图书描述

The objects listed in the Caldwell Catalogue supplement Messier's famous catalogue of 110 non-stellar objects, and they include some of the most fascinating objects for amateur astronomers. This comprehensive guide to the Caldwell objects has been produced specially for observers. Each object is conveniently on a double-page spread (which can even be photocopied for field use). There is a photographic image of every object and full technical data including position (with the major Star Atlas chart numbers) and NGC number. It also includes a finder map showing TelradTM circles, a star-hopping guide, a visual description of what the object looks like through amateur telescopes, and a physical description of the object itself. There is a fold-out map showing the location of all the Caldwell objects in the sky. Every practical amateur astronomer will find this an essential guide to observing the Caldwell objects.
