Butterfly, Crescent, and Bubble

Here is my first go at a bicolor image.  It is the same field as the previous post ... I wanted both the Butterfly and the Crescent nebulas (Cygnus) in the same field.  Oh ... and this time I didn't forget my narrowband filters. Don't give me any grief about not posting this image for 7 months.  Life happens.

I chose to experiment with a more "orange" palette.  I'm sure with some more work I could figure out how to make the OIII regions (notable around the Crescent) more obvious.  Next time.

Butterfly and Crescent and ...

Now if you blow up the part of the image next to the crescent (200%) one can just barely see the Soap Bubble Nebula.   In the red box.  Arrow pointing at it.  I'll give you a moment.

See it?  Faint little guy.  It is notable since it was discovered by a amateur astrophotographer in 2007.  Now that we know where to look anybody can image it though I thought it was pretty neat to pull it out with a lil ol' 200mm Canon lens.
