Description

This is the Soul Nebula or 👻 IC1848 👻. This image is a compilation of three narrowband channels (7nm): Sulfur-2, Hydrogen-alpha and Oxygen-3. It is shot over four nights during full moon. The refraction of moonlight causes more background noise to be visible, even with an integration time of about 16.5 hours... By assigning each of the three narrowband channels to a color (RGB) it allowed me to recreate that iconic Hubble palette.

Process involved:
  1. DynamicBackgroundExtraction on separate channels,
  2. SPCC,
  3. Color Calibration for evening the SHO levels,
  4. DarkStructureEnhance,
  5. StarXTerminator,
  6. BlurXTerminator on seperate stars and starless image,
  7. HistogramTransformation (stretching),
  8. NoiseXTerminator using a mask,
  9. boosting and adjusting colors using CurvesTransformation,
  10. PixelMath for merging the stars image back,
  11. final adjustments and star reduction/resizing using BlurXTerminator (stellar only).

Clear skies!
