C/2022 E3 (ZTF) is a long-period comet first captured in early March 2022 by the 'Zwicky Transient Facility' (ZTF), a wide-area astronomical observatory at the Palomar Observatory in California, USA.
Taken in the early morning hours of January 28, 2023, this picture was taken in a bright state when the comet approached. By the 24th, the comet was in the shape of an antitail, but now it's gone and looks like a normal comet.
The comet was filmed with a mono camera. The comet had a very fast movement and tail change, so the tail and the coma were separated using a mask as a photoshop program. And then synthesized based on the tail. It's a very hard work.
Currently, the comet will reach its brightest at mag 5.4 around February 2, making it visible to the unaided eye in dark skies.
It will reach its maximum brightness in early February and the comet will gradually become dark away from the sun.

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.
