Here is M45, resulting from my first experiments with my TS-UNC 200/800. Nothing is perfect here but I am indeed quite happy with the outcome.
86x120s
TS UNC Quartz 200/800
1x GPU coma corrector
L-Pro ASI294MC Pro
SVBONY 106 for guiding
ASI120MM
EQR-6 pro
APT, Siril, StarNet++, Astrosurface, GIMP
Up to now, I identified the following issues

spikes are doubled but nonetheless parallel, suggesting a focusing issue. As I did focus witht the bathinov tool of APT, which is quite sensitive, I need to continue looking for the cause of the problem.
stars are not round, contrary to my very first tests. Collimation is confirmed good by CCD inspector (2.7-4.9 arcsec off, which is acceptable). Polar alignment and guiding were excellent during the sesssion.
I need to increase total intergration time. That will likely improve the rendering of grey dust and background.
I need to buy a rotator to get all *seven* sisters.

Any suggestion is much welcome !

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.
