Coma Galaxy Cluster (Abell 1656)

This image shows two completely different objects with distances of completely different scales: the Coma Galaxy Cluster in constellation Coma Berenices, mean distance is 321 million light years, and minor planet 679 Pax cruising through our solar system between Mars and Jupiter.
The number of galaxies visible in this shot is amazing: more than 500 objects from the NGC and the PGC catalogues. Swipe to see an annotated version. Practically any marked galaxy ist really visible at least as a small dot. And I could even spot more galaxies which are not listed in these two catalogues.
The Coma Cluster is part of the Coma Supercluster, which also contains the Leo Cluster (Abell 1367). It is the closest massive structure to our own supercluster, the Virgo Supercluster.
Accidentally small minor planet 679 Pax photobombed this image and travelled slowly next to star TYC1995-1936-1 or HD112734, the blue (double) star to the top left. Swipe to see the trace next to the bright star and a short movie showing the movement over the acquisition time of about 4.5 hours. The small planet has a diameter of about 60 km and it orbits the sun with a period of 4.16 years … somewhere between Mars and Jupiter. Pax is named after a Roman goddess, but is is also the Latin word for „Peace“ … what a coincidence in these times.
The image is mirrored compared to the „normal“ orientation, because it was acquired with a RASA … and I forgot to flip it … 😉
