SH 2-13 Emission Nebula (GUM 68 / RCW 133) in Narrowband SHO

Shot this target last night while waiting for my main one to rise. Sharpless 2-13 or RCW 133/Gum 68 is an emission nebula sandwiched between the open cluster M6 and the War and Peace nebula NGC6357 in the constellation Scorpius and lying about 5.540 light-years away from Earth. The nebula is a hydrogen and sulphur rich region that surrounds the O9.5V binary star HD158186 which also lies close to the small cluster Antalova 1 where some oxygen emissions exist.

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.
