Information about Sh2-101
Tulip Nebula, or Sharpless 101 (Sh2-101) or the Cygnus Star Cloud is an
emission nebula located in the constellation Cygnus. It is so named
because it appears to resemble the outline of a tulip when imaged
photographically. It was catalogued by astronomer Stewart Sharpless in
his 1959 catalog of nebulae. It lies at a distance of about 6,000
light-years (5.7×1016 km; 3.5×1016 mi) from Earth.
nebula, at least in the field seen from earth, is in close proximity to
microquasar Cygnus X-1, site of one of the first suspected black holes.
Cygnus X-1 is the brighter of the two stars (lower star) in close
vertical proximity just to the right of the Tulip nebula.

Information about NGC 6888
Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is
an emission nebula in the constellation Cygnus, about 5000 light years
It was discovered by Friedrich Wilhelm Herschel in
1792. It is formed by the fast stellar wind from the Wolf-Rayet star
WR 136 (HD 192163) colliding with and energizing the slower moving wind
ejected by the star when it became a red giant around 250,000 to
400,000 years ago. The result of the collision is a
shell and two shock waves, one moving outward and one moving inward. The
inward moving shock wave heats the stellar wind to X-ray-emitting
