- 25 Stunning Sights Every Astronomer Should See
The idea of the Caldwell Catalogue came to me one night after I had been observing the Moon (my own subject) and had looked casually at the Perseus Sword-Handle. This has no Messier number. (Messier catalogued nebulae as 'objects to avoid' during his comet searches, and in any case limited himself to the northern part of the sky.) There are many Messier clubs. Why not draw up a catalogue of bright nebular objects omitted by Messier? I did so - and more or less on the spur of the moment, sent it off to Sky and Telescope. To my surprise, it caught on, and by now everyone seems to use the Caldwell numbers. I could not use M numbers because Messier and Moore begin with M - but my proper name is hyphenated (Caldwell-Moore), so I used C. All the Caldwell Catalogue objects are within range of modest equipment. They are arranged in declinations, so that to survey them all means some travel - but that is not a problem nowadays.

The New General Catalogue (NGC) is the most well-known catalogue of deep sky objects in amateur astronomy. It contains nearly 8,000 objects, known as the NGC objects. The NGC is one of the largest comprehensive catalogues, as it includes all types of deep sky objects (not specialised to just galaxies for instance). The catalogue was compiled in the 1880s by J. L. E. Dreyer using observations mostly from William Herschel, and then subsequently expanded with two Index Catalogues (IC I & IC II), adding nearly 5,000 objects.
Here is a list of the full 109 Objects in the Caldwell Catalogue and some details about them. It was compiled using information mainly from the Caldwell List Club and from Wikipedia.
You may also wish to look at the Messier Catalogue.
