For those looking for a book of initiation compact, simple and comprehensible to tame the sky, this guide is a good tool. It allows you to become familiar with the different constellations, shows ALSO observable with binoculars objects (I tested M42 in Orion binoculars, fabulous!). Printed cards are a fluorescent ink, legible in black with a red lamp. The two hemispheres and their own constellations are represented, so that you were not looking objects or star you will ever see in your latitude! Do not ask for more than that for which it is made: to learn. Personally, I have always at hand. It is not bulky. Of course, the constellations are simplistic, but the general shape is found and there are easy marks for guidance. In summary, a good pair of binoculars, a good sky, a red lamp and this guide are sufficient for a good evening. But if I can give advice, already observe with the naked eye, it is a very good exercise. Enjoy reading.
