I had about 5 more hours with the l-Pro but unfortunately the flats I took where not giving me good results and I'm about a month late from retaking them. I ended up deciding to leave it out and keep only the l-extreme data for an HOO Pinwheel Galaxy.

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
- DBE
- PCC
- EZ soft stretch

Postprocessing:
- Extract luminance and apply slight HT
- LRGBCombination using luminance
- CurvesTransformation
- TGVDenoise
- ACDNR
- StarXterminator
- MLT to slightly sharpen image
- LocalHistogramEqualization with RangeSelection masks
- PixelMath to add stars back
- 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.
