A quick (20min) test shot of a very rarely photographed but fascinating object i am hoping to visually observe when i visit Chile in a few weeks.

Distant quasar Q2237+030 sits directly behind foreground galaxy PGC 69457 creating four images of the background quasar due to strong gravitational lensing. The quasar itself is 8 billion l.y away while the foreground galaxy a mere stones throw at 400 million l.y. The light captured here from the quasar left its source so long ago that our Solar System had yet to form!
The galaxy nucleus was not detected (greater image scale is needed.) The whole cross spans little more then 2" in angular size.
