Description
For this image I used the same narrowband data as for my recently posted Rosette nebula image in the Hubble palette.
The beauty of narrowbanding is that you are free to combine the data to your liking. Here I tried to show the nebula closer to its 'true' red color, while emphasizing blue OIII data. For this, I used the following mix:
Red channel: 50% Sll + 50% Ha
Green channel: 20% Ha + 80% Olll
Blue channel: Olll
As there is no preferred direction in space, there also is no correct orientation for deep sky astro images. I therefore rotated the image 180° to show why the Rosette nebula is inoffically called Skull nebula.
Can you see the skull?
