Ce livre est la transition parfaite entre la saga Harry Potter et la trilogie des Magiciens. [...] En plus de tout ça, on trouve, en vrac : des références culturelles géniales, l'utilisation de la technologie par les sorciers, une guerre inter-espèces, la lutte contre le sexisme, des super-héros discrets, quelques insultes bien envoyées [...] un roman one-shot à lire absolument pour tous ceux qui aiment la magie, les histoires de grands ados (les héros sont majeurs) et, ok, les histoires d'amour un peu.
With the advent of inexpensive, high-power telescopes priced at under $250, amateur astronomy is now within the reach of anyone, and this is the ideal book to get you started. The Illustrated Guide to Astronomical Wondersoffers you a guide to the equipment you need, and shows you how and where to find hundreds of spectacular objects in the deep sky -- double and multiple stars as well as spectacular star clusters, nebulae, and galaxies.
You get a solid grounding in the fundamental concepts and terminology of astronomy, and specific advice about choosing, buying, using, and maintaining the equipment required for observing. The Illustrated Guide to Astronomical Wondersis designed to be used in the field under the special red-colored lighting used by astronomers, and includes recommended observing targets for beginners and intermediate observers alike. You get detailed start charts and specific information about the best celestial objects.
The objects in this book were chosen to help you meet the requirements for several lists of objects compiled by The Astronomical League(http://www.rasc.ca) (Lien -> http://www.rasc.ca): Messier Club.
- Binocular Messier Club
- Urban Observing Club
- Deep Sky Binocular Club
- Double Star Club
- RASC Finest NGC ListCompleting the list for a particular observing club entitles anyone who is a member of the Astronomical League or RASC to an award, which includes a certificate and, in some cases, a lapel pin.
This book is perfect for amateur astronomers, students, teachers, or anyone who is ready to dive into this rewarding hobby. Who knows? You might even find a new object, like amateur astronomer Jay McNeil. On a clear cold night in January 2004, he spotted a previously undiscovered celestial object near Orion, now called McNeil's Nebula. Discover what awaits you in the night sky with theIllustrated Guide to Astronomical Wonders.
Robert Bruce Thompson is a coauthor of O'Reilly's Building the Perfect PC and PC Hardware in a Nutshell. A born geek, he built his first computer in 1976 with 256 bytes of memory, toggle switches, and no operating system. Since then, he has bought, built, upgraded, and repaired hundreds of PCs for himself, employers, customers, friends, and clients. Robert spends most clear, moonless nights outdoors with his 10-inch Dobsonian reflector telescope, hunting down faint fuzzies, and is currently designing a larger truss-tube Dobsonian (computerized, of course) that he plans to build.
