22 Nov-2021, org. comet image now restored, thanks a lot :-)
https://astrob.in/361061/0/

This Comet image was manually uploaded again 18. Oct-2020, due to it was not re-stored from the AB Febr-2020 crash.

The image consist of the following stacks,

Aligned on stars and on the comet head (median stack), the color stack, 73x120sec.

Aligned on stars, 2x32x30sec and 268x30 sec lum frames.

Aligned on the comet head(median stacks), 16x60sec and 2x32x30ses and 92x30sec.

It's an earlier AB IOTD image that I uploaded from my PC HDD today.

I was triggered to do this effort because Mr. Salvatore was able to restore a major part of my earlier uploaded AB images, as mentioned on/in the AB Forum today :-)

Please check my Comet image process, it's shown here, in a pdf file, thanks,

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.
