Last image for my Cygnus project is the Tulip nebula.
Image is a narrowband color image in different versions.
There is three version of this image here, first image is Hubble palette composition. S-II =RED, H-alpha = GREEN and O-III = BLUE
Second version is a "natural" color composition from narrowband channels, H-alpha 100% + 35%S-II = RED, O-III = GREEN and O-III 100% + 30%H-alpha = BLUE.
The third version is with suopressed stars to show the complex shapes of the nebula.

This image is a starless BW version.
It shows a three dimensional nature of this object very well, I think.
