Here is the summary of the lesson “LRGB+ processing with PixInsight”:
 
1) Process Icons, cropping and alignment, extraction and processing before histogram transformation of the lightness layer
- Download process icons
- Installation of new processes on pixInsight such as Xterminator processes
-ScreenTransferFunction
- Cropping with DynamicCrop
- Alignment in the case of several images (e.g. RGB+Ha) with StarAlignment
- Lightness extraction
- 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
- Creation of masks
- Exaggeration of contrasts with LocalHistogramEqualization
- Process Clone Stamp to erase imperfections
- Star treatment
- Reintroduction of stars in the lightness layer
 
3) Color layer processing
- Gradient extraction with AutomaticBackgroundExtractor
- Color calibration using two methods: 1) SpectrophotometricCalibration with Image Solver process and 2) BackgroundNeutralization + Color Calibration
- Star reduction and sharpening correction with BlurXterminator
- Noise reduction with NoiseXterminator or TGV Denoise
 
4) Histogram transformation, color processing, mixing of layers with luminance and RGB+HA (or others)
- Histogram transformation
- Noise reduction with ACDNR
- Color saturation
- Reintroduction of stars
- LRGB Combination process for reintroduction of lightness
- Pixelmath for mixing different layers (e.g. RGB+Ha)
- Finishes
 
Annex :
- Stacking and preprocessing with the PixInsight WeightBatchPreprocessing process
- Sorting photos with the Blink process
 
Process Icons:
- 2 PixInsight Icons process files for luminance and color processing included with the course
 
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?
 
Although it is paid software, discover all the ins and outs of color processing of nebulae or galaxies by mixing them with any other Ha layers. 
 
We offer you the process icons of the 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, the pretreatment and the sort your astrophotography easily with PixInsight.
