The Cygnus Wall complex is part of the more recognisable North American nebula.
This ridge is approximately 20 light years long and is a huge star forming region.
You can see where it is in a larger picture on the following link www.swagastro.com/the-cygnus-wall-complex.html
This is a 4 pane mosaic as the field of view was too small to fit in the Cygnus Wall itself.

Cygnus Wall.
.....................
Cygnus Wall is the most visible and interesting part of the well-known North America nebula, located 1500 light-years from us, in the constellation Cygnus. The "wall" is actually an area of stellar dust combined with hydrogen ionized by the radiation of young stars and stretches over a length of about 20 light-years, thus being one of the largest and best known stellar "nurseries".

The Cygnus Wall is a ridge of intense star formation within the North America Nebula (NGC 7000), located approximately 1,500 to 2,600 light-years away in the constellation Cygnus. Its key facts include its location, size (about 20 light-years across), composition (gas, dust, and newly forming stars), and the role of nearby young stars in ionizing the gas, which causes it to glow red.

NGC7000 (1080 exp)
The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest star). The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico.
The North America Nebula is large, covering an area of more than four times the size of the full moon; but its surface brightness is low, so normally it cannot be seen with the unaided eye. Binoculars and telescopes with large fields of view (approximately 3°) will show it as a foggy patch of light under sufficiently dark skies. However, using a UHC filter, which filters out some unwanted wavelengths of light, it can be seen without magnification under dark skies.
Cygnus's Wall is a term for the "Mexico and Central America part" of the North America Nebula, shown in this image. The Cygnus Wall exhibits the most concentrated star formations in the nebula. It also resembles the letter W or a large bird taking off, if you look at it from the right angle.

Object: The Cygnus Wall in NGC7000 (HST* Palette).
The Cygnus's Wall is the term for a structure in the North American Nebula (NGC7000) that comprises the "Mexico and Central America part" of the overall nebula and exhibits the most concentrated star formation area in the complex of ionized gas. Located about 1600 to 1800 light-years away the structure is a shock front surrounded by dark gas and dust in the constellation of Cygnus the Swan.
This exposure of over 7.5 hours reveals the details using the *HST palette which is accomplished by combining sub frames using three narrowband filters that capture light produced by glowing hydrogen (Ha), oxygen (OIII) and sulfur (SII) present in the nebula. Green is assigned to hydrogen, blue to oxygen and red to the sulfur.

Nel cuore della costellazione del Cigno, a circa 2.590 anni luce dalla Terra, si erge la Cygnus Wall: un’imponente scogliera di gas e polveri, lunga quasi 20 anni luce, che brilla di un rosso ardente sotto la luce delle giovani stelle calde vicine. È la parte più luminosa della Nebulosa Nord America (NGC 7000), che nella nostra prospettiva ricorda il “Golfo del Messico”.
Dalla città, con il mio SkyWatcher 200/1000 e filtro SV220, ho inseguito pazientemente i fotoni di idrogeno emessi da queste nubi, raccogliendo la loro luce fioca e antica, viaggiatrice per millenni nello spazio, per trasformarla in immagine. Un frammento di galassia che unisce la precisione della scienza alla poesia del cielo.

Detail from my last image of the NA Nebula, using drizzle in DSS. Took some fancy footwork but got there in the end :)
My first narrowband image and a test image really, but excited about these results. The Cygnus Wall, a portion of the North American Nebula (NGC 7000) in the constellation Cygnus. The nebula is approximately 1,500 light years from Earth, and the Cygnus Wall spans about 20 light years. The Wall exhibits the most concentrated star formations in the nebula.
My favourite target for testing telescopes, the North America Nebula, NGC 7000, in Cygnus, with its companion Pelican Nebula to the right, aka IC 5070. The bright star Deneb is at upper right. An odd little red nebula is to the right of the Pelican, of unknown identity as it is not in Deep Sky Atlas, Millenium Star Atlas, TriAtlas or SkySafari.
This is a stack of 15 x 6-minute exposures with the Astronomics Astro-Tech 90CFT apo refractor and its 0.8x Reducer/Flattener for f/4.8, as part of testing, and with the AstroGear modified Canon R camera at ISO 800. On the AP Mach 1 mount and auto-guided with the Lacerta MGENIII stand-alone guider. No filter was employed here, other than the Optolong IR Cut filter installed in the camera itself by AstroGear, replacing the Canon sensor filter.
Stacked, aligned and processed in Photoshop. with Lumenzia luminosity masks applied to a starless layer created with RC-Astro Star XTerminator to bring out the nebulosity independently from the rich starfield. Plus layers with PhotoKemi Nebula action and ON1 Effects Dynamic Contrast filter applied to further enhance the nebulosity and contrast.
Taken from home on a very fine warm and dry night, May 12/13, 2023, though with few hours of darkness at my latitude of 51° N in mid-May.
I managed to grab 25 minutes of Sii data to add to the Ha & Oiii data on my #CygnusWall image between the clouds the other night. It needs a lot more data. Total integration time so far 135 minutes, no where near enough. #NGC7000 #nebula #Astronomy #Astrophotography #Space

