NGC 2237 and others - Rosette Nebula (Rosettennebel), colorful stars and the Mira Variable "IRAS 06326+0513" (HaRGB)

When comparing my image from last year (February 2022) and my current image, which mainly contains frames from this year (February 2023), I noticed that one star has almost "disappeared".
My research has shown that this star is a "Mira Variable" (Mira variable - Wikipedia).
In the box of "Revision B" I have compared the frames from February 2022 and the frames from February 2023. The images in this box are just soft processed.
The quality of the frames from February 2023 is better than the quality of the frames from 2022, because I used autoguiding in February 2023, but I think the visual change of the Mira Variable "IRAS 06326+0513" is very evident.

In these nights I cooled the camera down to an average of about -10 °C / 14 °F.

Hope you like it.

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.
