Revision title: cloudy night reprocess

One night's worth of data taken at the Cherry Springs astronomy field. Lost a few blue subs due to software issues. It was a very hard process due to not having nearly enough data/aperture to work with. Binned 2x2 to attempt to make something out of it.

Title: Cloudy night revision

Description: Played around with some old data on a stint of cloudy nights, not sure if I like it more than my original but it is for sure different. Will not change the fact that I simply just did not have enough original data, I had to aggressively apply noise reduction to keep it presentable.

Title: cloudy night reprocess

Description: it's interesting reprocessing old data and seeing how far my abilities have come. I did not care about the stars at all in this one, I was just curious how much faint gas was actually captured because I was severely lacking time on this target.

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.
