The 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 from Earth.

This image is 7.5 hours with luminance and RGB exposures. H-alpha has been blended into the red channel. The imaging sequence began on October 3 for 4 consecutive nights. The image is still a bit noisy so I'll try to add some more exposure time.
