12P/Pons-Brooks Comet - OSC

I ignored this comet thinking it was not visible from my backyard. I finally discovered I had a view of it in the western sky between the trees and gave it a try. I got about 45 minutes of 2 minute exposures between 10 and 15 degrees above the horizon and into the city sky glow. The subs had terrible gradients which I more or less dealt with.

Processing steps were:

1. Used WBPP to make a master aligned on the stars and showing a blurred comet.
2. Ran StarXterminator to get stars only master with no comet.
3. Ran calibrated, debayered and registered subs through StarXterminator in batch mode with a mask protecting the comet. This produced unaligned comet only images.
4. Ran PI Comet Alignment on the comet only subs.
5. Integrated the aligned comet only images to get a comet master.
6. Moved to PS to further process both the stars and comet and merged them using layers in PS.

Not perfect but here it is.

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.
