Beschreibungen
<P>In the last few years, cheap webcams have revolutionized amateur astronomy by providing a very inexpensive alternative to purpose-made astronomical CCD cameras, which use refrigerated imaging chips and are thus extremely expensive. Webcams are capable of more advanced work than 'normal' digital cameras because their simple construction makes it easy to remove the webcam's lens, allowing it to be interfaced directly to a telescope. Using a webcam is not difficult but most amateur astronomers who have tried to do this do not achieve the finest results, despite the webcam's potential. There are numerous imaging and image processing tricks and techniques, and all of them are needed to get the best results.</P>
<P>Along with webcam technology has come simple-to-use image processing and enhancement using a PC: the most powerful technique is, 'stacking' in which the best images (out of hundreds) are selected and summed automatically to provide startlingly good results.</P>
<P>"Lunar and Planetary Webcam User’s Guide" 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.</P>
<P>Glance through the images in this book to see just how much you can – easily – achieve by using a webcam with your telescope!</P>

<P>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.</P>
<P>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.</P>

Enables anyone with a modest telescope and a webcam to obtain jaw-dropping lunar and planetary images to rival those taken with mid-range astronomical CCD cameras costing $1000 or more Enables you to contribute scientific results about the Solar System…results that professional astronomers want De-mystifies - in an easy-to-read way - the jargon of webcams and computer processing Filled with the experts’ hints and tips on imaging (and understanding) the Moon and planets with a webcam Each observing target is dealt with separately, so specialised techniques are explained in context
<P>This book aims to de-mystify the jargon of webcams and computer processing and provides detailed hints and tips for imaging the Sun, Moon and planets with a webcam. It demonstrates how inexpensive technology is revolutionizing imaging in amateur astronomy. These advances have enabled anyone with a modest telescope and a webcam to obtain jaw-dropping lunar and planetary images to rival those taken with cameras costing thousands of dollars. A glance through the images in this book shows just what spectacular results can be achieved by using a webcam with a telescope. Each observing target is dealt with separately, so specialized techniques are explained in context. The book further explains how webcams can be connected direct to a PC so that software can be used to "stack" multiple images, providing a stunning increase in image quality.</P>
