Here is the summary of the lesson “SHO (or RGB) processing with PixInsight”:
 
1) Process Icons, cropping and alignment, extraction and processing before histogram transformation
- Download SHO process icons
- Installation of new processes on pixInsight such as Xterminator processes
-ScreenTransferFunction
- Cropping with DynamicCrop
- Alignment of SHO (our RGB) images with StarAlignment
- Lightness creation
- Gradient extraction with AutomaticBackgroundExtractor
- Star reduction and sharpening with BlurXterminator
- Noise reduction with NoiseXterminator and/or TGV Denoise
 
2) Histogram transformation and processing of lightness details
- Histogram transformation
- Star extraction with StarXterminator or Starnet2
- Exaggeration of details with HDRMultiscaleTransform on lightness
- Creation of masks
- Exaggeration of contrasts with LocalHistogramEqualization on lightness
- Process Clone Stamp to erase imperfections
 
3) Creation of the SHO combination
- Process Icons created by Photon Millenium
- Reinforcement of layers
- Mixing multiple SHO combinations with PixelMath
- Color saturation
- Reintroduction of the lightness layer.
 
4) Star processing
- RGB combination of stars
- Image Solver
- Calibration of images by spectrophotometry
- Removal of SCNR green noise
 
4) RGB combination
- RGB combination thanks to LRGB Combination
- Color calibration by spectrophotometry
 
5) Finishes
 
Appendix :
- Stacking and preprocessing with the PixInsight WeightBatchPreprocessing process
- Sorting photos with the Blink process

Do you want to achieve a professional result using PixInsight? Did you know that the processing of images from the James Webb Space Telescope is carried out in part using PixInsight software?
 
Learn about creating SHO images, which is the color palette used by the Hubble Space Telescope to create breathtaking photos. Whether you have a color or monochromatic camera, we teach you the process and how to achieve stunning results.
 
This lesson is also valid for color processing (RGB) with a monochromatic camera. We also indicate the process to follow.
 
We offer you the process icons of the SHO (or RGB) treatment, a detailed pdf of the procedure, a procedure in the form of a cheat sheet to allow you to automate the process as well as an appendix teaching you the stacking , preprocessing and sorting your astrophotography easily with PixInsight.
