Sharpless 2-103, a portion of the Veil Nebula Complex

Sharpless 2-103 is an emission nebula that is part of eastern arc of the veil nebula (NGC 6992), one of the largest and well known supernova remnants in the northern sky. I couldn't find much information on Sharpless 2-103 but the field of view seems to share the same neighborhood with NGC 6995, which, according to Bob King's article in Sky & Telescope, "Explore the Veil Nebula", is the bright arc of material at the south end of NGC 6992 that unfurls to the west. The article also notes that the nebula continues to expand outward since the supernova that created it thousands of years ago. Photos taken with the Hubble Space Telescope in 1997 compared with those from 2015 show individual filaments on the move.

What captures my interest most in this image are the clearly defined filaments formed by dense concentrations of glowing Oxygen III (blue/green) created by the shock wave long ago . By contrast, the ionized Hydrogen (red) in this region is more diffuse and less well defined.

This image was created by mapping HOO narrowband images to RGB in Pixinsight. The data was taken through an RH-305 astrograph and FLI 8300 series camera at Deep Sky West.

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.
