While processing the RGB data from Spain, I discovered that a dewdrop had stubbornly clung to the protective glass of the camera chip, leaving an unsightly artifact in the color image.
I had simultaneously photographed the object in Presberg using the dual rig.
So, I took the Presberg color image, adjusted the alignment and framing, and replaced the color information with it. Of course the shape of the secondary mirror struts and of the stars differ from the Elephant-data, but since I removed the stars for the H-alpha and O3 information, it wasn't a major issue in this case.
In my opinion, the abundance of colorful stars in the middle of the Milky Way contributes to the overall impression of the image, even though the presentation of the glowing gas filaments is indeed better in a starless version.
