This is a great book full of pictures and a ton of information. However, there is so much info that it overwhelmed my son. It is layed out with several tidbits of info spread all over the pages. Although interesting, it was too complicated for children. Would recommend this book for kids over 13. Definately worth getting if you want an introduction to using telescopes and space but it should be for the older teens and adults. I do plan on keeping this book as I think it will provide a lot of good information when he is older. Until then it will be on the shelf waiting to be rediscovered!
