"Piercing the Sky" — C/2022 E3 (ZTF)

Revision title: REDUX

Here it is, darting through the cosmos. I was lucky enough to get a 2 hour break in the clouds on the morning of January 22. Spun off some L exposures then RGB an hour after.

Processing was a big challenge, especially being shot mono. Thanks to some @Adam Block & @Russell Croman magic, I was able to pull off something I'm pleased with. I tried to summarize the workflow below. See you in 50,000 years!

Processing workflow:

*Mono

COMET:

Calibrate and register images (on stars)
CometAlignment on registered images
Batch StarXTerminator on comet aligned images
ImageIntegration starless comet images
*Repeat on all filters if necessary
*CometAlignment again on all comet stacks
Processing as usual

STARS:

*Combine registered RGB images
DBE/ABE, PCC/SPCC
StarXTerminator and keep only star image

COMBINATION:
Combine fully processed (and stretched) starless comet and star image:

Pixinsight: Pixelmath "~((~starless)*(~stars));"
Photoshop: Star image on top using "Screen" Blend Mode

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.
