Barnard 145 is a dark nebula not far from NGC 6888 in Cygnus. It is seen against the general nebulosity of this region of Cygnus so, therefore, must be closer but I didn't find any distance estimate for it. I couldn't even find a good estimate for the background nebulosity. Those ranged from 1,500 to over 5,000 light-years. Some of the nebulosity seems related to the dark nebula at the eastern (left) end or is in front of the dark cloud.
