There 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.
