27 Cyg region

Not much to say other than I pointed the scope at 27 Cyg and took a bunch of subs. If I had planned more, I might have included the Tulip or other, but such as it is. Nebulosity visible in this OSC image is very broadly dispersed, though uneven as you can see. Other than the diffuse and denser red emission nebula, some of the denser foreground dust clouds result in dark nebular clouds and strands. There is also some very diffuse blue reflection nebula and one, more defined blue arc of reflection nebulosity in the upper right corner that I assume is lit by the trio of hot blue stars to its right. There is a lot of dark mottling in the darker regions in the upper and left part of this image. While I believe this is artifact, it is not your normal noise. I believe it is caused by the method I used to remove the stars...

Processing was the most difficult that I have encountered in my year of playing around with this stuff. I need to start looking for subjects that are not embedded in these extreme starfields! Several star reduction methods were applied or used to no avail. So I tried other stuff...

I present two renditions, the final version that is less stretched than the first and darker. To me, it reduces the "presence" and distraction that the broad reflection light causes. I can't really state which is my favorite though, but I figure bright is happier than dark (aka Bob Ross). Once again, it is cloudy in Cascade Land, so I am putting the darker version as the final version.

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.
