Bull’s-eye targeted
On the picture in “Galactic bull’s-eye” (SN: 9/24/11, p. 10), I am quite puzzled. Do my eyes deceive me, or is there another bull’s-eye galaxy behind the first, located at the 1 o’clock position?

How is this possible? Are these strange objects magically clustered along some line pointing towards us?
