Sharpless 101, also called Sh2-101 is a Region HII nebula and also an emission nebula in the constellation Cygnus. It is also called the Tulip Nebula because it is shaped like a tulip in the images, cataloged by astronomer Steward Sharpless, the creator of the catalog in 1959. It is at a distance of about 6000 light-years from Earth and is close to the microquasar Cygnus X-1, site of the first black hole discovered.
A work of 27 hours of image acquisition in different filters Ha,S[II],O[III] and the classical RGB filters for the stars. In the FOV of the image also appears the first black hole discovered and confirmed as such Cygnus-X1. We can see a HII region occupying the entire CCD field and an interstellar medium full of information.
First light after the move of the observatory to a remote astronomical complex (astrocamp) in one of the last dark skies of continental Europe.
