Testing different Gainlevels to stack Rosetta Nebula

Revision title: Rosette Nebula in SHO, Stars revised

Last night there was 2h CS. Since this is not really enough for any object, as far as my assumption, I thought, do an experiment. Instead of x times the same sub (gain and exposure time), I played with the thought, what happens if I stack different gain and exposure times. I chose the Rosette Nebula since I've done it before and it's also reasonably bright.
Total 75min
Per Ha, Sii and Oiii it is one sub, each Gain 100 600s, Gain 100 300s, Gain 200 300s and Gain 300 300s.
So, only 4 x Ha, 4 x SII and 4 x OIII
No darks, flats, etc... just a BadPixelMap.
I am really surprised how good this turned out, but I don't know why at the moment. More tests will follow.

Description: I took again a bit of time to recreate the Rosette Nebula out of the same data. Now I focussed more on the star-color but also some more details and color.

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.
