The Great Wall in Cygnus - SHO

This image is my very first narrowband combination and SHO. I've been wanting to have the ability to do this target since the first time I imaged this almost two years ago. The Great Wall in Cygnus is a bright and dynamic region in the greater North America Nebula. It comprises the area where the Mexican peninsula and gulf would be and much of the filed is obscured with a large dust cloud that exists between Earth and the nebula. Interestingly, the stars that irradiate the nebula have yet to be identified though it is theorized that they are likely hidden behind the Wall itself and the great cloud of dust as both of these features look to be illuminated from behind. In fact, the NASA Spitzer Space Telescope was used to image this region in 2011 and it was discovered that many “cocoons” bearing young stellar clusters are hatching throughout the region and are almost entirely hidden in the dust though revealed in infrared (Rebull et al. 2011). The clusters also contain stars in many stages of life, some of which appear to be forming solar discs harboring potential proto-planets. Currrent estimates place the nebula at 1800 light year distance from Earth, a number which can be refined once more stars within the complex are discovered.

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.
