Dark Nebulae

Dark nebulae are clouds of cold gas and dust which only reveal themselves by blocking out the light of  more distant stars. Consequently, most of them are to be found in the plane of the Milky Way where stars are most densely packed. The astronomer Edward Barnard catalogued many of them from photographic plates and they are now known by their ‘B’ number.

This image shows B142 & B143, just to the west of ? Aquilae or Tarazed.

As I wasn’t too sure of the exact position of the nebulae I positioned Tarazed at the left hand side of the field and took 11 3 minute exposures which were then combined for the final image. Telescope was the ZS70.
