‘… the authors tackle an amazing range of questions. Regardless of how advanced you consider yourself in astronomy … I don’t doubt you will find this trio’s collaborative effort intriguing and highly thought provoking - and that you’ll probably need to reread one or more entries at least twice to digest the full scope of the information presented. I think this work should reside on every astronomy enthusiast’s bookshelf; it will certainly sit on mine.’

‘The fact that the authors are, respectively, an engineer specialising in telescope design, an astrophysicist, and a senior scientist at the Gemini Observatory, ensures that the underlying principles of astronomy are solidly covered, while the contents of the cosmos and … methods of exploring it are not neglected … An excellent bibliography and website list complete a very interesting book that ought to have a place on the shelves of astronomers, whatever their level of acquaintance with the noble science.’
