NGC 6888 - The Crescent Nebula
Imaged in Hydrogen Alpha and Oxygen III. Approximately 5.5 hours exposure time, the colour palette is made up from applying Hydrogen to red and Oxygen to both green and blue. A Luminance channel from a blend of both the Hydrogen and Oxygen data was applied over the top of the colour image in Pixinsight.
The Astrodon OIII filter has captured the outer Oxygen shock wave nicely.
Imaged with an Altair Astro 6" RC and Atik 314l+, processed in Pixinsight and CS5.
