M101 Pin Wheel Galaxy

This image of M101, the Pinwheel Galaxy, was taken at the Rockhound State Park which is about 10 miles east of Deming, New Mexico. Sky conditions were less than ideal as I was competing with a near full moon. After careful processing to try to eliminate the moon glow without sacraficing too much image detail, I was fairly happy with the end result. I do have an Optron L Enhance filter but for some reason forgot to add it to the imaging train. It's always something. If you don't zoom in too much, a lot of detail does show up in the dust lanes. I like the color that the Photometric color calibration in Pixnsight produce. Wikepedia states that this galaxy contains about 3 trillion stars, about twice the stars of our own Milky Way. The central core of M101 comes in at an impressive 3 billion solar masses. Overall, not a bad result. As always, comments and criticism are welcomed and encouraged.

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.