The North America Nebula (left of centre) and the Pelican Nebula (at centre) complex in Cygnus, framed with the bright star Deneb. The Cygnus Arc of IC 5068 is at bottom. Smaller Sharpless catalogue nebulas are at upper right, notably Sh 2-112. The nebulas show up well despite this being a "stock" camera, with no filters employed.
The field of view is about 7.5° by 5°, similar to binoculars.
This is a stack of 5 x 5-minute exposures with the Sharpstar 61 EDPH III apo refractor and its 0.75x Reducer for f/4.4, and the old Canon 6D DSLR at ISO 800, all on the ZWO AM5 mount autoguided with the ASIAir, as a test of the combination of gear. Taken June 26/27, 2023 with the waxing Moon still up but low and setting, and the sky so near solstice was not astronomically dark. No filter employed and the camera is not modified. Nebulosity enhanced with a PK Actions Nebula Filter action and a Detail Extractor filter from Color EFX in the Nik Collection.
Near the star of Deneb are two clouds of ionized hydrogen with striking resemblances to two very earthly subjects. The larger cloud looks uncannily like the continent of North America, complete with the Mexican isthmus (actually, the Cygnus Wall, a region of new star formation), Florida, and a Gulf of Mexico. Just off to the lower right, instead of the Bahamas, is the Pelican nebula, a smaller cloud that is seemingly a silhouette of a pelican about to spread its wings and pointing its beak to the left. The bright region along the backside of the "pelican" is another rich stellar nursery.
Only recently has it been determined that the North America nebula is around 2590 light years from Earth.
Les Dentelles du Cygne (Sh2-103) forment un rémanent de supernova dont l'explosion remonterait à une dizaine de milliers d'années. Elles se situent dans la constellation du Cygne.

The North America Nebula a large emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest star). The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. This nebula covers an area about 4 times the size of the full moon.
The Cygnus Wall is a portion of the North American Nebula that's basically the Mexico / Central America region of the North America Nebula. The Wall spans about 20 light years and exhibits the most concentrated star formations in the entire nebula, as can be seen in the dense knots and clouds of gas that make up the wall itself.

This is just a small part of the North America Nebula. This is the part showing the central America and Gulf of Mexico area. In fact it is the main star forming area and is known as the Cygnus Wall. The wall is lit by bright young stars and partly hidden by dark dust clouds. This gives the amazing shapes that my image is trying to show.

The red emission Nebula called Cygnus Wall is the part of the North America Nebula (NGC7000) that resembles Mexico/Central America. The region is characterized by dark nebulas and dust lanes that give the scenery a dramatic attitude.
The image is a combination of a color image with a narrowband H-alpha image (12nm with unmodified DSLR).
The RGB image was made with a standard Pentax K3ii on a TS 130/910 refractor with 0.79x reducer. The blue/ red colors were generated by separating magenta and red in postprocessing and shifting the magenta more and more fto light blue. The now blue colors should represent OII emission regions while the red colors come from Hydrogen alpha emissions.
39 x 300 s exposures @ ISO 200.
In a second step a H-alpha narrowband was combined in Photoshop. This image was taken with the same unmodified Pentax K3ii (45 x 600s @ Iso 800 and 10 x 1200s @ ISO 400).

