Less than 500 light-years away and blocking light from more distant, background stars in the Milky Way, the densest part of the dust cloud of Caldwell 68 is about 8 light-years long. At its tip is a group of reflection nebulae cataloged as NGC 6726, 6727, 6729, and IC 4812. A characteristic blue color is produced as light from hot stars is reflected by the cosmic dust.
