Take your binoculars in a dark summer night and watch for the brightest
star in the constellation of Aquila: Atair (also called Altair).
At the same time you will see gamma Aquilae about two degrees into
north-west direction and myriads of fainter stars right in between the
rich summer milky way. Just 1.5 degrees west you might remark small regions
with considerable less stars. These are the dark nebulae Barnard 142/143,
also called the E-nebula or triple cave nebula due to its shape.
There are no holes in the starry sky but interstellar dust clouds
which block light from the stars behind.
