We decided to buy a telescope, and the advice we found on makes/types etc... in this book was invaluable. Unlike a lot of magazines and other books they cover a whole host of manufacturers - not just USA. It gives advice, comparisons, good+bad features between telescopes, eyeieces, filters and everything related to astronomy. As well as the information in the chapters on each element of astonomy, there are appendices for different price ranges and manufacturers, together with basic information on each. I'd recommend it as an essential purchase for anyone starting out in astronomy.
