Sh2-2 Sparpless2 2 HII region

Sharpless2-2 is the lowest target I have ever imaged, transiting by observatory in Taos, NM at 15 degrees. So these subs were collected at elevations of 13 to 15 degrees, rather low, but we do see some stars and Ha nebulosity. Frankly I find it rather dull, but there is a nice cluster of blue stars near the center designated NGC 6281. The size of Sh2-2 is only 1 degree, so it is the central part of this image which is 1.6 degrees.

Wikipedia:

Sh 2-2, also known as Sharpless 2, is an emission nebula in the constellation of Scorpius. It appears as a mid-range brightness making it difficult to view. It is believed to currently host an X-ray binary star that originated and was ejected from the Scorpius OB1 association.

The nebulous area is fairly large with an irregular shape appearing as a H II region.[2] The remnant has an apparent diameter that covers approximately 60'

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.
