I finally decided to do my first experience in DS.

With a site rated Bortle 8.9, it seemed almost impossible to me to image such objects. So I chose the ideal target M 42 which had all the required qualities, brightness and presence of both bright stars and cloudiness.
At the hardware level, I simply added a Meade 0.63 focal length reducer to increase the C11 from 2800 mm to 1764 mm. Which is still too much for the DS.
Without guidance, I also had to do short poses.

I realized on 26/01/2022 a first series of LRGB images, without taking into account the importance of noise and believing that with a stack, as in planetary, it would be little present.Fatal error..
I immersed myself in reading a book published by a world-renowned French astrophotographer, Thierry Legault "Astrophotographie", to understand the importance in DS of making offsets, darks and flats. On the other hand, it was possible to do without an L filter, which I did on the evening of 02/02/2022, in order to be able to collect more photons.
I did not use RGB filters for this new test. With the Siril software, I was able to process my images correctly, with offset and dark subtraction. No flat, more useful for the wide field, according to my reading.
It was "magical" to see the cloudiness appear on the screen!

Well, even if I am satisfied with this first result, I measure the limits on objects of lower magnitudes, without specialized equipment and with a Bortle 8.9 sky.

Thank you for your comments.

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.
