Revision title: OIII revision

I shot this over three relatively clear nights in the late fall of 2023. I found the framing on my ED127 to be pretty well perfect for this particular target. It was one of the more faint targets I've ever attempted, and thus required a significant increase in integration over most other targets. OIII as usual was the noisiest and most faint and was the most challenging to work with in processing. I may go back to add more data on this target, likely just within OIII. A 2024 revision helped to bring out more OIII detail, but it remains limited and noisy.

Title: OIII revision

Description: Just a quick revision trying to draw out more of the OIII that was present in my data. It is certainly more faint than SII (and much more so than Ha), but there was more to bring out. I also used the new BX (2.0) which had a marked improvement on my stars, particularly in the bottom two corners.

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.
