The galaxy near the top of the image is the lensing galaxy for Einstein's Cross. A phenomenon of gravitational lensing. The galaxy lensing galaxy is about 600 million light years away (fartherst object to date). If you pick up the cross, you are seeing a quasar behind the lensing galaxy that is about 8 billion light years away. The conditions were not good enough to detect any lensing. The scope was an 10" f/10.0 SCT using a Canon 20D unmodified. 5-minute expsosure at 1600 iso. I believe this was taken at the Hume Observatory on 08/22/2007. 10" on top of AP1200, unguided.
