Comet C/2022 E3 (ZTF) 1-16-2023

Comet ZFT as captured on the morning of January 16, 2023. The processing took an incredibly long time in PixInsight to get rid of the star trails in the comet centered frames. Each sub-frame was batched processed with StarXterminator before integration, taking many hours of PC usage. I would like to go back to these coordinates sometime later and get some better stars to PixelMath back in. As of today, I see Pleiades Astrophoto has released a new update for the CometAlign tool which should speed up and simplify the comet-core centering stacking method of calibrated but unregistered frames, which I hope to try in the near future.

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.
