In these days of computers and CCD cameras visual comet observers can still contribute
scientifically useful data with the help of this handy reference for use in the field. Comets
are one of the principal areas for productive pro-amateur collaboration in astronomy but
finding comets requires a different approach than the observing of more predictable targets.
Principally directed toward amateur astronomers who prefer visual observing or who are
interested in discovering a new comet or visually monitoring the behavior of known comets it
includes all the advice needed to thrive as a comet observer. After presenting a brief overview
of the nature of comets and how we came to the modern understanding of comets this book
details the various types of observations that can usefully be carried out at the eyepiece of a
telescope. Subjects range from how to search for new comets to visually estimating the
brightness of comets and the length and orientation of tails in addition to what to look for
in comet heads and tails. Details are also given of 20 periodic comets predicted to return
between the years 2017 and 2027 that are expected to become suitable targets for visual
observing in addition to information on a famous comet potentially visible each year and
subject to great outbursts of brightness.
