The new Astronomers' Universe Series is aimed at the same readership as
the Practical Astronomy Series - active amateur astronomers. This book
provides an up-to-date account of active galaxies which are a major
field of current astronomical research - up to a fifth of all research
astronomers are working on active galaxies. Lists of such objects and
their visual and imaged appearance in commercially available telescopes
are an important component of this book. This is the first coherent and
complete source of information for non-technical readers on an area of
astronomy that fascinates many people. It makes sense of the chaotic and
apparently innumerable types of violently active galaxies. It also
provides the data and teaches the skills needed for users of small
telescopes to observe and image some of these "galaxies in turmoil" for
themselves.
