I already posted the Hα data of this region previously:
https://www.focalworld.com/threads/maybe-the-start-of-something-good.16843/
Here is the final version of that image. More data in the pipeline for a couple of other targets but processing of those will have to wait until back from an upcoming trip.
This region of the sky, in the approximate middle of the constellation Cygnus, is brimming with clouds of ionized hydrogen. In this image I have located the bright star Sadr just out of the field of view to the lower right, and highlighted a butterfly shaped section of the nebula. But truthfully, it is hard to point to this section of the sky without getting some interesting and captivating shapes in your field of view.
This was imaged in RGB and Hα, with the Hα mixed in to the red channel to add some sharpness and detail. In retrospect, I might have also captured OIII and made a 'proper' bi-color narrowband image out of this as well.
Comments and critiques most welcome!

Here is some more detail from Wikipedia:
The Sadr Region (also known as IC 1318 or the Gamma Cygni Nebula) is the diffuse emission nebula surrounding Sadr (γ Cygni) at the center of Cygnus's cross. The Sadr Region is one of the surrounding nebulous regions; others include the Butterfly Nebula and the Crescent Nebula. It contains many dark nebulae in addition to the emission diffuse nebulae.
Sadr itself has approximately a magnitude of 2.2. The nebulous regions around the region are also fairly bright.
