At a distance of 25 million light years away, NGC 3184 is about 50,000 light years across. The blue color of its spiral arms comes from a relatively few bright young blue stars. The area between these spiral arms is not devoid of matter, however - the bright stars that highlight the arms were created in huge density waves that circle the nucleus. NGC 3184 is notable for its high abundance of heavy elements, and a supernova (SN 1999gi) that occurred there recently.

Because of clouds I ended up with less than 2 hours of total imaging time - I was unable to get to the Ha filter (time and clouds) ...so those multiple red/pink spots along the blue spiral arms are missing. Clearly, this image is missing data......if we ever see a clear sky again, I plan to more R,G,B and Ha data.

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.
