Revised New General Catalogue

The New General Catalogue (NGC) is the best-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 space 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.

About The NGC / IC Project... (5503 words)
Most of the problems in the NGC are with the original positions and descriptions, coming as they did from many different observers using telescopes ranging in size from 2 inches to 72 inches, and relying on auxiliary instrumentation that ranged from nonexistent to state of the art.
Unfortunately, no new positions were determined for this long work, but lists of errata in the NGC were given; and the descriptions, with their frequent records of nearby stars, are valuable in identifying the objects which Hagen observed.
NGC numbers were often arbitrarily assigned to nearby objects without regard to the descriptions or to the known problems in the original observations.
