Rosette Nebula in bicolor

Revision title: PI Original RGB channels

This is my version of the wellknown Rosette nebula, or NGC 2237. It is located just east of Orion in constellation Monoceros at 5 000 lightyears distance
and it is about 130 ly in diameter.

This is the first time I have used Pixinsight for image processing. Due to that, I did it in several versions and compared results
with my normal processing routines. I would welcome any comments on the different revisions. In my previous bi-color images I have
been having problems with bllue fringes on the stars, and in this case I have taken several measures to avoid them, such as reducing exposure
time and processing the nebula data separately with stars removed.

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.
