I originally captured the data last September from a dark site (Bortle 2) but never posted the image on AstroBin. I finally took some time to re-process it by applying and experimenting with new techniques.
For this image I used an OSC astronomy camera and the main process was done in Siril.
Below is the workflow I followed:

Crop image
Background Extraction (Subtraction and Division modes)
Remove stars from linear image with Starnet++ and create a starmask
Stretch starless image using Generalized Hyperbolic Function
Non-linear noise reduction
Process the stars separately giving attention to color and intensity
Recombine stars with starless image

Final touches made in RawTherapee:

Increase Lightness
Increase Contrast
Selective color boost
Adjust color balance

I hope that you like the end result.

Clear skies!

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.
