Cone nebula and surrounds - Rasa 8 - HOO - duo filter

I took this at the end of the better weather-cycle we have just had, and it was on a night when the clarity of the sky was very poor, with high level murkiness. I could barely see Orion's belt and hardly a thing of Leo, and I almost gave up. However, somehow I managed to get enough decent subs to obtain something, although on a better night they would have been regarded as too poor and binned - beggars cannot be choosers, as they say.

I was not quite sure what I wanted to achieve out of the data, as far as the palette was concerned. It was a bit of a fiddle to get the colour right. The data gives plenty of O3 in the immediate vicinity just above the cone itself, but there is a subtle O3 that slightly extends beyond there, which I wanted to bring forth in the picture. That said, if you go too far, then the depth of the red and other hues in the rest of the picture, alters further than I wanted. I include here two versions and their starless counterparts, hoping I have got things just about right. Thanks everyone...

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.
