Learning to Process Comets - C/2022 E3 (ZTF)

I’m a little late to the main attraction here, but I learned a ton about comet capture and processing in this exercise.

“The Green Comet” has fallen out of favor of many astronomers now that it is fading in its path away from Earth. I am always mesmerized by people’s image captures of comets and consider these imagers practically magicians. Many people don’t realize how much more complicated capturing and processing comets are compared to the complexity of deep space or other solar system objects. With respect to the star field around the comet, the comet moves MUCH faster than those stars. This presents a few problems. If during capture, your exposure goes too long you will get a streaky comet core. This should be avoided. If you process your captured frames by aligning on the stars, you will also get a streaky comet. If you process your captures by aligning on the comet - you will get a streaky star field. I have never successfully captured and processed a faster moving comet before, and it took me a few tries to get through this to this result.

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.
