'The claim of a wealth of information in this book not found anywhere else in popular astronomy is well justified … history, astrophysics and latest research findings of each object - it comes with. If the interest is simply in observing, [then] the non-colour photo, basic data, finder chart and sketch by the author are more than enough to get the readers started … Despite the recommendation that it is to be used together with Deep-Sky Companions: The Messier Objects … this book can actually stand alone … Under a dark sky condition, the objects are all observable with at least a 4-inch telescope, binoculars or even just the naked eye.' B. Ishak, Contemporary Physics
