The Tulip Nebula (Sharpless 101) is an emission nebula in Cygnus.
It lies at an approximate distance of 6,000 light years from Earth and has a linear diameter of about 70 light years.
It's apparent magnitude is 9.0 and it occupies an area of 16 x 9 arc minutes of apparent sky.

I used HSO palette with RGB stars. More than 33 hours of integration time, selecting only the best frames of the total valid frames captured (80%).

All c&c will be appreciated.
