Next to the well known targets, the constellation Cygnus hosts many more or less structured areas of ionized gases, the so called H-II regions.

New stars are born in these areas of the universe. Their bright ultraviolet radiation ionise the surrounding molecules which can be observed as a faint glow.

Typically these regions are imaged using an H-Alpha filter. A decent exposure time reveals its finer structure:

For me the unexpected large amount of oxygen was more appealing, so I spent some extra exposure time into this filter. Most of the bright haze in my edit originates from this light.

Nevertheless there are some more quite interesting objects to discover which qualify to be imaged with a larger focal length. One prominent example is the bright reflection nebula NGC6914, surrounded by several dark nebulae.

In the bottom right you'll find LBN278, the Propeller Nebula. My edit washes out some details, check out the H-Alpha image above where it is clearly recognizable:

And finally here is the annotated version of this image:
