PixInsight Workflow

Pre-Processing:

Master Super Bias from library.
Master Dark from library.
Master Flats per set from Super Bias and Master Dark Flat from library.

ImageCalibration
CosmeticCorrection
SubframeSelector (Weight, choose reference files and approve)
StarAlignment (Generate Drizzle Data)
LocalNormalization
ImageIntegration (Modify Drizzle Data)
DrizzleIntegration

Now have individual, unstretched Ha, Sii and Oiii files.

Post-Processing:

StarAlignment
DynamicCrop
DynamicBackgroundExtraction
LinearFit
TGVDenoise
MultiScaleMedianTransform
ArcsinhStretch
ChannelCombination (Sii - Red, Ha - Green, Oiii - Blue)

Now working with stretch RGB file.

BackgroundNeutralization
Invert Image
SCNR (Green to remove magenta from stars)
InvertImage
CurvesTransformation to adjust Hue to taste.

Starnet to create starless image.
PixelMath to adjust starless image (1-(1-$T)*(1-$T) )
HistogramTransformation on starless image to increase contrast

PixleMath to blend starless image with RGB (F=0.4; (1-(1-$T)*(1-s)*F)+($T*~F) )
LocalHistogramEqualization
MultiscaleLinearTransform
CurvesTransformation to adjust saturation, mask, as needed
MorphologicalTransformation for star reduction

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
