I was always convinced that it was possible to work out even more details than what I have achieved so far. To do this, I have spent hours testing many things and gaining experience. Finally, I have succeeded. After the stack in APP and before combining the channels, I have now worked out a process per channel which contains over 20 steps. The result, or rather the goal, was to bring out the faint areas better, minimize the noise (but not simply with a denoising tool), keep the stars small and clean, and bring out the brighter areas. The great thing is that after this processing, the channels are now still available to me as linear FITS and I can do the processing as usual afterwards. Hope the result pleases and gladly feedback or constructive criticism.

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.
