Crescent Nebula in HOO (NGC6888)

I'm getting used to imaging with an SCT versus a camera lens and I find the learning curve to be considerable. However, I finally feel like I'm learning the nuances of the larger reflector scope. This is the Crescent Nebula taken from my backyard over parts of 4 nights. Although processed mostly in PixInsight, I experimented with using 2 different luminosity layers in Photoshop, one from starless Ha and another from starless OIII. I found that by varying the opacity of each individual layer, I could control the relative intensity of the blue outer Oxygen envelope surrounding the Crescent. Capturing the Oxygen shell was my primary objective when I started this target as this was a struggle in my previous attempt last season. Ironically, I found the most pleasing final version seemed to be where I "dialed down" the blue shell layer quite a bit. Let me know what you think if you have the time.

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.
