Cygnus Wall in NGC 7000

This is my image of the portion of the North America Nebula (NGC 7000) known as the Cygnus Wall. I could not fit the entire North America Nebula in my telescope's field of view because it is huge, more than 10 times the size of the full moon. It resides 2,590 light-years away in the constellation Cygnus, the Swan, within the Summer Triangle of bright stars Deneb, Altair, and Vega. The disk of the Milky Way passes right through the Summer Triangle and contains many emission nebulae like NGC 7000 captured in this image. The beautiful red color is from ionized hydrogen (H II). And the Cygnus Wall is a particularly active H II region where lots of new stars are being formed. These young, massive stars pump out ionizing photons which cause the hydrogen gas to emit a red color at the Hα wavelength. The wall is about 20 light-years across and provides a vivid contrast between the ionized hydrogen and dark dust lanes. A huge band of dust known as L935 separates the North America Nebula from the Pelican Nebula which will be the subject of my next image.

I made this image from the best of over thirty 300-second exposures shot at 1630mm focal length, calibrated with 20 each dark, flat, and dark flat frames. I used my Baader dual-bandpass filter (Hα and OIII) to help battle light pollution and smoke. And I employed Astro Pixel Processor for stacking and stretching to pull out more detail in the final image followed by post-processing with StarNet++, Photoshop, and DeNoise AI.

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.
