The number of nebulae was then greatly increased by the efforts of William Herschel and his sister, Caroline Herschel. Their Catalogue of One Thousand New Nebulae and Clusters of Stars [16] was published in 1786. A second catalog of a thousand was published in 1789, and the third and final catalog of 510 appeared in 1802.
The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion, and is known as the middle "star" in the "sword" of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky with an apparent magnitude of 4.0.
Jones-Emberson 1 is a planetary nebula in Lynx, named after Rebecca Jones and Richard M. Emberson. Kleinmann–Low Nebula is a star-forming region found at the center of the Orion Nebula, named after named after Douglas Kleinmann and Frank J. Low. McNeil's Nebula is a variable nebula in Orion, named after Jay McNeil.
Planetary nebulae, which have nothing to do with planets despite the name, usually have a rounded structure and were so named because they initially resembled the disks from which planets form ...

The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus.The common name comes from a drawing that somewhat resembled a crab with arms produced by William Parsons, 3rd Earl of Rosse, in 1842 or 1843 using a 36-inch (91 cm) telescope.

Of the deep-sky objects of interest in Vela is a planetary nebula known as NGC 3132, nicknamed the 'Eight-Burst Nebula' or 'Southern Ring Nebula' (see accompanying photo). It lies on the border of the constellation with Antlia. [19] NGC 2899 is an unusual red-hued example. This constellation has 32 more planetary nebulae.
