This is a fully comprehensive guide to "choosing and using" the LXD55 / 75 computer-controlled – "go to" – series of telescopes. It is intended both for beginners and more advanced practical amateur astronomers. The LXD series of telescopes is unusual in having German Equatorial Mounts – GEMs – rather than the more common altazimuth design. Although setting up a GEM with a go-to system is more involved than setting up the equivalent altazimuth mount, there are many advantages in the system, including zero field rotation. A User’s Guide to the Meade LXD55 and LXD75 Telescopes contains a wealth of information on setting up, using and maintaining the telescope, along with lots of hints, tips, and tricks for getting the very best out of it. Coverage in advanced techniques for experienced astronomers and LXD users include imaging, interfacing with a PC or laptop, using available accessories, and troubleshooting.

This book—unique in the literature—provides readers with the mathematical background needed to design many of the optical combinations that are used in astronomical telescopes and cameras. The results presented in the work were obtained by using a different approach to third-order aberration theory as well as the extensive use of the software package Mathematica®. The newly presented approach to third-order aberration theory adopted is based on Fermat’s principle and the use of particular optical paths—not rays—termed stigmatic paths, allowing for easy derivation of third-order formulae. This approach enables readers to understand and handle the formulae required to design optical combinations without resorting to the much more complex Hamiltonian formalism and Seidel's relations. Additional features and topics: * Presentation of the third-order design of cameras and telescopes with the aid of Mathematica eliminates the need for tedious computer calculations * Mathematica notebooks accompanying each optical combination analyzed in the book are available for download at http://extra.springer.com/978-0-8176-4871-8 * Discussion and analysis of specific optical devices: Newtonian and Cassegrain telescopes; Schmidt, Wright, Houghton, and Maksutov cameras; and other optical combinations, such as the Klevtsov telescope and the Baker–Schmidt flat-field camera * Additional supplementary material available at the publisher's website * Many worked-out examples and exercises Geometric Optics is an excellent reference for advanced graduate students, researchers, and practitioners in applied mathematics, engineering, astronomy, and astronomical optics. The work may be used as a supplementary textbook for graduate-level courses in astronomical optics, optical design, optical engineering, programming with Mathematica, or geometric optics.

In 1777, the Danish astronomer Thomas Bugge (1740-1815) was appointed professor of mathematics and astronomy at the University of Copenhagen. Keen to modernize the existing observatory on top of the Round Tower, he travelled through Germany to Holland and England to learn more about the state of astronomy and instrument-making in these countries. During his tour he kept a journal in which he noted what he saw, whom he met and which books and instruments he bought. He also included dozens of sketches and drawings, which greatly add to the historical value of his manuscript.The document lay undi
