Captured the viral comet of 2023 from my rooftop when moon was at 87% full with my broadband filter L-Pro and my OSC camera! First attempt on a comet both on acquisiton and processing.I had to deal with the moon and LP, but could not wait for another 50.000 years or so!
Integration total time of about 130 frames * 60sec each, 2+ hours or so.

Pre&Post processing at PI.

Pre: WBPP up tp registering& integration of frames, StarXT on final integration to extract stars background. Comet allignmet on all frames and integrating as a separate integration for the comet only.

Post: DBE/PCC/NoiseXT on both integration and a LOT of iteration for DBE and NoiseXT for comet image, because comet integration let many trailing artifacts without rejecting them. Some curves after HT and combining Starless comet with stars for the final image. By far the most difficult workflow I had to deal with.

Not fully satisfied but it is an acceptable result I think...

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.
