1. Open star cluster M 29 (NGC 6913)
open cluster M29, which can also be found under the name "Cooling Tower", is located not far from the bright star Sadr ( γ Cyg) and at a distance of 7000 light years from the Sun. The brightness of the cluster is 7.1 m , the angular size is 7′.
The gods were so outraged that they turned him into a swan. This is why today the swan rolls thoughtfully on the water, often sticking its head below the surface. This myth covers it all - the swan and the Milky Way analogy, as well as the behavior of the swan. Is there anything interesting to see within Cygnus? Just with the naked eye in a dark sky, you can easily see the cloudy Milky Way stretching across Cygnus. In the middle of this celestial bird, the Milky Way splits into two separate streams of stars.
Take a look through the binoculars to start and scan this area. This is a very beautiful region of space. If you have a telescope of any size feel free to practice it on this region of the sky. Indeed, there are more red and orange stars in this region of space than anywhere else in the sky. The red stars are striking. You will be rewarded for your search efforts. Return to the top of the cross, Deneb, and scan through the binoculars a little northeast of this star. If you have dark skies and your binoculars provide a wide field of view, you can see the North American Nebula, so called because this region of dust and gas resembles North America as seen on a map.
Due to the fact that the cluster is surrounded by a cloud of gas and dust matter that absorbs light, we cannot notice M29 with the naked eye. Even with binoculars or an amateur telescope at low magnification, the cluster is clearly and in detail visible.
Despite the high density of stars in the vicinity of the Sadr star, the desired open cluster M29 very easy to see in the optical finder of a telescope. Below is an atlas of the surroundings of Sadr or γ Cyg, where colored arrows mark objects accessible for observation through binoculars and deep-sky telescopes.
Dark skies are an absolute must to find this wonderful object. Use binoculars to find a large open star cluster north of Deneb. A small eyepiece on a small telescope will allow the object to fill the entire field of view. The four brightest stars in this group form a square. The cluster can be found with binoculars, but a low power telescope will improve the view. And then Cygnus has one of the best double stars in the sky. This is our old friend Alberio, the beak of the Swan or the lower end of the Northern Cross.
When the double observation was somewhat novel, each observer tried to outdo the other by describing the colors of the binary stars they observed. Scouts who visit us at the Seagrave Observatory are sure to love this description. Try to resolve the star into two components using a six-inch telescope.
2. Open star cluster IC 4996
IC 4996- a small (6 ′), but bright (7.3 m) open cluster in the constellation Cygnus. Removed from the Sun at a distance of 5200 light years. Includes only 15 stars, brightness from 8 to 13 magnitude s.
Weak companion bluish. The remnants of a supernova explosion long ago, the veil can be found at the Hyena. With the nebula filter and dark sky, you will be able to spot it easily. Without a filter, you will need a lot of patience and incredible sky conditions. The filter amplifies the emission spectra of the nebula, making them easier to detect.
Whether you use your eyes, binoculars, or a telescope, the Swan has a lot to offer. Unlike the Swan, which often keeps its head below the surface of the water, all you need to do is keep your eyes on the heavens. A popular name for the Swan is the Northern Cross, and its shape is much larger and different from the famous Southern Cross. In its cruciform shape, the Greeks visualized the long neck, outstretched wings, and strong tail of the swan flying across the Milky Way, in which it is embedded. The description of Aratus as hazy or hazy in patches is no doubt a reference to the Milky Way passing through it.
It is recommended to observe only with astronomical binoculars or a wide-angle eyepiece and at a low magnification. The density of stars in the background of the cluster is so high that distinguishing the desired deep sky may not seem like an elementary task. Maybe that's why at one time the open cluster was not included in the NGC catalog, but only later it was added in addition to it (IC - index catalog).
Mythographers tell us that the swan is Zeus in disguise, en route to one of his myriad love affairs, but its exact prey is the subject of some controversy. To avoid his unwanted advances, she assumed the form of various animals, first jumping into a river and then running across the ground before finally flying like a goose. Not to be outdone, Zeus pursued her through all these transformations, transforming into a larger and faster animal at every turn, until he finally became a swan, in which form he captured and raped her.
