Description: A new version with better representation of the young, blue stars at the edge of the galaxy. I had big problems to conserve the colour. All processing was done in Pixinsight.
In the new version I have used "Division" instead of "subtraction" in DBE. This helped with the colour. Then I used ArcsinhStretch instead of HistoTrans. But with Arcsinh I got so ugly pink and green star. I tried RepairHSV, which did not really help. Then I returned to a combination of HistoTrans first (to saturate the bright stars and the galxy core) and then I applied Arcsinh. In the end I blended the image with one that was processed by HistoTrans only. This gave better result in the galaxy center,
I hope you like it and I welcome any tips and tricks to further improve.

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.
