NGC3184 Little Pinwheel Galaxy in HaRGB

NGC 3184, the Little Pinwheel Galaxy, is a spiral galaxy approximately 40 million light-years away in the constellation Ursa Major. Its name comes from its resemblance to the Pinwheel Galaxy M101. Its numerous Hii regions, here captured with an Ha filter, are so prominent that have been assigned individual denominations NGC3184-xxx. One specially visible (the one at 10:00 hrs to the center in our picture) has its own name NGC3181.
While talking about classifications, Simbad seems to use the two entries NCG3180 and NGC3184 interchangeably for the whole galaxy.

NGC 3184 housed recently several supernovae and, in 2010, what appeared to be a supernova, but was later recognized to be in reality the outburst of a variable star (but: what an outburst!!!)

The nearby star mu-UMa, just outside the field, created bad reflections in my optics, and that required some additional precautions both during recording and while processing to keep them at bay.
I discarded a good three hours of signal captured with L-Pro filter as its quality was worse than the one obtained with the clear filter, which is published here.

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.