Hyginus tells a similar story, but does not mention the metamorphosis of Nemesis. Rather, he says that Zeus pretended to be a swan running away from an eagle, and that Nemesis gave the swan refuge. Only after she fell asleep with the swan in her lap did she discover her mistake.
On the atlas above green arrow indicated the location IC 4996. You can immediately try to find it in the finder, or start from the Sadr star, capture it along the way M29, and only then notice a little lower IC 4996. It's all there, you can't find it.
3. Diffuse Crescent Nebula (NGC 6888)
Albireo - the star crowning the head of the Swan
In both versions, the result was that Nemesis produced an egg which was then given to Queen Leda of Sparta, some say Hermes and others say in passing a shepherd who found the egg in the forest. The beautiful Helen hatched from the egg, later known as Helen Troy.
Leda was the wife of King Tyndareus of Sparta, which made the outcome much more difficult because she, too, slept with her husband that same night. According to one interpretation, she gave birth to one egg, from which the twins Castor and Polydeux hatched, as well as Helen. It was believed that the shell of this egg was displayed in a temple in Sparta, hanging from the ceiling with ribbons. To add to the confusion, Polydeuces and Helen were believed to be the children of Zeus, while Castor and Clytemnestra were the fathers of Tyndareus.

Fantastically beautiful and recognizable emission nebula "Crescent" or "Sickle" ( NGC 6888 or by C 27) has extended angular dimensions - 18′ × 13′ and a brightness of 7.5 m.
Unfortunately, in an amateur or semi-professional telescope, it does not look so expressive. Firstly, without a special narrow-band filter (for example, Baader OIII), you will not distinguish the nebula among the stars at all, and secondly, it can be seen only at low magnifications (up to 50x) as a dim gray arc. Astrophotographers often delight their subscribers and viewers with pretty images obtained when shooting the Deep Crescent Nebula and further post-processing in a photo editor.
Although Eratosthenes identified the constellation with the swan, Ptolemy followed Aratus, referring to him as an anonymous Bird in his Almagest 350 years later. Deneb and Albireo - plus a black hole. The most bright Star The swan, Deneb, marks the swan's tail; its name comes from dhanaba, the Arabic word for tail. Surprisingly, the Greeks did not have a name for this prominent star. It forms one corner of the so-called Summer Triangle of Stars, completed by Vega in the constellation Lyra and Altair in L'Aquila.
The key of the swan is marked by a star called Albireo, which is shown by small telescopes to be a beautiful colored double star of green and amber, like a celestial traffic light. German historian Paul Kunitsch traced the tortuous history of Albireo's name. This phrase itself was taken for an Arabic name and was rewritten as albireo. Therefore, the name Albireo, although it appears to be Arabic, is completely meaningless. Cygnus lies in the Milky Way and therefore contains many attractive star fields to sweep through binoculars.
In any case, if there is a narrow-band filter and the Moon does not shine "out there", then try and find the nebula. On the previous map, he indicated the direction with a blue arrow, it’s worth starting from the same Sadr star.
4. Open star cluster NGC 6910
The myth of the constellation Cygnus
In Chinese astronomy, the Milky Way was visualized as a celestial river, the Tianhe. Deneb and the eight stars on the wings of the Cygnus, including Gamma, Delta and Epsilon Cygnus, were known as Tientsin, the ford or bridge over the river. In this area, the river appeared to be shallower because, as we now know, a dark cloud of dust called "The Cygnus" obscures the light from the stars behind.
Crossing the opposite border from Lyra to Cygnus, there was a line of five stars ending in 4 and 8 Cygnus that formed Niandao, the route between the royal palaces. The evolution of modern man has long been one of the greatest mysteries of the time. When did "modern" humans first appear? When did they make the first art? When did they build the first temples? When were the first real cities built? And what inspired these events? These questions form a huge puzzle, but the pieces of the puzzle keep changing.
