Sh2-101
Image Description and Details : Sharpless 101 (Sh2-101) is a H II region emission nebula located in the constellation Cygnus. It is sometimes also called the Tulip Nebula because it appears to resemble the outline of a tulip when imaged photographically. It was catalogued by astronomer Stewart Sharpless in his 1959 catalogue of nebulae. It lies at a distance of about 6,000 light-years (5.7×1016 km; 3.5×1016 mi) from Earth.
Sh2-101, 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. The companion star of Cygnus X-1 is a spectral class O9.7 Iab supergiant with a mass of 21 solar masses and 20 times the radius of the Sun. The period of the binary system is 5.8 days and the pair is separated by 0.2 astronomical units. The black hole has a mass of 15 solar masses and a Schwarzschild radius of 45 km. A bowshock is created by a jet of energetic particles from the black hole as they interact with the interstellar medium can be seen as an arc (bluish) to the right of the "Tulip".

The Tulip
Image Description and Details : This colourful region, located in the constellation Cygnus, has many distinct views of energized gas, all of which give a deep sense of wonder and amazement. The night sky is wonderful, always look up!
We are star dust.

SH2-101 Tulip Nebula
Image Description and Details :
A real challenge! Through the smoke of Canadian forest fires, during a full moon and under a Bortle 9 sky, I took this picture of the Tulip Nebula (SH2-101) with about 10 hours of exposure in SHO from Montreal. I struggled with the processing, especially to bring out the weak OIII signal…
Interesting thing here, we can see the Cygnus X-1 binary system (above the Tulip nebula on the picture). It is a high mass X-ray binary system, it is a galactic source of X-rays. It was the first source of this type to be considered as a black hole.
