NGC6960; aka West Veil nebula in Cygnus (RGB)

NGC 6960, also known as the Western Veil Nebula, the Witch's Broom Nebula, and Sharpless 103, is the remnant from a supernova which occurred about 10,000 years ago. It is the counterpart to the Eastern Veil Nebula, NGC 6992. Its amazing filamentary structure is thought to be due to compression of expanding shells of gas as they meet the resistance of the interstellar medium. However, the shells are so thin that, with few exceptions, we see them only where viewed exactly edge-on. The fact that much of what we see as "empty" space is filled with dark dust is evidenced by the fact that more background stars are visible below the nebula than above it. This is because the shock wave has swept the area below the nebula clear of the dust, allowing more background stars to shine through. The bright star, 52 Cygni, is a type K star and is actually a foreground object with no physically association with the nebula. (Sky & Telescope; March 9, 2014) This image was created by combining 2 Hrs (24 x 300secs) of Red data plus 2 Hrs each of Blue and Green data, acquired from a test data download from Roboscopes Pier-7 in Spain: William Optics FLT132 on a Paramount with a ZW) CMOS camera (294MM Pro). This acquisition was unguided, as the subs were only 300secs long, the max. for this setup. I used Pixinsight to stack each set separately using their provided 10 x (Darks, Flats, and Bias) Calibration frames, and then combined the three sets using the Channel Combination tool. All the pre and post processing in Pixinsight, with final touches in Paintshop Pro for clarity, vibrancy, and white balance temps. Hope you guys like this version as much as I enjoyed working on it for almost 12 hours (off and on).

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.
