Target Description:
Comet Pons-Brooks is a periodic comet 12/Pons-Brooks reached perihelion on April 21, 19 days after this image was taken. I discarded some of the subframes (4) because they showed an enlarged nucleus. They may have captured a real outburst, but did not fit with the other subs to make a coherent "single still image." This comet is known to produce such flare-ups of much greater brightness than the observed effect/event captured in those few subs.

This comet's orbital period is about 71 years, so some of the youngsters among us may see the next time it comes to the inner solar system and some of the oldsters may have seen it the last time it was here.

Processing Description:
Largely following the workflow here. But comets be hard! In this data set, which apparently was not taken under completely dark skies, gradients were strong, colored, and varied from sub to sub. The posted image shows brown 'clouds' in the background. I harbor doubts that those are real. However, if the background were dropped to remove all of those, some of the comet would go with them. So, there they are, whatever they are.

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.
