Messier 81, same data, new process

I've been using the very same data that I used in the other Messier 81 image but this time, all calibrated subs were 4x4 binned as I wanted to see what I can make out of it. This is the result, based on my limited post-processing skills. Although the resolution has been drastically reduced, I personally think that the overall image detail hasn't suffered. En contraire, one can see more faint details that I'd say you cannot enhance in the full-scale image without highlighting too much noise.

(Note: There's a glitch in the flat correction leading to an artifact. I'm not telling you where. If you don't see it immediately, it's a rather good sign.)

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.
