Only this Ic63 nebula, without the Gamma Cassiopiae star that always appears on captures.

It’s not on the frame but still it's possible feel the strong presence of this big star (at the up-right side of the picture) as a blue light going to the nebula.

Complex nebula to capture (only mag. 10), also with this dominant variable star close who makes so difficult obtain all details and nuances.
