Here it is, just at the end.I knew that in the right place I could get something better than what I had done so far.So on September 8th I found a site clear of a few tenths of a degree on the horizon, in the wide bed of a river.Unfortunately this time the targeting was too precise on the comet's nucleus. And I sacrificed part of the comet's tail for very precious minutes of integration. The first shot (discarded) was acquired at 4.52 am (nine minutes after sunrise) with the comet at about 3° above the horizon; the last one at 5.42 with the comet at approximately 11°. on the horizon. I acquired 23 120" frames, and I integrated 15 of them, from 4.55 to 5.28 with the comet from 3.3 to 8.3 degrees. In short, a stroke of luck. With these numbers, which are decreasing, in the next few days and up to the 12th -13 I think that only instrumental observational activity remains; on the 15th the comet will rise with the sun, just a few degrees from our star.In the elaboration I referred to Adam Block's cometary processes, even if some peculiarities of the comet forced me to make some customizations.

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.
