Soul nebula - HOO

I had two nights the other days and so bad were the conditions, I could barely see Cassiopeia. The first night when I took the Ha was the better of the two, but the OIII night really was tough - I think there was some sea mist floating around, but even so I made the best of it, in hope. I took 103 Has and 95 OIIIs at 4 minutes exposure time, each. For the first time I have somehow managed to get some noticeable blue out of the OIII, which considering the quality of the OIII data because of the conditions seems counterintuitive to me. I did not change my processing technique in any particular way either, so I am not sure why that happened, but I am not complaining! Imaging time was 13 hours and 12 minutes. I also present a starless version. 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.
