This field appeals to astrophotographers because it combines red emission and blue reflection nebulae, with a challenging ~9-mag brightness gap between the bright star and the faint clouds. IC 63 and IC 59 are part of a larger nebulous complex around γ Cas spanning roughly 2°—about four full Moons wide.
