The Great Sagittarius Star Cloud
The largest star cloud in the earthly observable universe lies just below Messier 8 in Sagittarius. Under dark skies it can cast faint shadows and can be seen reflected on bodies of water. As far as deep sky objects go, it is the brightest!
The Great Star Cloud in Sagittarius is festooned with knots and cavities of dark nebulae with a countless number of individual stars.
This view comes via a 45 minute exposure on Acros 100 film with the combination of a Pentax 67 and the 400mm F/4 SMC Takumar lens.
This frame is part of an ongoing series of long exposures on traditional materials dedicated to the work of Edward Emerson Barnard, the father of Milky Way photography.
