As people who have inmmense and continuing experience in this field, their book may be taken to be authoritative, inclusive, and very much up-to-date— The serious amateur or undergraduate astronomy student will find the careful reading of this new edition an enriching experience.» -Journal of the Royal Astronomical Society of Canada
