I've been shooting a lot with the Optolong l-extreme lately and wanted to try something different from the usual red HOO palette that this filter is known for. I'm really liking this golden HOO palette and will definitely use it a bit more in my next images with this setup.

Preprocessing in PI:
- WBPP for calibration, cosmetization and debayaring
- StarAlignment
- SubframeSelector to find best image by PSF signal and weight
- LocalNormalization using best image by PSF
- ImageIntegration using best image by weight as reference
- DrizzleIntegration using scale of 1 as anything else was generating artifacts in the stars

Processing in PI:
- DynamicCrop
- PixelMath to split into Ha and Oiii layers
- DBE
- LinearFit Oiii using Ha as reference
- EZ soft stretch
- PixelMath to combine into HOO image (stars)
- StarXterminator on Ha and Oiii
- PixelMath to combine into golden HOO image (nebula)

Postprocessing stars:
- LRGBCombination using Ha as luminance
- TGVDenoise
- ACDNR
- StarXterminator
- CurvesTransformation
- SCNR

Postprocessing nebula:
- LRGBCombination using Ha as luminance
- TGVDenoise
- ACDNR
- MLT to slightly sharpen image
- LocalHistogramEqualization with RangeSelection masks
- DarkStructureEnhance
- CurvesTransformation
- PixelMath to stars back
- EZ star reduction
- final CurvesTransformation

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.
