Crescent Nebula

The Crescent Nebula, NGC 6888. Seven filters were used to acquire the data for this image. Three typical narrowband filters captured the luminance from Ha, SII and OIII. In addition, a sequence of frames was shot with a clear filter, then three sequences capturing the red, green and blue wavelengths. The seven images were combined by mapping to RGB channels and to layers using additive modes. Technical details can be found in the notes for the Gamma Cygni region image elsewhere in this portfolio.
