Cygnus Wall South

In the constellation, Cygnus, is a ridge of dust and glowing gas called Cygnus Wall. It is an active star-forming region that stretches along a ocean of blue, glowing oxygen gas. The golden color is glowing sulfur and hydrogen gas. This image shows the layered southern end of the wall.​
 
This project was long in the planning and the execution. I collected most of the exposures I needed for this image using two different telescopes and two different cameras at my home observatory in 2019. It was not until the end of 2024, however, that I gained access to a large telescope located in Spain that I used to acquire the exposures needed to create the structural detail of this remarkable nebula. 
 
28 total hours exposure of RGB visible light, plus hydrogen, oxygen & sulfur emissions
