NGC 6888, also known as the Crescent Nebula, is a faint emission nebula in the constellation Cygnus. Although it glows with a magnitude of 7.4, its extremely low surface brightness requires a very transparent night or large optics combined with a nebula filter to detect it. Some astronomers believe that the gas in a nebula like ngc 6888 is excited to glow by the ultraviolet light from the Wolf-Rayet star. Some astronomers believe that the gas in a nebula like NGC 6888 is excited to glow by the ultraviolet light from the Wolf-Rayet star.
Those of you who want to photograph NGC 6888 with an unmodified DSLR should not expect to see much more than the western outer arm of the structure in a single shot. Some astronomers believe that the gas in a nebula like NGC 6888 is excited to glow by the ultraviolet light from the Wolf-Rayet star. Wikipedia NGC 6888, also known as the Crescent Nebula, is a faint emission nebula in the constellation Cygnus.
How old is the Crescent Nebula?
Although the Crescent Nebula is very bright, many amateurs find it difficult to capture a detailed portrait of the area. Images of the Crescent Nebula, NGC 6888, and facts about this beautiful low-sky emission nebula powered by an ageing Wolf-Rayet star. In larger telescopes (20 cm or more), you can see the shape of a crescent or Euro sign, leading some to call it the Euro Sign Nebula. Larger telescopes can see a central bar within the crescent, giving the nebula the appearance of a “Euro sign”.
The Crescent Nebula, or ngc 6888 as it is officially known, is a prominent emission nebula with an extent of about 25 light years and is located about 5,000 light years from Earth in the constellation Cygnus.
How big is the Crescent Nebula?
The central star is classified as a Wolf-Rayet star (WR 13), which sheds its outer shell in a strong stellar wind, ejecting the equivalent of the Sun’s mass every 10,000 years. If you provide an email address, you can receive an email notifying you when someone else has added a comment to the same page. The central star is nearing the end of its stellar life, which will probably end in a spectacular supernova explosion. A 10 telescope with a wide-field eyepiece is recommended to see the gases that form the Crescent Nebula.
Is the Crescent Nebula a planetary nebula?
We decided to include it in this post because it can reveal some more details in the image, including the Soap Bubble Nebula. The Crescent Ne bula is special because it is usually classified as an emission nebula, but it has several features similar to those of planetary nebulae. Also known as NGC 6888, the Crescent Moon was formed when its bright, massive Wolf-Rayet central star WR 136 shed its outer envelope due to a strong stellar wind. One of the objects on the list is Ju 1, a very faint hydrogen-alpha nebula that is very difficult to see in photographs.
The nebula is made up of luminous gases that come from the bright star at its centre (an old star classified as a Wolf-Rayet star), and they are illuminated by the energy of this star.
