Barnard 289 - Dark Nebula in Sagittarius - 27/6/2014 (Processed stack)
At the end of a good night starting to reach dew-point, I decided to try a short sequence on a different style of object. Having liked some of the dark details in dust lanes in the area around Messier's M7 in nearby Scorpius, I thought I'd try a Barnard Dark Nebula Catalogue object in Sagittarius, close to the heart of he Milky Way galaxy where stars abound and foreground dark nebula show themselves. B289 is the darkest area at the centre of this image.
