Description This emission nebula is located in Cassiopeia at a distance of approximately 7,100 light years. The bubble-shape of this nebula is the consequence of stallar winds from a massive young star at its center. The above image is the result of a total of 6 hours of H-Alpha imaging aimed at capturing the H-Alpha emission light of this nebula, and cropped for composition purposes.
