An emission nebula in the constellation Cygnus.
 Located at a distance of about 6000 light years.
 Apparent size 16' x 9'.
 Siril scripts were used for the first time:
 CosmicClarity_Sharpen
 CosmicClarity_Denoise
 
 A much more interesting object located very close to the "Tulip" is the X-ray source Cygnus X-1, discovered in 1964.
 It is the location of a black hole.
 A blue supergiant star orbits around it, feeding the rotating accretion disk, which results in relativistic jets of high-energy particles being ejected perpendicular to the accretion disk.
 One of these jets collides with a denser region of the interstellar medium, forming a glowing, curved bow shock wave; this shock wave is my future target.
 It is quite large, resembling a horseshoe, but the object is very faint.
 If you are interested, search Yandex for: "Cygnus X-1 and the bow shock wave", it is quite impressive and there are photos.
