Perseus Galaxy Cluster, at the center (October 2016)

Here is the heart of the Perseus Galaxy Cluster.  How many galaxies can you count in this frame?  I count over 30 without really trying.  The scene is dominated by two particularly large galaxies near the center, NGC 1275 on the left and NGC 1272 on the right.  NGC 1275 is a monster both in size and in character.  Here is my take on the Hubble data of NGC 1275.  The chaos you see in the Hubble data actually lies in front of the galaxy, but the galaxy does have an active black hole at its center and is one of the largest galaxies known.  (You can see some of the chaos in my own image if you look closely, by the way.)  The Perseus Cluster is roughly 230 million light years away.  This image is 12x720" with the SXVF-H9 through a CLS filter and the CFF 290 Classical Cassegrain.  The image is not full size but is not far off.  The moon was up in the southwest at the time, about 70% full, and this image was taken from the suburbs.  I would really like to repeat the experience from a dark site.
