Ghostly clouds of gas and dust in Cassiopeia
Ghostly interstellar clouds known as IC 59 and IC 63 in the constellation Cassiopeia in the light of hydrogen taken from suburban Bloomington, Indiana. This is a fairly challenging astrophotography target because it's faint and dusty; much of the light is reflection from the bright star Gamma Cas at lower right (the pillar in IC 63 at bottom points toward it), which is largely blocked by the narrow-band filter.
