Orion nebula - untracked with stock DSLR

My very first astrophoto. Focus is horrible and, being untracked, the exposure times were obviously overestimated, with clear star trailing. Still, I'm impressed with the result now that I have better skills at post-processing.

Canon EOS 7D Mk2 stock
Lens 70-200 f2.8, @100mm FL
Manfrotto tripod
Lights: 524 exposures, 2", ISO 1600
Used Darks and Bias, did not use Flat frames.

This is a new processing of the image. I'm including my original process back in January/2021, when I started astrophotography, just as comparison. What a difference!

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.
