Bernard,
This is really nice. I’m actually working on this one as well. It is placed well in the scope for these moony nights.
I hadn’t seen that nebulous ball in the center in other images.

Hi,
This is an image of IC 63 and IC 59, also known as the Ghost of Cassiopeia, imaged in SHO narrowband. It is an emission and reflection nebula about 600 light years away in the constellation Cassiopeia. The nebula is being shaped by the nearby variable star Gamma Cassiopeia, which is slowly eroding the nebula. Slightly closer to gamma Cassiopeia, IC 63 is dominated by red H-alpha light emitted as hydrogen atoms ionized by the star's ultraviolet radiation recombine with electrons. Farther from the star, IC 59 shows proportionally less H-alpha emission.
Comments and suggestions appreciated.
