The shape of this nebula resembles the continent after which it was named and covers an area more than four times the size of the full moon. The shape of the nebula resembles that of the North American continent, including the prominent Gulf of Mexico. Photographed or imaged, ngc 7000 bears a striking resemblance to the North American continent, hence its nickname the North America Nebula. NGC 7 000 bears a striking resemblance to the North American continent, hence its nickname the North America Nebula.
NGC 7000 is very faint, but quickly becomes a very bright and colourful object in dark skies. Photographed or imaged, NGC 7000 bears a striking resemblance to the North American continent, hence the nickname North America Nebula. Like most other famous nebulae in the night sky, NGC 7000 got its name because of its shape, which is reminiscent of the shape of the North American continent.
What is the name of NGC 7000?
This is an opportune time to photograph NGC 7000 as it is least affected by poor transparency and air turbulence. The image below is an image of NGC 7000 from the Digitized Sky Survey 2 (DSS2 – see imprint) taken in the red channel. NGC 6997 is definitely a star cluster, but it is quite old and probably did not form in the nebula. Other interesting objects in this area are the open star cluster Messier 29, the Veil Nebula, the Sadr region, the Crescent Nebula (NGC 688), the Soap Bubble Nebula (PN G75.5 1) and the Tulip Nebula (Sh2-10.
Is the North American Nebula visible?
In the above image, the 550 mm focal length of the telescope used (in combination with the camera’s magnification) was a little too “deep” to capture the entire nebula. Still, something must be wrong for him not to pick up any sign of it, perhaps his camera is not sensitive enough to hydrogen alpha radiation to capture the nebula. The small open star clusters NGC 6997 and Cr 428, which appear embedded in the nebula, are actually background objects that are in no way related to the North America Nebula. This also explains why the view changes so dramatically when I hold a nebula filter in front of my glasses.
However, with a UHC filter, which filters out some unwanted wavelengths of light, it can be seen without magnification in dark skies.
How far is the Pelican Nebula from Earth?
Popular telescope trip targets such as the North America and Pelican emission regions, the Butterfly Nebula (IC 131), and the Crescent and Veil Nebula can be identified by hovering the mouse pointer over the image. Dense gas slows the advance of this ionisation front, allowing parts of the molecular cloud to survive in its shadow. These huge columns of gas are found in many nebulae, and the material within them is often dense enough to collapse and form stars. However, it is the hot, massive binary star HD 199579 (6th magnitude) that makes the nebula glow.
The identity of the star that ionises the nebula’s hydrogen has long been uncertain and was thought by some to be Deneb, as the North American Nebula lies just 3 degrees east of the bright star.
What is the Cygnus Wall?
The image contains only part of this giant nebula, which is about 1600 light years from Earth. The Cygnus Wall as part of the North American Nebula (NGC 7000 or Caldwell 20) in the constellation Cygnus, taken with the Hubble Palette (SHO). This deep space object is an emission nebula consisting of an interstellar cloud of ionised hydrogen (HII) and a much smaller fraction of other gases (OII, SII and others). The North American Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, near Deneb (the tail of the Swan and its brightest star). The Cygnus Wall is located in the southern part of the North American Nebula and is one of the highest concentrations of star formations in this region.
