Description

At the heart of Cygnus lies this magnificent nebula called the Tulip Nebula or Sh2-101. I shot it during several nights over 3 weeks, totaling at 15,5 hours. A nice project to put some full-moon nights to use. A great target for Hubble-palette, altough the background nebulosity was a tough one color-wise
