This image was acquired during the period July 29-August 10 2020 when there were hot 25C+ nights and humidity at times in the low 90s. Also, moon made an appearance and light pollution was especially bad. The object is faint and needed 10min subs so processing was a challenge. With Blink and SubframeSelector 93% of the subs made it to final processing.

Linear processing in Pixinsight:

Calibration with darks, flats and flat darks

CosmeticCorrection

Registration and Integration with WeightedBatchPreprocessing script

MureDenoise

DynamicBackgroundExtraction -- critical step that required lots of experimentation with sampling

Deconvolution

DynamicCrop

Non-linear processing:

BackgroundNeutralisation with aggregated background preview

TGVDenoise for luminance and chrominance

Sharpening with MultiscaleLinearTransformation

LocalHistogramEqualisation

SCNR

CurvesTransformation and saturation boost

MorphologicalTransform to reduce intensity of stars

Correction of magenta stars -- Invert, SCNR to remove green,Invert

Fine tuning of noise with MMT

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.