Before that, we were looking for three previous deep skys below the Sadr star, and now let's take a look at what kind of pearl shines right above the star γ Cyg - this is a beautiful open cluster NGC 6910. It has about 40 stars with a total area of 8′. The brightness of the cluster is 7.4 m. Removed from the Sun at a distance of 5300 light years.
When Sadr is in the finder, you can raise the telescope tube quite a bit and immediately notice a vertically elongated necklace of several shining stars. If you look through the eyepiece, you will be able to both count the number of stars in the cluster and distinguish the shades of the stars individually. A very attractive collection.
For example, which archaeological site around the world is considered the "first city?". Which specific caves contain "first art?". Almost every year, archaeologists announce the discovery of old building complexes and older art. Despite this problem, a number of recent events may have given us a startling answer.
In his latest book"The Cygnus Mystery" 1 the famous British novelist Andrew Collins may well have uncovered the key missing piece of the evolutionary mystery. His first clues were found in archaeological sites, but his search ended in space science and genetics. Collins begins by presenting a wealth of information from excavated ruins and ancient beliefs about the origin and destiny of the soul. As Collins was finishing the book, he discovered a startling fact about this particular region of the sky.
5. Open star cluster NGC 6883
Cluster NGC 6883 is an example of a very open cluster. In the image above, you can see about 15-20 bright scattered stars in the background of a diffuse nebula. This is the desired deep-sky object. The shades of stars are perfectly distinguished: from cold dark orange to hot blue. The total brightness of the cluster is 8 m , the angular size is approximately 35′. An excellent eyepiece choice would be a 2-inch or ultra-wide angle and a low magnification so you can capture the entire cluster.
In addition, many scientists, including Carl Sagan, have argued that cosmic rays provide the spark of human evolution. Now, recent developments in evolutionary genetics, regarding new area may have confirmed Collins correctly. Collins begins his book by describing the ruins of what archaeologists have called "the oldest temple site in the world." The site, Göbekli Tepe, is located in southeastern Turkey and is actually one of several such subsurface temple complexes in the region.
Looking at the location of the outer openings of the temples at Göbekli Tepe, Collins realized that the underground complex was clearly oriented to the north. The swan, referred to in the generic American tribal form as the Cross, is usually depicted as a swan or other bird, depending on the specific species of migratory bird found in a particular region. Collins then discovered Arabic astronomical knowledge regarding Cygnus, and he collected information from archaeoastronomers regarding alignments to Cygnus at other sites.
NGC 6883 lies in a plane parallel to a straight line passing through the stars γ Cyg and η Cyg(). Nearby there is another cluster ( NGC 6871), so try not to confuse them, or get to know both.
7. Open star cluster NGC 6819 (Fox Head)
The list of sites that archaeoastronomers have linked to Cygnus is amazing. In the Central and South America archaeoastronomers have found Cygnus lines at important sites in La Venta and Cusco. In North America, Collins himself discovered that the incredible complex of mounds and earthworks in Newark, Ohio centered on the Milky Way and Cygnus Rising.
Drawing attention to the incredible art found on the walls of deep caves in Europe, Collins found that archaeologists claimed that the oldest cave art actually depicted the constellation Cygnus. The reason why the Cygnus was so important to the ancients is most easily answered by the previously mentioned fact. But there is an even more intriguing aspect to this. The Cygnus lies at a critical location in the Milky Way known as the Great Rift. This is where the Milky Way splits into two long sides with a dark, dark area separating it.
Beautiful, large and very dense open cluster NGC 6819 was officially opened only in 1824. Its brightness is only 7.3 m, and the angular diameter is 5'. In astronomical binoculars or a finder, the cluster seems to be of a spherical type, but at high magnifications, the middle “sags” and the stars are clearly visible at the edges separately. The bright star nearby (in the upper left corner of the image) is a binary star with a brightness of 6.2 m, which is not resolved into separate components in amateur telescopes.
This is the exact location Milky Way served as a key element in many ancient religious systems. The most mysterious and important religious beliefs of ancient people concerned the origin and destiny of souls. The Milky Way and the Great Rift are special geographic locations central to ancient beliefs about the soul. For example, Native American religious beliefs hold that the souls of the departed follow a path or river to a specific location in the northern sky, often depicted in Native American art as the Northern Cross-Swan.
