Markarians chain

Springtime is galaxy time. At this time of the year, the constellations of Virgo and Coma Berenices are high in the sky. And in them, a myriad og galaxies. The below image is an approximately 3 hour integration of the Markarian Chain. A chain of galaxies strung out across a small piece of the sky. If you click on the image to see it full size, you can make a myriad of smaller, faiter background galaxies. This area is littered with galaxies. But most of them need a bit of exposure to be revealed.
