Revision title: complete new using Pixinsight now

Took this picture while on a trip in South of Belgium with my campervan
5hrs of 300s pictures with my basic TS70ED f6.8 refractor and the asi 533MC camera with L Extreme filter. On my portable mount EQM35pro
For now I prefer the starless version because I was not so pleased with how the stars turned out (I my replace them with mono RGB ones later on, as I will add also more Ha mono to it)
Bortle 4, moon at 93%

Description: I started over. I am new in pixinsight but I managed to split Ha and OIII and then recombined (after star removal and curves transformation). Maybe the "brain" looks a bit to pink/bluish now but I can see the surrounding Oiii gasses better. TO BE CONTINUED...

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.
