Veils of Oxygen

Two nights under almost-full Moon, O3 narrowband filters and Stille's awesome processing skills can breathe oxygen into the stunning Cygnus Supernova Remnant (Sh108 or Veil Nebulae).

Framing this large object has been challenging, even when combining a fast triplet and full-frame sensor; as such, I could not fit the whole loop, but I hope I have captured the most interesting parts.

In post-processing, false-color mimicking the 500.7 nm doubly-ionized oxygen band has been applied to the nebular parts of the image using delicate star masking procedures, making this image more artistically-pleasing, but still scientifically-pertinent if one ignores the color channels.

Before the Cygnus Loop dips under the winter horizon, I'll attempt to complete the spectra of this image with wider band data, but in the meantime I hope you enjoy this 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.
