NGC 7000 The North American Nebula

I processed this image similarly to images of M31, M45, and the Scutum region, all taken with the same camera and lens under dark skies. Yet it is much less red than other images of the North American Nebula to be found on the web - a veil of pale blue reflection nebulosity seems to overlie the H alpha emission clouds. I wonder if most other photographers pump up the red, in an effort to match H alpha images or from some belief that the true color is much redder. This result seems close to natural to me.