I do not fully understand, or rather I do not see at all the connection between the name "Fox Head" and appearance clusters. Can you see the similarities?
Below on the map in red and green arrows showed two approximate routes for finding the cluster. It is preferable to start with the already familiar Sadr star and move clockwise than from the star η Cyg and move up.
8. Open star cluster NGC 6834
Quite nondescript (compared to the previous ones) open cluster NGC 6834 located on the border with the constellation and has a brightness of 7.8 m, and an angular diameter of only 4 ′. It does not show any details with binoculars, with an amateur telescope you can distinguish the stars separately, but it is problematic to notice their shades. The cluster's brightest stars barely exceed magnitude 10. In total, there are about 50 stars in the cluster.
It is best to start the search from the double bright star Albireo ( β Cyg), whose brightness is 3.5 m. Why am I suggesting a somewhat "curvy" route to the congestion? Because practice shows that stars after the 6th magnitude differ very little in brightness, and when you turn the telescope tube without taking your eyes off the eyepiece (or finder), it is extremely difficult to understand with certainty whether you are moving in the right direction. But if there are stars of 3 - 5 magnitudes on the way, then there will be no doubt - you are on the right track.
Veil Nebula (Fishing Net or Cygnus Loop)
The remnant of a supernova that exploded about 6,000 years ago
9. Diffuse Witch's Broom Nebula (NGC 6960)
Admit it, who has never heard of Nebulae Veil(or the Fishing Net Nebula)? So this nebula is so huge (the remnant of a supernova that exploded several thousand years ago covered a distance of 50 light years or 3 ° relative to an observer from Earth) that its individual sections are highlighted in the catalogs under their own serial numbers. And the first one is NGC 6960 or nebula Witch's Broom.
The bright star in the center of the image is a double star. 52 Cyg brightness 4.2 m. As a rule, it is she who serves as an excellent guide when searching for a nebula. The visible dimensions of the "Broom" are 70' × 6'. In form, indeed, resembles a broom. It will be extremely difficult to see the nebula through a telescope without narrow-band filters.
I will not exaggerate if I say that this is one of the most photographed areas of the Northern Hemisphere of the sky by amateur astronomers. Good astro and photo reports can be found on the blog pages astrobel.ru (
10 Diffuse Nebula NGC 6992
Continuing the analysis of the components of the Veil Nebula, the next step is the NGC 6992 nebula. The angular dimensions are almost the same as those of the previous nebula - 60 ′ × 8 ′. It has several more saturated areas and with the use of an OIII light filter it is possible to distinguish color inhomogeneities.
11 Diffuse Nebula NGC 6995
Closes the top three most interesting "pieces" of the Veil Nebula - diffuse nebula NGC 6995. Its dimensions are 12′ × 12′. In a telescope, it looks like an inverted (mirrored) copy of the previous nebula.
If we turn to the star map, then the Veil Nebula or Fishing Net lies in the south of the constellation, on the border with the constellation. Nearby there are several bright stars (up to 4th magnitude), which will be easy for the observer to navigate.
12. Open star cluster NGC 7063
Tautological but open cluster NGC 7063 indeed scattered. 30 - 35 stars with a brightness of 9 - 15 magnitudes are scattered over an area of 9′ × 9′. The total brightness of the cluster is 7 m . Visible even with binoculars. The colors of the stars are clearly visible through a telescope. A brighter dozen of stars were concentrated in the central group, which imperceptibly separated from the stars on the periphery.
The cluster is located in the southwestern part of the Cygnus constellation and is located at great distances from neighboring deep skys. Nearby there are a couple of bright stars ( τ Cyg and σ Cyg 3.85 and 4.2 m, respectively). They will be a good start when looking for clusters. NGC 7063(as well as the planetary nebula NGC 7027).
