<![CDATA[Veil Nebula]]> http://gallery.cuttinedgeobservatory.com/v/nebulae/veil/ The Hubble Space Telescope captured images of the nebula. The analysis of the emissions from the nebula indicate the presence of oxygen, sulfur, and hydrogen.
When finely resolved, some parts of the image appear to be rope like filaments. The standard explanation is that the shock waves are so thin, less than one part in 50,000 of the radius, that the shell is only visible when viewed exactly edge-on, giving the shell the appearance of a filament. Undulations in the surface of the shell lead to multiple filamentary images, which appear to be intertwined.
The nebula is notorious among astronomers for being difficult to see visually, even though it has a bright integrated magnitude of 7. However, a telescope using an OIII filter (a filter isolating the wavelength of light from doubly ionized oxygen), will allow an observer to see the nebula clearly, as almost all light from this nebula is emitted at this wavelength. Using an 8-inch (200 mm) telescope equipped with an OIII filter, one could easily see the delicate lacework apparent in photographs. With an OIII filter, almost any telescope could conceivably see this nebula, and some argue that it can be seen without any optical aid, excepting an OIII filter held up to the eye. This is also one of the largest, brightest features in the x-ray sky.
The brighter segments of the nebula are listed in the New General Catalog under the designations NGC 6960, 6979, 6992, and 6995. The easiest segment to find is 6960, which runs through the naked eye star 52 Cygni. NGC 6979 - the central portion of the Veil Complex is Pickering's Wedge, or Pickering's Triangular Wisp. This segment of nebulosity was discovered photographically by Williamina Fleming, but credit went to her supervisor Edward Pickering, as was the custom of the day, thus named after Pickering as a result.]]>
