NGC 6914 is captured with a small aperture and a few hours of exposure time in Bortle 4 and already we can clearly see, after Image processing, many of the subtle intricacies coming from the scattered and absorbed light by the dust around the supermassive and hot stars of the galaxy. NGC 6914 is surrounded by an intense H- alfa signal captured with a narrow band filter.
I had an issue with a new off-axis guider protruding on the chip and I had to crop a little the frame.
The best description to my knowledge of this complex can be found here:
https://pixinsight.com/gallery/NGC6914-CAHA/index.htmlThe nebular complex know as NGC 6914, comprising in the Cygnus constellation, is a clear case of combination of the three types of nebulae described above. This region concentrates gaseous and dusty masses of the galactic plane, where stars are born. Fragments of nebula situated between the Earth and the young stars appear to be dark, with varying opacities and intricate shapes. In other areas, near the younger and hotter stars, dust shines with the bluish colors of the reflection nebulas. Lastly, all the image is covered by ionized hydrogen that gives to the scene a reddish and warm backdrop. Newly born stars, which are only a few million years old, mill around the scene. Their colors reveal their diversity of masses and temperatures. But in this small portion of the Galaxy, about 6,000 light-years away, massive and hot stars (O and B type stars) are so abundant that the area is classified as an OB association. Its name is Cygnus OB2.
