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 Catalogue of Nebulae and Clusters of Stars was first published in 1786 by William Herschel in the Philosophical Transactions of the Royal Society of London. [1] In 1789, he added another 1,000 entries, [2] and finally another 500 in 1802, [3] bringing the total to 2,500 entries. This catalogue originated the usage of letters and catalogue ...
This is a list of diffuse nebulae. Most nebulae are diffuse , meaning that they do not have well-defined boundaries. Types of diffuse nebulae include emission nebulae and reflection nebulae .
Pages in category "Nebulae" The following 23 pages are in this category, out of 23 total. This list may not reflect recent changes. ...
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 ...
