are 'voids' obscuring all kinds of objects in the cosmos. Voids may be
within an object, or between an object and us. Dark Nebulae, Dark Lanes,
and Dust Lanes looks out into the deep sky at those apparent dark
regions in space, which are among the most compelling telescopic
destinations for amateur observers. One famous example is Barnard's dark
nebulae - those striking dark clouds set against the background of
stars in the Milky Way. But there are countless other less well known
examples.
