ASTRONOMERS’ OBSERVING GUIDES provide up-to-date information for amateur astronomers who want to know all about what it is they are observing. This is the basis of the first part of the book. The second part details observing techniques for practical astronomers, working with a range of different instruments. The Moon is the most commonly observed of all astronomical objects. Here, Peter Grego provides a concise, readable description of the latest ideas about its origin, history and geology. This is followed by a detailed guide for amateur astronomers who want to observe the Moon. It deals with equipment and techniques for a wide range of instruments – including the unaided eye – and features many practical hints and tips for practical astronomers. In one book, here is all you need to observe the Moon with an understanding of just what it is you are looking at. .

You love sky watching and are excited by what you see through your telescope. You want to keep a record of what you see. You want others to see it. These are all good reasons to put down your pencil and pad and get started cybersketching! What is cybersketching? It is using a small computer, such as a laptop or a PDA, to make a sketch of what you see through your telescope or even with your naked eye. Particularly good subjects are the Moon and the brighter planets, but even deep space has much to offer a cybersketcher. Why cybersketch? Sketching what you see is a fantastic way not only to record what you see but to share it with others. Before imaging, sketching was the only way people had of sharing their discoveries. With all the fancy new imaging devices around, sketching has become something of a lost art. But it shouldn’t be! Not only is it an inexpensive and quick way to record and share what you see. It also helps you to hone your observational skills. Using a computer gives you a variety of exciting and fun tools to use and ways to make your sketches almost professional, so you can show them off and display them. In this book, Peter Grego outlines the evolution of cybersketching, with a brief review of the history of computers, hardware and software, and how to use the tools that are now available to astronomy buffs. If you are not sketching because you think it is old-fashioned, or if you are sketching using only a pencil and paper, read this book and see why you are missing out on some terrific new technologies that are easy to use and affordable to nearly everyone. Become an astronomical cybersketcher, and you will find that the time you spend exploring the night sky is even more rewarding than you ever imagined.

A special celestial event climaxes towards the end of 2013, the arrival, fresh from the Oort Cloud, of Comet C/2012 S1 (ISON). By all predictions, this comet was set to be one of the most dazzling comets seen in modern history.   Sky watchers will have already been primed for C/2012 (ISON) earlier in 2013 with the apparition of another naked-eye comet, C/2011 L4 (PanSTARRS), and following C/2012 S1 (ISON) there is the prospect of 2012 K1 (PanSTARRS) reaching naked-eye visibility in August 2014. And there will be other bright cometary prospects in the near future, if we take into account the latest predictions.   This book sets the scene for the arrival of Comet C/2012 S1 and those comets following it over the next few years. It explains how sky watchers and amateur astronomers can practically follow comets, observe them, and record them. This is also a guide on how to keep abreast of the latest cometary discoveries and how to use publications, websites, programs, and apps to visualize and plan observations. The book includes:   ·    descriptions of the nature, origins and observing history of comets ·    a detailed guide to seeing and studying what could be the greatest comet of modern times ·    specially prepared maps covering bright cometary apparitions of the next few years. ·    Illustrations of recent naked-eye comets and space probe images of large comets.