Search for the cluster NGC 7063 and the nebula NGC 7027
13 Planetary Nebula NGC 7027
And here is the first planetary nebula in the constellation Cygnus - NGC 7027. Despite the available magnitude for amateur telescopes (8.4 m), its angular dimensions are too small - 0.3 ′ × 0.2 ′. Although, in fact, the planetarium gives a brightness value of only 10.9 m. In a 254mm telescope and 120x magnification, the nebula looks like an oval speck with "broken" edges.
On the atlas above green arrows from the star ν Cyg the direction to the desired "planetary" is shown. If you have experience of being NGC 7027, then write in the comments, share your impressions.
14. Open star cluster NGC 6866
Another nice open cluster NGC 6866 in the constellation Cygnus. Its brightness is 7.6 m, and the angular diameter is slightly less than 7'. It includes about 50 stars with brightness from 10.5 to 15 magnitudes. In the vicinity of the cluster, brighter giant stars are clearly visible, which create contrast and grandeur of the seen picture as a whole.
Below is a general map for the next four deep skys. Actually search NGC 6866 you can start from the familiar and already familiar star Sadr. But it would be more correct to find a double star in the finder 30 Cyg and lower the telescope tube half a degree down. The third option - we find the star Rukh ( δ Cyg brightness 2.9 m) and rotate the telescope counterclockwise.
Search for deep skys in the northeastern region of the constellation Cygnus
15. Planetary Nebula NGC 6884 (NGC 6766)
A planetary nebula lost among other clusters NGC 6884 is the result of the end of a star's life. It was discovered relatively recently, in 1883. The apparent stellar magnitude is close to the limit - 10.9 m , and the angular diameter is only 0.25 ′ (just imagine that the size of the Ring Nebula ( M57) in the constellation is 2.5 ′, that is, 12 times more).
To observe the nebula, you will need at least a 12-inch (300 mm) telescope. "Planetarka" NGC 6884 located near a double star 30 Cyg, which simplifies its search and increases the chance of detection.
16. Open star cluster NGC 6811
The first thing that catches your eye when looking for some information about this open cluster NGC 6811 is a detailed and detailed description on the Russian version of Wikipedia. As a rule, only a small part of popular deep-skys can be found on Wiki, and for most of them a separate page has been created with a table of the most accessible characteristics (size, brightness, declination) and not always an image. I don't have an answer why there is so much information for NGC 6811.
So, NGC 6811- an open star cluster with a total brightness of 6.8 m and an apparent size of 15′. From the bright star Rukh ( δ Cyg) cluster is very easy to find. On a clear night, deep sky can be seen even with binoculars. Among the thousands of scattered stars, a cluster of densely spaced bright dots is clearly visible. The brightest stars in the cluster have a magnitude of 9.8m. But the total number of stars in the cluster is colossally large (compared to other open clusters) - about 1000. The brightness of most of them is greater than magnitude 15 and the stars are inaccessible to amateur telescopes.
17. Planetary Nebula NGC 6826 (Shimmering Nebula)
At the center of a planetary nebula NGC 6826 there is a star around which a cloud of gas and dust is noticeable. If you look at the nebula directly, then apart from the star you will not see anything, if with peripheral vision, a nebula appears around the star. In this regard, the "planetary" and received the name flickering.
Recently ( August 5, 2016) Ruslan Emirov, blog author star-hunter.ru shared an observation of this nebula. Read more.
The brightness of the nebula is 8.8 m, the angular size is 0.6′. Available for observation with a 130mm telescope. When using a narrow band filter, the star in the center of the nebula disappears, but some details are added near the nebula itself.
There is a bright binary star θ Cyg near the desired deep sky, from which I would recommend starting the search. Moreover, on the way you will meet the optical binary star 16 Cyg.
The next group of deep sky objects is geographically located in the northwestern part of the Cygnus constellation. Most objects can be found by searching from the brightest star in the constellation Deneb (α Cyg). Some of them are easier to find by first focusing on the star ρ Cyg, whose brightness is below 4 m . Therefore, I immediately give a star map of this section of the sky.
Map of the northwestern part of the constellation Cygnus
18. Diffuse Nebula North America (NGC 7000)
(image clickable)
Another visiting card of the famous constellation Cygnus is a nebula North America or NGC 7000. If you rotate the image up 90 degrees clockwise, then the nebula will resemble the continent of North America.
