12 degress of celestial magic

[Adreneline]

Four imaging sessions mosaic taken over three nights covering the region from NGC7000 to NGC6888 - North American Nebula to the Crescent Nebula.

The image comprises 12 x 120s exposures of Ha and OIII for each session using an ASI1600MM-Pro Cooled and Samyang 135mm lens unguided on an iOptron CEM25-EC.

The mosaic was assembled in AstroPixelProcessor. PixInsight was used for BackgroundExtraction and HistogramStretch prior to combining in PixelMath. The resulting image was then transferred into Photoshop for iterative application of Levels, Curves and Selective Colour and finally Dfine2 to reduce noise across the image.
