Revision title: Additional Adjustments

Crescent Nebula and Cygnus Environs - July 2022
Televue NP127is - AIS6200MM
A-P 1100 GTO AE, Antlia Pro 3nm NB filters
H,S,O: (3 x 45 x 330s exposures, Bin 2, Gain 200)
R,G,B: (3 x 50 x 90s exposures, Bin 2, Gain 100)
Total Integration Time = 16 hours
This image is more of the massive nebulosity complex within Cygnus. I like this area of the Milky Way because there is so much going on. The background nebulosity is complex, with dark nebulosity appearing as "ink spills" over star blown shock fronts of hydrogen.
In the foreground is the NGC6888, the Crescent Nebula. It is formed by the Wolf Rayet Star at its centre (WR-136) light up and pushing around material ejected from the star earlier in its life. Wolf Rayet stars are very interesting, have lost or spent most of their hydrogen, and now powered mainly by Helium fusion. The nebula is 5000 l-y away, and about 25 l-y across.
Also visible at centre bottom of the frame, is the "Soup Bubble" Nebula, a very interesting object recently discovered (2007/08) by an amateur astronomer, Dave Jurasevich. This object only appears when using a Ha filter.
I tried to strike a decent balance between the Crescent Nebula and the background nebulosity in this composition. Narrowband data was used to the show the nebulosity, while RGB filters were used only for the stars and star colours.

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.
