NGC6914 in Cygnus
with 10" f/3.9 Astrograph
Uploaded 10/10/20

 
This
            amazing region is centered on a stunning blue reflection nebulosity
            with much dark lane details. The entire field is awash with red
            Hydrogen Alpha nebulosity as well, creating a contrasting scene
            of blue vs red. Add to that the brilliant Cygnus starfield near
            Deneb and you have the perfect target. It is however very dim
            and required long exposures to render properly. 90 minutes of
            standard RGB data was supplemented with an additional 120 minutes
            of OIII and Halpha exposures to form this complete image.
