Galactic Nebulas

Find here some pictures of nebulas taken in natural colors. Some of them are taken with narrowband filters. Since the narrow band light is dominating, in this case the color impression is no longer “realistic“.  Most are RGB shots, so they should be „true color“. Sometimes a portion of „narrowband light“ has been added in order to improve the scene. I aimed always to obtain a realistic color impression of the photo.
