NGC 6888 in HST-palette
Last night I got S-II (ionized Sulfur) for the NGC 6888, the Crescent Nebula.
Now it was possible to compose a HST version (Hubble Space Telescope palette).

NGC 6888 in H-alpha and O-III light.
This was hard to process...
I have problems to have images calibrated with Flats, Bias and Darks, so much extra work there to have images balanced.

O-III, ionized Oxygen, really add forms to this image.
I will shoot S-II, even though there is much that in the Crescent itself.
I'll like to make this image to HST-palette as well.

A new project, NGC 6888
I have started a new project with the NGC 6888.
So far there is 4,5h of H-alpha.
Image going to be a three band narrowband image, I have allready 4,5h O-III light for this.
