David Ratledge Livres

The objects listed in the Caldwell Catalogue supplement Messiers famous catalogue of 110 non-stellar objects, and include some of the most fascinating objects for amateur astronomers. This comprehensive guide has been produced specially for observers, with each object conveniently shown on a double-page spread. There is a photographic image of every object and full technical data including position and NGC number. It also includes a finder map showing TelradTM circles, a star-hopping guide, a visual description of each object as seen through amateur telescopes, and a physical description of the object itself. Finally, there is a fold-out map showing the location of all the Caldwell objects in the sky. A practical and essential guide.

Charge-coupled Devices (CCDs) have revolutionised astronomy. Even affordable CCD cameras can be ten times a sensitive as photographic film, and they deliver a digitised image that is easy to enhance using a personal computer. David Ratledge has brought together contributions from twelve leading amateurs from around the world, people who are routinely producing astronomical images of a quality that rivals those of professional observatories only of 10 years ago. These experts describe their techniques and solutions, and offer essential tips and advice for anyone who is choosing or using a CCD camera. Now glance through the Colour Gallery at the back of this book to see just what they have done!