Unfortunately, like the Veil Nebula, this region of interstellar gas looks great in photographs and attracts a lot of attention from amateur astrophotographers, but shows little when using binoculars and a telescope. Angular dimensions - 120' × 100', brightness - 4 m .
There are several open clusters on the territory of the nebula. One of them NGC 6997.
19. Open star cluster NGC 6997
Very dim (consists of 15 - 20 stars of 10 - 13 magnitude) and small (8′) open cluster. When photographing in the background (more correctly in the foreground), the North America Nebula is noticeable ( NGC 7000).
20. Open star cluster NGC 7039
Another (previous) NGC 7063) a bright representative of a cluster of the "scattered" type - NGC 7039. Separating the cluster from other stars is very difficult. Despite the available brightness (7.6 m) and a large area (25 ′), the cluster consists of hundreds of dim stars from 12 to 16 magnitudes. The two bright stars in the image above (6th and 7th magnitude) have nothing to do with the cluster.
open cluster NGC 7039 located above the North America Nebula or slightly to the right of the brightest star Deneb.
21. Open star cluster NGC 7062
We continue to replenish the piggy bank of open clusters. Meet the star cluster NGC 7062. Apparent stellar magnitude - 8.3 m, angular diameter - 5 ′.
In fact, clusters like NGC 7062 are found spontaneously. On the strip of the Milky Way, when you lead a finder or look through an eyepiece, you involuntarily come across one or another star cluster. Often you don't even realize that this is one of the New General Catalog (NGC) or its supplement (Index-Catalog IC). In such wanderings, almost any two-inch eyepiece (for example, ) will work best. This is an indescribable pleasure, it is at such moments that you understand and never doubt for a moment how infinite and limitless the Cosmos is!
22. Open star cluster NGC 7067
Cluster NGC 7067 consists of about 25 stars with a brightness of 11 to 15 magnitudes. The total brightness of the cluster is 9.7 m , and the angular dimensions barely exceed 3′. This star cluster, surprisingly, is somehow “detached” from the canvas of stars. Thus, the search for it is simplified. It is only worthwhile to understand that the brightness close to 10 for an open cluster is very low and you will need a telescope with at least 150 millimeters and a bit of patience to find the desired star island among all the bright points.
23. Open star cluster NGC 7082
Bright and pretty open cluster NGC 7082 was discovered by William Herschel in 1788 when he aimed his telescope at this area of the celestial sphere. The apparent stellar magnitude is 7.2 m, the angular diameter is 24 ′ (for comparison, remember the diameter of the full moon is 30 ′). Thus, a wide-angle eyepiece and a magnification of up to 50x will be the best option for exploring the star cluster. In the photo above, different shades of stars are visible, among which there are both hot light blue giants and cooled yellow and orange dwarfs.
24. Open star cluster M 39 (NGC 7092)
Charles Messier at one time was able to find and add to his catalog only two deep skys from the constellation Cygnus, and both open clusters. Compared with M29, this cluster is considered the brightest in the constellation. The apparent stellar magnitude is 4.2 m, with an apparent angular size of 42′ and is 820 light years away from the Sun.
The cluster is perfectly visible even to the naked eye (if you know exactly where to look), and in 10-15x binoculars it looks amazing. And, by the way, more than once I met advice from experienced amateur astronomers that on a clear moonless night, the cluster M39 can be used as a starting point to the Cocoon Nebula ( IC 5146).
Below is a map of the open cluster search M39 and adjacent deep skys, which were considered a little earlier. On the map red arrows indicated the direction to the clusters from a bright star (magnitude 3.95 m) ρ Cyg.
25. Reflection-Emission Nebula Cocoon (IC 5146 or C 19)
IC 5146- this is not just a diffuse nebula, but an open star cluster immersed in a reflection-emission nebula. The star magnitude of this dip-sky is 7.2 m, and the angular dimensions are 10 ′ × 10 ′.
It is strange that the nebula is not listed in the New General Catalog (NGC), and in addition it is only in the sixth thousand.
