Only 36 stars were known to be in this nebula but the Chandra telescope increased the number of known stars to 160. Lagoon Nebula: 110 ly (34 pc) [44] H II region: Veil Nebula: 100–130 ly (31–40 pc) [45] Supernova remnant: Located in the Cygnus Loop: NGC 3576: 100 ly (31 pc) [46] Emission nebula: N41: 100 ly (31 pc) [47] Emission nebula ...

The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues (abbreviated IC), describing a further 5,386 astronomical objects. Thousands of these objects are best known by their NGC or IC numbers, which remain in widespread use.
Caldwell advocates, however, see the catalog as a useful list of some of the brightest and best known non-Messier deep-sky objects. Thus, advocates dismiss any "controversy" as being fabricated by older amateurs simply not able or willing to memorize the new designations despite every telescope database using the Caldwell IDs as the primary ...
