The Art of Processing

Transforming raw data into a visually stunning masterpiece involved a rigorous processing workflow, primarily utilizing PixInsight and followed by fine-tuning in Photoshop and Lightroom.

• Pixinsight Suite:
  • GraXpert for gradient removal
  • SPCC for color calibration
  • BlurXterminator for sharpening
  • NoiseXterminator for noise reduction
  • Initial GHS (Generalized Hyperbolic Stretch) for stretching the data
  • StarXterminator to isolate stars
  • Second GHS stretch to further enhance details
• Post-Processing:
  • Curve adjustments in Photoshop for fine-tuning the overall look
  • Star recombination to reintegrate stars
  • Final touches and color correction in Lightroom

This detailed approach ensures that every nuance of the Tulip Nebula is brought forth, creating a truly captivating image for all to enjoy.
