M101 "Pinwheel" Galaxy with Supernova SN 2023ixf

More out of pure luck than anything, I was imaging M101 for two nights just after supernova SN 2023ixf was detected. With little more than 3 hours to add to my 10 hours from 2021 and 2022, this was a tough image to pull more detail out of. Luminance, yes - and it was much quicker to process and involved fewer masks & freehand adjustments, but for some reason NGC5474 (my favourite dwarf galaxy ever) has more detail in my 2022 M101 image. I processed this TWICE to see if I could pull out the faint stars visible in my 2022 shot but no dice.

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.
