Inexpensive webcams are revolutionizing imaging in amateur astronomy by providing an affordable alternative to cooled-chip astronomical CCD cameras, for photographing the brighter astronomical objects. Webcams - costing only a few tens of dollars - are capable of more advanced high resolution work than "normal" digital cameras because their rapid image download speed can freeze fine planetary details, even through the Earth's turbulent atmosphere. Also, their simple construction makes it easy to remove the lens, allowing them to be used at high power at the projected focus of an astronomical telescope. Webcams also connect direct to a PC, so that software can be used to "stack" multiple images, providing a stunning increase in image quality. In the Lunar and Planetary Webcam User's Guide Martin Mobberley de-mystifies the jargon of webcams and computer processing, and provides detailed hints and tips for imaging the Sun, Moon and planets with a webcam. He looks at each observing target separately, describing and explaining all specialised techniques in context. Glance through the images in this book to see just how much you can - easily - achieve by using a webcam with your telescope!

Star clusters are among the most spectacular objects for amateur astronomers to observe and image. They represent the beginning, the present and the future of the universe, from sparse open clusters containing only a dozen stars, to giant globular clusters, each replete with a million suns. Part one of this detailed book provides a comprehensive review of star clusters - including open, globular, extragalactic, and even cluster remnants - along with their evolution and physics. Part two is about observing. The larger clusters can be observed through the most basic equipment - normal binoculars or budget telescopes - but Mark Allison talks about instrumentation and accessories, for observers from beginner to expert. Finally there is an observing guide and a comprehensive observing list for a wide range of telescope apertures. This one book provides all you need to observe star clusters, and to understand the many and varied objects that fall under this classification.

Using just a regular digital camera along with an amateur astronomical telescope, anyone can produce spectacular photographs of the Moon, as well as surprisingly good images of major planets. Purpose-made astronomical CCD cameras are still very expensive, but technology has now progressed so that digital cameras - the kind you use for everyday photos - are more than capable of being used for astronomy. Tony Buick has written this illustrated step-by-step manual for anyone who has a telescope (of any size) and a digital camera. Look inside at the beautiful color images he has produced - you could do the same. Much more than a manual of techniques and examples, this book also provides a concise photographic atlas of the whole of the nearside of the Moon - with every image made using a standard digital camera - describing important lunar features, including the sites of manned and robotic landings.
