IC 59 and IC 63 are two comet shaped nebulae near the bright star Gamma Cassiopeiae (γ Cas, γ Cassiopeiae), which is the energy source of their illumination. Being closer to the star, IC 63 shows more brightening of its front edge and stronger H-II emission. IC 59 is situated further away from the star and has lower level of HII emission, which makes its reflection component to appear more prominent. VdB 5 is the blue reflection nebula surrounding the star Navi (γ Cas, see mouseover). The proximiy of the 2.15 mag. star makes the imaging of the nebula tricky.
