Gamma Sygni Nebula is a big nebula. The posted image is its central part. Efforts has been placed in revealing the dark part of the nebulosity. Taken at DSW.

Version B further enhances the dark part. Isn't it overdone? Any comments are welcome! -- It is overdone, and was deleted. To enhance the dark details needs more work.
