The so-called Great Wall is a part of NGC 7000, the North America Nebula. It is a spectacular HII emission region.

I present it here in the classical Hubble Palette (SHO) as well as the "blue-golden" one with elimination of the green tones, as I couldn't decide on one presentation.
As most detail in this region is in the H-alpha, I decided to shoot that with the RC and shoot the O-III and S-II with the Epsilon. That proved to be quite the challenge because I could not easily register the subs to the higher-resolution RC images with PixInsight. In the end, I generated a huge 155MP artificial star field and registered to that. Preprocessing took longer than image acquisition in this case.

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.
