PDF-(BOOK)-The Amateur Astronomer\'s Introduction to the Celestial Sphere

This introduction to the night sky is for amateur astronomers who desire a deeper understanding of the principles and observations of nakedeye astronomy It covers topics such as terrestrial and astronomical coordinate systems stars and constellations the relative motions of the sky sun moon and earth leading to an understanding of the seasons phases of the moon and eclipses Topics are discussed and compared for observers located in both the northern and southern hemispheres Written in a conversational style only addition and subtraction are needed to understand the basic principles and a more advanced mathematical treatment is available in the appendices Each chapter contains a set of review questions and simple exercises to reinforce the readers understanding of the material The last chapter is a set of selfcontained observation projects to get readers started with making observations about the concepts they have learned William Charles Millar currently Professor of Astronomy at Grand Rapids Community College in Michigan has been teaching the subject for almost twenty years and is very involved with local amateur astronomy groups Millar also belongs to The Planetary Society and the Astronomical Society of the Pacific and has traveled to Europe and South America to observe solar eclipses Millar holds a Masters degree in Physics from Western Michigan University.

Consequently, many amateur astronomers miss out on some of the most fascinating aspects of the subject. Astrophysics Is Easy! cuts through the difficult mathematics and explains the basics of astrophysics in accessible terms. Using nothing more than plain arithmetic and simple examples, the workings of the universe are outlined in a straightforward yet detailed and easy-to-grasp manner. The original edition of the book was written over eight years ago, and in that time, advances in observational astronomy have led to new and significant changes to the theories of astrophysics. The new theories will be reflected in both the new and expanded chapters. A unique aspect of this book is that, for each topic under discussion, an observing list is included so that observers can actually see for themselves the concepts presented -stars of the spectral sequence, nebulae, galaxies, even black holes. The observing list has been revised and brought up-to-date in the Second Edition. If you’ve ever been interested in the night sky and the wonders above our heads, search no further: your ultimate resource for all things in the universe is here. From David Dickinson and Fraser Cain, publisher of the widely popular astronomy news site, Universe Today, comes the complete guide of the night sky, ranging from the best tips and tricks for viewing, an overview of the solar system and our galaxy to exclusive interviews with top NASA scientists, interwoven with exclusive, beautiful photography from top night sky photographers.Foreword is expected to be written by a top industry professional (hopefully Dr. Pamela Gay or Bill Nye). With calendars, charts and graphs, you’ll treasure this definitive resource for many night sky viewings from now and for years to come.
