This is an image of Comet 12P/Pons-Brooks . What an interesting comet!
I continue to develop new techniques for comet processing. Less than 90 minutes of time (and even some of that was questionable in the twilight) were available. The brief windows of opportunity for comets is typical since they are usually near the Sun (low in the sky once dark) when at their best. So optimizing the time is critical. The method I used here was to use comet-tracked data! This means stars are streaked in the raw data. What might interest comet-processors is that I did not take extra data of the star field!

Comet tracked data relieves the limitations of exposure time due to the motion of the comet. Again, the motion of comets in the inner solar system (or near the Earth) is usually high when they are at their best. So the best S/N is usually achieved by comet-tracked exposures. The previous image of Comet Lemmon was the first experiment in this direction. This image takes the ideas one step farther. I will have a video on the technique soon. Pons-Brooks wasn't really moving fast enough to make this a compelling example. So I need to get another...

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.
