Rosette Nebula closeup

I've always been captivated by the darker regions of the Rosette Nebula. In this closeup, I've captured my favorite filament (elephant trunk?) in it.

Preprocessing in PI:
- WBPP for calibration and cosmetization
- SubframeSelector to find best image by PSF signal
- StarAlignment
- NormalizedScaleGradient
- ImageIntegration
- IntegerResample to get bin2 images

Processing in PI:
- DynamicCrop
- DBE
- EZ decon on Ha
- LinearFit Oiii and Sii using Ha as reference
- STF and HT to stretch images
- StarXterminator
- PixelMath to combine into starless SHO image for nebula

Postprocessing stars:
- Remove stretch on Ha and Oiii
- Combine Ha and Oiii
- PCC
- STF and HT to stretch image
- CurvesTransformation
- SCNR
- Starnet to extract cleaner stars than StarXterminator
- HT to reduce noise around stars a bit more

Postprocessing Nebula:
- LRGBCombination using Ha as reference
- TGVDenoise
- ACDNR
- MLT to slightly sharpen image
- LocalHistogramEqualization with RangeSelection masks
- DarkStructureEnhance
- CurvesTransformation
- PixelMath to add stars back

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.
