V1773 Cygni Star OR HD193536
V1773 Cygni is a main sequence star located in the constellation of Cygnus, The Swan. It is not part of the Cygnus constellation outline but is within the borders of the constellation.Based on the spectral type (B2V), V1773 Cygni colour is blue, which means that the star is one of the hottest stars in the Universe, hotter than our star[size=50].[/size]V1773 Cygni temperature in is the range of 10,000 to 30,000 Kelvin. V1773 Cygni effective temperature is 18,242 Kelvin which is hotter than the Sun's effective temperature, which is 5,777 Kelvin. Based on a parallax of 1.26, V1773 Cygni distance from Earth can be calculated at being 2,588.60 light years away or 813.01 parsecs.V1773 Cygni is a naked-eye star, so you don't need a telescope or binoculars when you look up on a clear night. The lower the magnitude, the easier it will be to see it.V1773 Cygni is a rotating ellipsoidal variable star. Variable stars are stars whose size and/or brightness changes over time. V1773 Cygni brightness ranges from 6.449 (dimmest) to 6.406 over a period of 2.9847 days.LBN 325 is a large emission nebula in the constellation of Cygnus.
The  distance of LBN 325 is estimated at 5,000 light years from Earth. The cloud consists mainly of hydrogen ionized by nearby stars. Cygnus is a northern constellation on the plane of the Milky Way, deriving its name from the LatinizedGreek word for swan. Cygnus is one of the most recognizable constellations of the northern summer and autumn, and it features a prominent asterism known as the Northern Cross (in contrast to the Southern Cross). Cygnus was among the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations.Cygnus contains Deneb (ذنب, translit. ḏanab, tail) – one of the brightest stars in the night sky and the most distant first-magnitude star – as its "tail star" and one corner of the Summer Triangle the constellation forming an east pointing altitude of the triangle. It also has some notable X-ray sources and the giant stellar association of Cygnus OB2. Cygnus is also known as the Northern Cross. One of the stars of this association, NML Cygni, is one of the largest stars currently known. The constellation is also home to Cygnus X-1, a distant X-ray binary containing a supergiant and unseen massive companion that was the first object widely held to be a black hole. Many star systems in Cygnus have known planets as a result of the Kepler Mission observing one patch of the sky, an area around Cygnus.Most of the east has part of the Hercules–Corona Borealis Great Wall in the deep sky, a giant galaxy filament that is the largest known structure in the observable universe, covering most of the northern sky.

In Eastern and World Astronomy
In Hinduism, the period of time (or Muhurta) between 4:24 AM to 5:12 AM is called the Brahmamuhurtha, which means "the moment of the Universe"; the star system in correlation is the Cygnus constellation. This is believed to be a highly auspicious time to meditate, do any task, or start the day.In Polynesia, Cygnus was often recognized as a separate constellation. In Tonga it was called Tuula-lupe, and in the Tuamotus it was called Fanui-tai. In New Zealand it was called Mara-tea, in the Society Islands it was called Pirae-tea or Taurua-i-te-haapa-raa-manu, and in the Tuamotus it was called Fanui-raro. Beta Cygni was named in New Zealand; it was likely called Whetu-kaupo. Gamma Cygni was called Fanui-runga in the Tuamotus.[3]Deneb was also often a given name, in the Islamic world of astronomy. The name Deneb comes from the Arabic name dhaneb, meaning "tail", from the phrase Dhanab ad-Dajājah, which means "the tail of the hen".

In Western astronomy
 In Greek mythology, Cygnus has been identified with several different legendary swans. Zeus disguised himself as a swan to seduce Leda, Spartan king Tyndareus's wife, who gave birth to the Gemini, Helen of Troy, and Clytemnestra; Orpheus was transformed into a swan after his murder, and was said to have been placed in the sky next to his lyre (Lyra); and the King Cygnus was transformed into a swan.Later Romans also associated this constellation with the tragic story of Phaethon, the son of Helios the sun god, who demanded to ride his father's sun chariot for a day. Phaethon, however, was unable to control the reins, forcing Zeus to destroy the chariot (and Phaethon) with a thunderbolt, causing it to plummet to the earth into the river Eridanus. According to the myth, Phaethon's close friend or lover, Cygnus, grieved bitterly and spent many days diving into the river to collect Phaethon's bones to give him a proper burial. The gods were so touched by Cygnus's devotion that they turned him into a swan and placed him among the stars.[5]In Ovid's Metamorphoses, there are three people named Cygnus, all of whom are transformed into swans. Alongside Cygnus, noted above, he mentions a boy from Tempe who commits suicide when Phyllius refuses to give him a tamed bull that he demands, but is transformed into a swan and flies away. He also mentions a son of Neptune who is an invulnerable warrior in the Trojan War who is eventually defeated by Achilles, but Neptune saves him by transforming him into a swan.Together with other avian constellations near the summer solstice, Vultur cadens and Aquila, Cygnus may be a significant part of the origin of the myth of the Stymphalian Birds, one of The Twelve Labours of Hercules.
