CYGNUS WALL IN HUBBLE PALETTE

The Cygnus Wall, also known as the Swan Wall or the Gulf of Mexico, is a region of ionized gas that is part of the larger region cataloged as NGC7000 or the North America Nebula.NGC7000 is an emission nebula of the Cygnus constellation, whose shape resembles the continent of North America.
1960 light years away, it was discovered by William Herschel and can only be observed with long exposure photos or with telescopes with a generous aperture but at low magnification (under dark skies).
The North America Nebula and the nearby Pelican Nebula are part of the same giant interstellar cloud that spans most of the constellation. In the photo there is also the dark nebula LDN 935 that separates North America from the pelican.
This image was obtained by integrating and processing according to the Hubble Palette technique. In fact, in the photo the hydrogen, sulfur and oxygen gases are clearly visible and contrasted, which would not be so well discriminated with other techniques.
Image obtained by me and Michele Russo.

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.
