The interstellarum Deep Sky Guide is an innovative illustrated guide to accompany the well-received interstellarum Deep Sky Atlas. Taking an intuitive visual approach, for each spread of the Atlas, the Guide focuses on carefully selected objects, either as colored composite POSS plates or through the authors' own eyepiece sketches.

Throughout the ages, comets, enigmatic and beautiful wandering objects that appear for weeks or months, have alternately fascinated and terrified humankind. The result of five years of careful research, Atlas of Great Comets is a generously illustrated reference on thirty of the greatest comets that have been witnessed and documented since the Middle Ages. Special attention is given to the cultural and scientific impact of each appearance, supported by a wealth of images, from woodcuts, engravings, historical paintings and artifacts, to a showcase of the best astronomical photos and images. Following the introduction, giving the broad historical context and a modern scientific interpretation, the Great Comets feature in chronological order. For each, there is a contemporary description of its appearance along with its scientific, cultural and historical significance. Whether you are an armchair astronomer or a seasoned comet-chaser, this spectacular reference deserves a place on your shelf.

This revolutionary deep sky atlas, designed with the practical observer in mind, shows all deep sky objects according to their actual telescopic visibility, in 4-, 8- and 12-inch telescopes. Spiral-bound and printed in color on dew-resistant paper, this innovative atlas is the ideal companion for amateur observers of all levels.
