I tried shooting M27 more than once, and each time I was surprised that when attempting color balance based on stars, the central part turned blue, even though it's a mix of red hydrogen and sea-green oxygen. The green disappears during processing. Many photographers have the same issue, and you do too.

There is no reliability here at all—just a simple white balance calibration and, yes, green removal was done. This is more of a test shot, the camera's first light. Now I'm waiting for clear skies to reshoot properly and try to get at least 4 hours of integration.
