Crescent and Soap Bubble

[ShineOn]

The Crescent and Soap Bubble nebulae in Cygnus. Many hours of imaging time were spent on this object over the course of multiple nights in May, using my dual imaging rig. Narrowband filters were used to create an HOO base image (minus the stars) and RGB data was used for the stars. The Soap Bubble nebula (bottom right) is a planetary nebula and is so faint it was only discovered in 2007.

Such a tough target this one.  Well done.

That's a vibrant image and the Soap bubble is clear to see.  Lovely job.  I see you are just down the road from me.

I really like the background, and I had hesitated several times in posting a reply, but I'm not sure about the crescent itself.  The fine filamentary structure seems lost, it looks a bit hard and contrasty.  I tend to leave my images less sharpened, so I appreciate this is personal thing.
