H-alpha + 20%S-II = Red, O-III = Green and O-III + 15% H-alpha = Blue

Now I have S-II (Ionized Sulfur) and O-III (Ionized Oxygen) channels, so making fullcolor image is possible

Pelican project continues
Last night I was able to capture more lights for the target.
Now there is 18 x 1200s H-alpha filteret light, Six hours.
I place here a small preview gropped from the image.
-
Next I'll shoot O-III and S-II channels for the color image,
Weather doesn't look too good now though.
