There's OIII in them thar nebulae!

After struggling for a year to bring out the OIII signal in my L-eXtreme images, PixInsight and @Bill Blanshan's HOO normalization script seems to have done the trick. I blended the result of Bill's script with my default reddish nebula to find a happy medium. I have a LOT left to learn here, but I'd never post anything if I waited until I felt I'd really gotten a grip on every process in PixInsight. This will have to do for now - and for the most part, I'm happy.

In addition to the new PI processing, this NGC 281 builds on last year's with the addition of just shy of 3 hours of extra data with the L-eXtreme filter along with an hour of RGB stars.

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.
