M45 w/Canon 400mm 7DII

After a couple of failed attempts at M45 as a newbie last winter, I have finally got a nice image after its back in season and I have a year under my belt. Same equipment, dslr & lens on tracker, except guiding this time. Last time I shot slightly stopped down, but the diffraction spikes from the aperture blades really obscured all the detail in the nebulosity! Shot wide open at f5.6 this time. I didn't have matching darks when I stacked it, and for some reason the image was exceptionally flat prior to calibration and using flats actually caused quite an anti-vignette effect which was not good. I decided to try calibration with bias only, and compared that to no cal at all. I couldn't see a difference so the final image was with no calibration. There was quite a bit of background noise, I could've stretched a bit harder but it just brought out too much noise. I settled on a medium stretch, and pleased enough with the compromise.

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.
