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...