At the center of the nebula is a 9.7 m star, which can be seen even in a small amateur telescope. With the use of a special narrow-band filter, the star fades and the nebula saturates. The dark silhouette in the form of the letter "X" is not badly distinguished. Around the nebula and on one side (look at the picture above) is a dark nebula, or more precisely, a cloud of interstellar dust.
When searching for a nebula, an open star cluster comes to our aid. M39 or a bright star 81 Cyg.
26. Open star cluster NGC 7031
Weak and small open cluster. Due to the high concentration of background stars, it is not possible to clearly distinguish the cluster, its boundaries and contours. I am even almost sure that both amateurs and scientists cannot fully name the exact number of stars in the cluster. The brightness is 9.1 m and the angular diameter is 15'.
It is located even to the north of all previous deep skys. The search is recommended to start from the cluster M39 or several nearby bright stars (5 - 6 magnitude).
27. Open star cluster NGC 7086
Saturated with dim (from 11 to 16 magnitude) deep-sky stars, the object looks very attractive in a wide-angle eyepiece and a magnification of up to 50x. You know, like beads scattered on the sand. This refers to hundreds of small stars against the background of even smaller ones.
The apparent stellar magnitude of the cluster is 8.4m, and the angular size is 12′. Located strictly above the cluster M39. On the map above, the green arrow marked the direction from the star Azelfafage (or 80 Cyg).
28. Open star cluster NGC 7128
NGC 7128- the northernmost (of the available in an amateur telescope) open cluster in the constellation Cygnus. It includes about 130 stars of different brightness and spectral class. The brightest star is an orange giant with a magnitude of 9.5 m. The total brightness of the cluster is 9.7 m , the angular diameter is 4′.
In a 50-year-old textbook, I found a funny map of this particular cluster: the direction to the north is indicated, there is a ruler and each star is numbered:
29. Planetary nebula NGC 7008
planetary nebula NGC 7008- the most difficult deep-sky object in the constellation Cygnus to search for in an amateur or semi-professional telescope.
Despite the dimensions of the nebula (1.43′) sufficient for recognizing contours and outlines, the brightness is close to the 11th magnitude. Unfortunately, telescopes with a primary mirror diameter of up to 10 inches (or 250 millimeters) are unlikely to be able to show at least something in this nebula.
I thought for a long time about the route to the "planetary" and, honestly, I could not come up with a good and reliable one. In a neighboring constellation Cepheus there is a good starting star with a luster of 4.5 m. It is from her that you can try to pave the way to the nebula NGC 7008.
30. Spiral galaxy NGC 6946 (C 12)
Probably no one believed in the presence of at least one galaxy in the constellation Cygnus. So meet - NGC 6946- barred spiral galaxy (type ). It is turned towards us, which is why the surface brightness is low, only 14 m. The apparent stellar magnitude is 9 m , and the angular dimensions are 11.5′ × 9.8′. It is available for observation in telescopes with a primary mirror diameter of 150 mm or more.
In many astronomical forums and portals it is found under the name Fireworks.
Geographically located right on the border with the constellation Cepheus. The search for a galaxy should start from the brightest star Cepheus - Alderamin(2.45 m).
Multiple star systems
31.1 Double star Albireo (β Cyg)
Albireo- a pair of stars that is very beautiful and accessible for observation even in amateur telescopes, which consists of a red giant of the 3rd magnitude and a blue component of the 5th. The distance between them is 34.2″.
31.2 Double star Rukh (δ Cyg)
Roc is a binary star that consists of a giant of spectral class B and a main sequence star of class F. The period of revolution of the secondary star around the main is 300 years. The distance between the components is 2.5″.
31.3 Double star ψ Cyg (24 Cyg)
ψ Cyg- a double star with a total brightness of 4.95 m. It consists of a main component with a brightness of 4.9 m and a secondary component with a brightness of 7.4 m. The angular distance between a pair of stars is 3.2″.
31.4 Double star 52 Cyg
52 Cyg- a double star with a total brightness of 4.2 m. It consists of a main component with a brightness of 4.2 m and a secondary one with a brightness of 8.7 m. The angular distance between a pair of stars is 6″.
