Emission nebula in Cygnus
Uploaded 10/24/24

 
Surrounding
            the hot supergiant 68 Cygni, this dim emission nebula in Cygnus
            is so faint, it was hardly recorded at all in the RGB data. It
            was only with the addition of an extra hour with the IDAS NBZ-II
            filter that its true extent could be seen. The entire field is
            filled with structured emission, with linear streaks across its
            entirety. As an added bonus, gorgeous dark Bok globules splash
            across its southern end. An incredible field for sure!
