Data acquired through custom advanced requests at Telescope Live using my own credits so this specific data is unique to me.

I started acquiring this data in early December of 2021, but weather and scheduling conflicts had delayed its completion. At the time I started there were few examples of this image but since then ChileScope had done a processing challenge on this target going deeper than I had and had resulted in many images of this region getting posted.

This area of the sky is full of satellites crossings. The bright trails were not difficult for normal pixel rejection to process out but in the color data with the fewer subs the faint trails posed a problem. I ended up using Adam Block's selective pixel rejection technique to take care of those.

For the color stars, I used Team Noctua's MMMTFStars custom script provided to me by my friend Chen Wu which progressively stretches the stars with HT and creates a star mask to blend back into a starless stretched RGB image.

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.
