Comet C/2022 E3 (ZTF)

Interesting project! My first use of a "comet" program. I used the one on "Deep Sky Stacker" because it looked more user friendly. Picked exposure times on the long side and tended to get more light pollution noise from the overexposures. Hopefully the weather gods will smile on me so I can take another shot at it before it leaves us. The city streetlight didn't help either.

A rare green comet is about to make its closest pass by Earth. The comet, called C/2022 E3, spends most of its time on the outermost edges of the solar system, in the Oort cloud, but it will make its closest pass by Earth on 2 February.

The close pass will bring the comet within about 45 million kilometers of Earth, about 120 times the distance between Earth and the moon or about one-fifth the average distance to Mars. It only orbits the sun once every 50,000 years or so, so its last pass by our home planet was in the Stone Age, when humans still coexisted with Neanderthals. .... New Scientist (internet)

Other articles indicate that the orbit time is highly unpredictable, and estimates vary from 50,000 years to a million or possibly could leave the solar system completely.

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.
