Edit info. Added image revision C, now selected as the final one.

Original image revision: "First light using the ZWO asi294MC pro cool camera and the 2" Triad Ultra Quad-Band Narrowband Filter in a light polluted sky."
Radian Triad Ultra 2" Quad-Band Narrowband Filter (optcorp.com)

Only one raw frame was taken in the bright moon light @Amager, CPH, DK.
The color frame was calibrated with master dark & flat frames and debayed with Fitswork4 SW.
The image contain a lot of noise & perfect round stars are missing due to work-in-process on my eq.
On purpose the color saturation level is only moderate.

CCDStack2 & PS programs was used for the calibration & the final image processing effort.

As usual it's taken in a light polluted area, Bortle 6 sky looking south, Bortle 7 sky the other directions/surroundings.
My home build observatory is placed in my front yard/in the "red light" pollution zone, have a look here,
Red Zone

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.
