NGC 3184 (The Little Pinwheel Galaxy)

The Little P pinwheel is located in the constellation Ursa Major. Although its magnitude is 9.6, it is difficult to distinguish its structure. Its visual diameter ionly 7 minutes. It contains two HII regions, called NGC 3180 and NGC 3181. It has contained several supernovae. Its spiral arms have a beautiful blue color due to bright young stars, not very numerous. I have tried to respect this color. For this, the Ha shots have participated above all in the luminance, and to a lesser degree in the color using a high contrast Ha master. I wanted the galaxy to be the absolute protagonist of the photograph and I programmed a long total exposure. Despite this, it was difficult to obtain details. The total initial exposure time was 23 hours and 52 min, but I was very demanding in the selection, and finally used 14 h and 39 min of shots in L, R, G, B and Ha.

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.
