As probably the only book of its type, this work is aimed at the observer who wants to spend time with something less conventional than the usual fare. Because we usually see objects in space by means of illumination of one kind or another, it has become routine to see them only in these terms. However, part of almost everything that we see is the defining dimension of dark shading, or even the complete obscuration of entire regions in space. Thus this book is focused on everything dark in space: those dark voids in the stellar fabric that mystified astronomers of old; the dark lanes reported in many star clusters; the magical dust belts or dusty regions that have given so many galaxies their identities; the great swirling 'folds' that we associate with bright nebulae; the small dark feature detectable even in some planetary nebulae; and more.
Many observers pay scant attention to dark objects and details. Perhaps they are insufficiently aware of them or of the viewing potential they hold, but also it may be because of the various viewing challenges that dark objects pose. Discussions on viewing methods and the best equipment for a wide cross section of these objects are included, along with many detailed descriptions. The book contains virtually every dark object worth the observer's attention.
Whether viewing live through the eyepiece or indirectly through CCD or other imaging techniques, this unique compendium and discussion of all things dark in space will hopefully prove compelling and rewarding.
As an observer always looking for ways to improve his experience at the eyepiece, Cooke has constructed many telescopes over the years. Increasing apertures were always the hallmark of his often-quirky designs. Finding that the 18-inch aperture of his present telescope was still insufficient to deliver the kind of performance he had in mind, he experimented with newer technologies to bring these elusive goals ever closer. Successful viewing of dark objects requires great contrast. In this respect, some of the newer equipment has proven to be invaluable, enabling dramatic viewing of many dark objects and features in real time and without the need of CCD imaging.
As an author of astronomy books, Cooke also has written Visual Astronomy in the Suburbs (Springer, 2003), Visual Astronomy under Dark Skies (Springer, 2005), and Make Time for the Stars (Springer, 2009). With Dark Nebulae, Dark Lanes and Dust Belts, his astronomical writings continue.

“In Dark Nebulae, Dark Lanes, and Dust Belts, Cooke describes a neglected area in the deep-sky observers’ canon, the dark nebulae, and in addition he includes almost anything that may be perceived as dark in relation to deep-sky objects. … The most likely beneficiaries of this book may well be the keen and more-advanced visual deep-sky observer who loves to chase features such as dark ‘lanes’ in globular star clusters and the dusty areas of spiral galaxies … .” (Nick Hewitt, The Observatory, Vol. 132 (1231), December, 2012)
“It is clear that Cooke … has a passion for visually observing many dark areas of the universe. He clearly articulates this passion in his book and provides a wealth of observing challenges for observers with large amateur instruments. … this reviewer, considers the scope of the book unique, so it would not have any competition in the campus library. Most of the black-and-white figures support the text. … Overall, a useful resource. Summing Up: Recommended. General audiences and lower-and upper-division undergraduates.” (J. R. Kraus, Choice, Vol. 50 (1), September, 2012)
