This target was a challenge. I've been spoiled shooting narrowband, which mostly neutralizes the Bay Area's light pollution. Broadband targets like galaxies aren't too bad, as they're typically fairly bright and you have a lot of background you can use to neutralize the light pollution. Targets like this with a bunch of nebulosity everywhere makes it tricky to deal with the gradients. I found PI's NormalizeScaleGradient helpful by adjusting the various subs to my best sub's gradient. Even still, trying to bring out dark nebula structure is a real pain. I think you need dark skies to really do these kinds of targets justice. I wasn't having much luck bringing out the emission nebula to the right, so I finally broke down and grabbed some Ha to blend in.

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.