31.5 Double Bessel star (61 Cyg)
61 Cyg- a very beautiful double star, named after the German astronomer and mathematician Friedrich Bessel. Consists of two orange dwarfs of magnitude 5 and 6. The distance between the stars is slightly more than 50″. The smaller component has a companion star, the brightness of which does not exceed the 15th magnitude. The system is removed from the Sun at a distance of 11 light years.
That's all for now. Got the text? Was he worth it? In any case, at least briefly get acquainted with more than thirty deep-sky objects in one trip, I doubt that it will work out. Thus the constellation Swan
Constellation Cygnus
“Today, the veil of mystery begins to be removed from the mysteries of the constellation Cygnus. In many places on the planet, the golden path of the Cygnus begins to open. The path of cognition of the Soul, the path of uniting disparate fragments of one big picture of Life, written on Earth by the Creator.
Many people feel vibrations and their hearts begin to beat in unison with other hearts around the world. This Rhythm, Quality and Light open new era- Age of Aquarius.
Cygnus is the constellation of the northern hemisphere of the sky, the Lyra constellation with the brightest Vega is located to the west of the constellation Cygnus, and in the east the "square" of the constellation Pegasus is visible.
“From the south, towards the Cygnus, the Eagle is rapidly “flying”, which is clearly visible thanks to its brightest star Altair.” Two stars, Deneb and Albireo, together with Vega (α Lyrae) form the so-called "Summer Triangle" - the famous asterism, with which Cygnus is so easy to find in the sky.
The figure shows a schematic representation of this constellation with its characteristic cruciform pattern, stretched along the Milky Way; its modern astronomical name is the Northern Cross asterism.
It is interesting that it was in it that in 1846 on the star Jenach (ε Cygnus) the planet of secrets Neptune was discovered.
Asterism The Northern Cross, which determines the characteristic shape of the constellation, includes the stars - α (Deneb), β (Albireo), γ (Sadr), δ and ε Jenach (Hyena). In the center of the crosshairs is the bright star Sadr, who in many myths played the role of the guardian of cosmic time.
In the outlines of the constellation, the ancients saw a flying bird: the Babylonians "forest bird", and the Arabs - "chicken".
“The Cygnus may have been the first constellation mapped in Mesopotamia, as some of the tablets depict a large star bird” (B. Brady).
Swan - ancient constellation, it is included in the catalog starry sky Claudius Ptolemy "Almagest" under the title "Bird". The stars of this constellation, according to Ptolemy, act like Venus and Mercury. This constellation is also mentioned in the writings of the ancient Greek mathematician and astronomer Eudoxus of Cnidus in IV BC.
It so happened that the Arabic vision of the starry sky is still present in the names of many stars, and it has become fixed in the names. So, for example, the brightest star of the constellation Cygnus Deneb (α Cygnus) is the “tail of the chicken”, and Albireo (β Cygnus) is the “beak of the chicken”.
Man has always looked at the sky and endowed this or that group of stars with earthly qualities. This is how "real star tales about constellations" appeared. Why real? Because everything happens on Earth according to the stellar scenario written by God, and people in whose horoscopes one or another star is strongly highlighted, fulfill their roles.
Or maybe this is a genetic memory of ancient events, just somewhat transformed by legends and mythology?
In the Tales of the Slavic-Aryan Vedas it is said that “our Ancestors arrived from the Lands located in the constellations Ursa Minor, Orion, Cygnus ( Ursa Major) and the White Leopard or Pardus (Beta Lion).
The first to arrive in Summer 460530 were the Da'Aryans, who settled the continent at the North Pole of the planet, which the star travelers called - (Dar Ariyam - Gods).
According to contactees, "An extraterrestrial civilization from the planet Aria of the Dessa system with a star was the first to discover the planet Earth in the vastness of the Galaxy and found it suitable for settlement."

The Celestial Cross - the constellation Cygnus during the daily rotation of the Earth moves in a circle around the pole of the world - the North Star, as if making a heavenly "procession".
