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.
Gamma Cassiopeiae is a star at the center of the distinctive “W” asterism in the northern circumpolar constellation of Cassiopeia. Although it is a fairly bright star with an apparent visual magnitude that varies from 1.6 to 3.0.
Gamma Cassiopeiae is a Be star, a variable star, and a binary star system. Based upon parallax measurements made by the Hipparcos satellite, it is located at a distance of roughly 550 light-years from Earth. (star description credits: Wikipedia)
