Telescopes, Eyepieces and Astrographs: Design, Analysis and Performance of Modern Astronomical Optics is about every optical element between your eye or your imaging sensor and the night sky. Three expert authors have optimized designs found in today’s astronomy market, explored the origins of different systems, analyzed their optical properties and assessed their performance — and in this book, they present it to you in terms that a non-specialist can understand and put to practical use.
