SH2_114 Flying Dragon Nebula

Revision title: Final:-) I'm done.

Sh2-114 in Cygnus is a very faint emission nebula in the Milky Way, known as the Flying Dragon Nebula.
For me, this has been a study in exposure times and the relative merits of longer vs shorter exposures. This image includes (so far) 13 hours, 30 minutes of total exposure time. It includes 6 minuet, 8 minute, 10 minute and a few 12 minutes exposures. Due to its faintness, I favored longer exposures (dominantly 8 minutes) but have discovered that longer exposure times can also contribute unwanted elements to the image, so going forward will likely add 5 or even 4 minute exposures. I believe this will result in a cleaner image with less superfluous "stuff".
Thanks to Tim for leading me to this gem. https://www.astrobin.com/users/Telperion_Stars/

Title: Reduced noise, using NoiseX

Description: Original had a good bit of noise. I had previously run NoiseX while using a mask to protect the Dragon, but since have discovered that the Dragon did not need protection, and benefited from NoiseX. Still looking to get a few more hours, so hopefully this image will continue to improve.

Description: Added 1 hour 45 minutes of 5 minute exposures. Interestingly it helped fill in the head of the dragon. Seems unlikely, but more likely a difference in my post processing?

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.
