Comment : In the constellation Coma Berenices you find a galaxy cluster. This photo is centered the galaxy M64, it also have the name Black Eye Galaxy. The name comes from the dark spot in center of the galaxy. Little bit difficult to see here with this low magnification. The distance to the galaxy is 17 million light years. It's not until the local time is 23:30 it's dark enough for astrophotographing and it ends already at 02:00. Click on the image above to see the details, not so many galaxies as I expected. But with some computer assist from Astrometry.net: M64 plate solved, there they are.
