Bortle 7 suburban zone

Drizzle 2x

===Narrowband color processing===
Each channel: DBE, MMT noise reduction, Masked stretch
SHO in PixelMath

===Luminance processing===
Ha as luminance
PSF Image Creator - Harmut v. Bornemann
Protect background with range mask
Deconvolution, 10 iterations
7 5 3 1 wavelet layers

Fix star rings:
StarXTerminator on original stretched Lum to create star mark
Stretch star mask with histogram transformation as needed to fully cover rings
Apply mask on deconvolved image to protect all but stars
Pixelmath original Lum (before deconvolution) onto image. Can do multiple times if rings remain.

Noise reduction on Lum:
Copy lum, stretch, clip lights to create strong mask
apply mask, invert to protect lights
MMT noise reduction

Masked stretch; select background with preview window

Add contrast with LocalHistogramEqualization (Mask off background, 350 kernel radius)

===LRGB===
Apply Lum to RGB with LRGBCombination
StarXTerminator
Starless image:
Color calibration
Contrast curve
Saturation
Curves with color masks
Reapply Lum

===RGB Stars===
RGBcombination of RGB filters
PhotometricColorCalibration
Register to LRGB
Masked Stretch
HistrogramTransformation
Apply luminance of stars pulled from LRGB (StarXTerminator)
Add RGB stars with PixelMath
NoiseXTerminator

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.
