PDF-(DOWNLOAD)-Field Guide to Meteors and Meteorites (The Patrick Moore Practical Astronomy

It is said that astronomy is one of the few remaining fields in which amateurs can make a real contribution to science and nowhere is this more true than in the field of meteors and meteoritesAlthough meteors are isolated and unpredictable it is possible to predict when meteor showers usually associated with old comets are due they last a couple of days during which many meteors can be observed in a single night Equipment for watching counting and even measuring meteors can range from the simplest a chair to sophisticated allsky camerasWhat is unique about meteors in astronomical observation is that many survive entry into the Earths atmosphere and impact the ground the only easilyanalysed extraterrestrial material available to scienceWhat is unique about Richard Nortons book is that it is both a field guide to observing meteors and also a field guide to locating preparing and analysing meteorites In addition to giving the reader information about observing techniques for meteors this book also provides a fully detailed account of the types of meteorites how and where to find them how to prepare and analyse them It is thus the only complete book on the subject available at present.

Astrophysics is often -with some justification - regarded as incomprehensible without the use of higher mathematics. 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. \"This book serves as a comprehensive guide for using a Nexstar Evolution mount with WiFi SkyPortal control, walking the reader through the process for aligning and operating the system from a tablet or smartphone. The next generation Go-To mount from Celestron, this is compatible not only with the Nextstar Evolution but also with older mounts. It is the ideal resource for anyone who owns, or is thinking of owning, a Nexstar Evolution telescope, or adapting their existing Celestron mount. Pros and cons of the system are thoroughly covered with a critical depth that addresses any possible question by users.

Beginning with a brief history of Go-To telescopes and the genesis of this still new technology, the author covers every aspect of the newly expanding capability in observing. This includes the associated Sky Portal smartphone and tablet application, the transition from the original Nexstar GoTo system to the new SkyPortal system, the use of the Sky Portal application with its Sky Safari 4 basic software and Celestron WiFi adaptations, and discussions on the use of SkyPortal application using the Celestron adapter on older Celestron mounts. Comments and recommendations for equipment enable the reader to successfully use and appreciate the new WiFi capability without becoming overwhelmed. Extensively illustrated using actual screenshots from the program interface, this is the only guide to the Nextstar SkyPortal an observer will need.\" There are currently thousands of amateur astronomers around the world engaged in astrophotography at a sophisticated level. Their ranks far outnumber professional astronomers doing the same and their contributions both technically and artistically are the dominant drivers of progress in the field today. This book is a unique collaboration of individuals world-renowned in their particular area and covers in detail each of the major sub-disciplines of astrophotography. This approach offers the reader the greatest opportunity to learn the most current information and the latest techniques directly from the foremost innovators in the field today.Lessons from the Masters includes a brilliant body of recognized leaders in astronomical imaging, assembled by Robert Gendler, who delivers the most current, sophisticated and useful information on digital enhancement techniques in astrophotography available today. Each chapter focuses on a particular technique, but the book as a whole covers all types of astronomical image processing, including processing of events such as eclipses, using DSLRs, and deep-sky, planetary, widefield, and high resolution astronomical image processing. Recognized contributors include deep-sky experts such as Jay GaBany, Tony Hallas, and Ken Crawford, high-resolution planetary expert Damian Peach, and the founder of TWAN (The World at Night) Babak A. Tafreshi.A large number of illustrations (150, 75 in color) present the challenges and accomplishments involved in the processing of astronomical images by enthusiasts. There are many books covering different facets of astrophotography, but few of them contain all the necessary steps for beginners in one accessible place. Astrophotography is Easy! fills that void, serving as a guide to anybody interested in the subject but starting totally from scratch. Assuming no prior experience, the author runs through the basics for how to take astrophotos using just a camera?including cell phones and tablets?as well as a telescope and more sophisticated equipment.The book includes proven techniques, checklists, safety guidelines, troubleshooting tips, and more. Each chapter builds upon the last, allowing readers to master basic techniques before moving on to more challenging material. Also included is a comprehensive list of additional books and resources on a variety of topics so readers can continue expanding their skills.Astrophotography Is Easy! doesn’t simply teach you the basic skills for becoming an astrophotographer: it provides you with the foundations you will need for a lifelong pursuit. In 1996 Meade, the world\'s largest astronomical telescope manufacturer, introduced the ETX, a low-cost and genuinely portable instrument capable of results close to the theoretical limits of optical performance. Since then several different models have been introduced, most of them controlled by on-board computers that automatically point the telescope at objects selected from a database of 12,000. Unfortunately not all these objects are visible when looking through the ETX! (They are included because they can be imaged with special equipment.) Mike Weasner is a world expert on the ETX range, and describes the best 100 objects to start with, and offers hints and tips about using and looking after the telescope to get the best possible results.
