Sh2-101, the "Tulip Nebula" as an anaglyph Red/Cyan 3D
You'll need Red/Cyan Eyeglasses to be able to see this image right.
Note, if you have a Red and Blue filters, you can use them! Red goes to Left eye.
Other 3D-formats:
NOTE! This is a personal vision about forms and shapes, based on some known facts and an artistic impression.

Tulip Nebula, Sh2-101, wide field & closeup, reprocessed
Since my processing technique gets better and weather doesn't give any support, I have reprocessed some older images. There is now star colors added and other processing is tweaked too.
Sh2-101, wide field
In constellation Cygnus
Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.
Nebula is imaged with a Tokina AT 300mm f2.8 camera optics and the QHY8 cooled astro camera.
Technical details with an original image.
The "Tulip Nebula", Sharpless-101, locates in constellation Cygnus, distance is about 6000 light years.
Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.
Original versions from November 2008, with technical details:
