Revision title: Better palette

Introduction:
The Carina Nebula is pretty low at the moment and the nights are getting shorts in the Southern Hemisphere. It is definitely not the best target to shoot right now, but I had some bugs to investigate and had to test my new mount and way of setting up everything.
All in all, I'm just happy that I managed to capture light for almost the whole night, and I am particularly happy with the fact I didn't restart my processing 20 times before being happy with the result!
I may add more hours to this in the future and maybe or capture the cropped areas to make it a wider and more complete view of the nebula.

But for now, please enjoy my latest image!

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.
