This book will both arouse your curiosity and answer your questions. Why are there so many different kinds of telescopes? What does each type have to offer? What makes one telescope better than another? Which are best? Why? What are the tradeoffs? As a telescope buyer, you will be better informed; as a telescope maker, you will be able to design custom optics. Many readers will find the analyses of existing designs the most valuable part of the book. Newtonians, Cassegrains, Maksutovs, Schmidt cameras and more are described and analyzed so that you can easily compare them. What's your dream telescope? This book will help you choose it. No longer must you, as an amateur astronomer, meekly accept someone else's opinion about a telescope design. You can scrutinize existing designs and improve them to meet your own standards. Is that new astrographic camera all it's cracked up to be? By raytracing it, you'll know the answer. Here is what three reviewers had to say about this book.
