* There is no definitive distance data available for this object, and the figure of three hundred light years given here is based on estimated distances to similar structures in the region, notably the Cygnus Rift. If the Dark Lane is signicantly closer, or farther away, this will necessarily affect the estimated length of the lane, given above as some fifty light years.
