Sh2-101 Nebula in Cygnus
The Tulip Nebula, or Sharpless 101 (Sh2-101) 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 from Earth.
One of many interesting objects that are visible in hydrogen band in Cygnus. FOV of my setup [FSQ with ST8300 and ST2000 next] can present at least 5-6 obejects in Cygnus using Ha signal as luminance. This picture was created by combining Ha with RGB signal mainly used for stars.
The Tulip 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.
