The Mushroom Cloud of Cygnus

I am not exactly sure what to call this. The focus for me is on the dark nebula so the Mushroom Cloud seemed right. But maybe the Dirty Pond or the Thunderstorm?

Of course this is the North America Nebula and the Pelican, but my goal was for it not to appear as the traditional continental outline. Instead I wanted to bring out detail to the "oceans" areas. And then there is that third bright emission area that balances the Pelican and Wall. That surprised me.

This is all backyard data from the city of Portland Oregon. At latitude 45 North, Cygnus is well placed for my peak-a-boo sky view. The FOV is not cropped much from the original QHY600M+FSQ106 data.

I mixed the SHO color channels in PI's Pixelmath. I just kept trying different combo's till something clicked. I failed to note the final but it was a variant on SHO. Color was further adjusted in PS.

Starnet++ was used to identify the star locations and PS content aware fill used to replace them. After high pass and unsharp mask filters, stars were added back.

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.
