The Rosette nebula! A rose in the sky from my backyard!

My first attempt in imaging the Rosette nebula has been realized without any filter!
And I spent really really (really!) several hours in the post-processing phase with PS, in order to extract as much as possible its signal and maintaining, at the same time, a controlled background-noise (my area is classified Bortle scale 5).
I created also a synthetic luminosity-layer in order to increase the signal, by using each color channel, so that the less-noisy channel (the green channel for my Canon EOS 550D used in that my first attempt) was as a background, and the remaining channels have been then added with a reduced-percentage in weight in that synthetic luminosity-layer composition. It was emotioning when the 'rose of the sky' started to appear in the post-processing phase, step by step carefully.
You can also find the Rosette nebula (without any filter!) in my gallery too!

I decided then to adopt a dual-band l-enhance filter in couple with my new astronomy camera and you cannot imagine my emotion when I saw
the first light-frame collected and roughly post-processed!
I had few time that night so the total integration time here is just 40min, but I'm looking at the first clear-night to shoot again the wonderful Rosette nebula
in all its magnificence!
The idea now is to compose light-frames got from the L-enhance filter in order to have the base clear-signal and full RGB light-frames to better obtained all the stars colors!

Here some other technical details for the sake of completeness:
Main camera QHY294c (gain 1087, offset 40, no cooler activated).
Guide camera: QHY5L-II with a 9x50 finderscope self adapted as a guide-scope!
Mount: Celestron AVX.

Any comment is much appreciated!

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.
