#SkyWatch #Astrophotography The blue star in this image is Gamma Cassiopeia, the bright star in the center of the W shape of the #Cassiopeia constellation. The Ghost of Cassiopeia aka #IC63 is the emission nebula to the left of the star. #IC57 is the blue reflection nebula above the Ghost. Reflection nebula aren't hot enough to generate their own light but instead can be seen only by their reflection of light from nearby stars. #StillLearning
