expands, and determine the rotation
period of the nucleus. All these examples are illustrated with drawings
and photographs.
Because of their unpredictable nature comets are always interesting and
sometime spectacular objects to observe and image. The second part of
the book therefore takes the reader through the key observing techniques
that can be used with commercially available modern observing equipment,
from basic observations to more scientific measurements.
