Comet C/2022 E3 (ZTF)
This long period visitor from the Oort cloud was discovered on March 2nd last year at the Palomar Observatory near San Diego by the Zwicky Transient Facility (ZTF). I stayed up way past my bedtime last Friday to grab these frames because some passing clouds ruined my first imaging run and the clouds didn’t clear until about 3am. Last time this comet visited us was 50,000 years ago and depending on how this close approach to the sun goes, it’s either going to be ejected from the solar system permanently or at least not come back for several million years. I made a lot of mistakes on this one. I framed it too far to the bottom left of the chip anticipating it would move more than it did. I also should have taken at least an hour of Lum instead of just 15 mins. I really should have rotated my camera 90° but after having the first run spoiled by nearly solid clouds, I was tired and that would have added more time to check my polar alignment and redo my guiding calibration and I just wasn't that interested in staying up any longer. I promise to do better on the next one.

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.
