Description

Markarian's Chain is a field of galaxies in the Virgo Galaxy Cluster. In addition, there are a huge amount of background galaxies visible, the furthest being the Quasar RMB 98 with a redshift of about 1.8 (south is down here). Unfortunately I had problems with the acquisition computer that night, so only about 1 hour of the images were usable. I still think it is quite a deep image for the short integration time.
