SH2-112 CED 181 LBN 337 Nebula in Cygnus

Sharpless 2-112 is a diffuse emission nebula in Cygnus, located on the surface of a huge sphere of cold, molecular hydrogen, it lies about 5.600 light years from Earth. It does not appear far from the North America Nebula, but is twice as far away from Earth. This whole area of Cygnus is dominated by the Milky Way and is awash in faint nebulosity. The nebula is illuminated by BD+45 3216, the bright star at its centre, which is about 30x the size of the Sun, and radiates strongly in ultra-violet.

It is a fairly bright beautiful nebula easily available in the Northern sky. The weather was clear with average transparency but less than average seeing. Cloudy weather forecast for the next couple of weeks so this looked like as good as it will get for awhile. Good Ha with much less O3. I took a brief sequence of RGB data before shutting down. The image is HOO with RGB.

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.
