C/2019 Y4 (ATLAS) - 10. April 2020

Comet C/2010 Y4 at April 10, 2020 from my backyard.

Okay, i f***cked it up.

During comet alignment, i thought the comet must have changed his trajectory over the session. So i aligned each color channel separately, which resulted in lateral offsets between the channels in the comet stacks. I realigned them manually as good as i could. But the remaining misalignment - together with the moon which showed up during the session - causes color artifacts, still visible in the final image.

Later i found, i additionally opened subs from pre-registration, they caused the "curve". But i was too lazy to start over from the beginning.

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.
