Not sure why, but I always want to make this nebula gold.

Preprocessing

Weighted Batch Preprocessing with 2x Drizzle

RGB

Spectrophotometric Color Calibration
SCNR
StarXTerminator, and discard starless background
Arcsinh Stretch (2x)
Generalized Hyperbolic Stretch
Morphological Transformation to reduce star sizes

Ha & SII

StarXTerminator
EZ Decon
NoiseXTerminator (Ha) or EZ Denoise (SII)
Arcsinh Stretch
Colorize Ha with PixelMath: R: 0.75*Ha / G: Ha / B: 0, then SCNR with 0.66
Colorize SII with PixelMath: R: SII / G: 0.25*SII / B: 0
Combine using PixelMath: ~(~SII & ~Ha)
Curves Transformation
Apply background mask (from EZ Decon)
Local Histogram Equalization Radius: 164, Slope: 1.5, Amount: 0.26

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.
