Data source: Traveller

On this night I wanted to shoot another subject, but after some minor equipment issues, and more importantly after being completely surrounded by clouds for almost an hour, it was alread too late, and I had very little time to get a proper shot at it.

So I decided to go for the evergreen M31, a very easy subject, showing so much data even with a relatively short total exposure time.

This is the result of 1 hour and 12 minutes of exposures (originally 1:45, some frames were discarded for their poor quality).

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.
Dismissals 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.