The well-known North America Nebula (NGC 7000), with the smaller Pelican Nebula (IC 5067) to the right, in Cygnus, taken in the deep red light of hydrogen and rendered here in monochrome. This shows the rich detail and structure in the nebulas.
This is a stack of 16 x 16-minute exposures with the Canon EOS Ra, on the SharpStar 94mm EDPH refractor with its f/4.5 flattener/reducer lens. The camera had a 12nm Astronomik clip-in H-a filter installed. The images were shot over two nights and with the Moon up for most exposures. Autoguided with the Lacerta MGEN3 stand-alone guider.
In processsing I used Lumenzia 10 to create luminosity masks on Curves layers to bring out the nebulosity. An application of the Star XTerminator plug-in for Photoshop created a starless layer that was blended back in selectively to eliminate or suppress stars to help accentuate the nebulosity and structure, but without a fully starless image which often shows pockmarked artifacts where the stars were. A high pass filter further snapped up the dark lanes and streaks. A colour grade adds the slight blue tint for artistic effect.
All stacking, alignment and blending with Photoshop 2022.
The North America Nebula (AKA NGC 7000 and Caldwell 20) is on the left and gets its name on account of its similar shape to North America with its prominent Gulf of Mexico. The Pelican nebula is to the right, again getting its name due its pelican like appearance. They sit approximately 1600 light years from Earth in the constellation Cygnus and span a combined distance of approximately 100 light years.

The North American & Pelican Nebula in HST.
This is a 2 pane mosaic totalling 17.5 hours of data, captured over 14 nights over the past 2 months. My first ever deep sky mosaic and probably my last for a while :-).
Here is a wonderful section of Nebulosity in Cygnus. This is the Cygnus Wall which is part of the North America Nebula. This wall is actually a region of star formation. This cosmic ridge spans about 20 light-years and lies about 1,500 light years away.
The wide field view picture contains both the North America Nebula and the Pelican Nebula which I took earlier in May.

Always an interesting and beautiful target, the Cygnus Wall is part of the North American Nebula (NGC 7000) in the constellation Cygnus.
The Cygnus Wall, a prominent region of star formation, is an integral component of the much larger North America Nebula (NGC 7000). Primarily composed of hydrogen and sulfur, it exhibits orange-red hues processed with an HOO palette, while oxygen is depicted in blue. Stretching approximately 20 light-years in length, it spans a distance of about 1.3 million times greater than the distance between the Earth and the Sun.
Gazing upon the night sky and contemplating its wonders fills me with humility and awe, prompting me to reflect on our great Creator and strive to follow Him more diligently.
Near the star of Deneb are two clouds of ionized hydrogen with striking resemblances to two very earthly subjects. The larger cloud looks uncannily like the continent of North America, complete with the Mexican isthmus (actually, the Cygnus Wall, a region of new star formation), Florida, and a Gulf of Mexico. Just off to the lower right, instead of the Bahamas, is the Pelican nebula, a smaller cloud that is seemingly a silhouette of a pelican about to spread its wings and pointing its beak to the left. The bright region along the backside of the "pelican" is another rich stellar nursery.
Only recently has it been determined that the North America nebula is around 2590 light years from Earth.
This image was composed using the "Hubble Palette".

Cygnus Wall & Pelican Nebula.
With clear (albeit patchy) skies last night, was able to get the extra data to complete this 2 pane mosaic in Ha & Oiii.
The Cygnus Wall (bottom left) an Pelican Nebula (right). This is all one Nebula, but a dark belt of dust sits between us and it, causing the dark areas down the middle.
This image shows Hydrogen and Oxygen gas.

Les Dentelles du Cygne (Sh2-103) forment un rémanent de supernova dont l'explosion remonterait à une dizaine de milliers d'années. Elles se situent dans la constellation du Cygne. Elle est aussi appelé boucle du Cygne, terme issu de la traduction littérale de son nom anglais (Cygnus Loop). Elle contient : la Grande dentelle (NGC 6995), la Petite Dentelle (NGC 6960) et le Triangle de Pickering (NGC 6979)
The Cygnus Loop is a large supernova remnant (SNR) in the constellation Cygnus. It is known as the Veil Nebula, also called the Cirrus Nebula or the Filamentary Nebula. Several components have separate names, including the Western Veil or Witch's Broom, the Eastern Veil, and Pickering's Triangle.

The Cygnus Wall portion of the North American Nebula (NGC7000) is always a fun and inspiring astrophotography target this time of year. An interstellar cloud of ionized hydrogen, the nebula is 2590 light-years away and about 140 light-years across. This area (the Cygnus Wall) in this HII ionized hydrogen gas cloud is thought to contain the most active area of star formation.
It is always fun to learn about the science of these objects but for me more exciting and inspirational to consider their magnitude, beauty, and grandeur in the amazing universe in which we live.
The image was captured with a ASI183MC Pro camera on a RASA8 scope.
