Description - Observing the Caldwell Objects by David Ratledge
The objects listed in the Caldwell Catalogue supplement Messier's famous catalogue of 110 non-stellar objects, including 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 on a double-page spread (which can 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. The book also includes a finder map showing Telrad 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.
