This is an experiment, I heard about this object and wondered what would be visible if I tried to image it. So I took 25 Luminance integrations of 600s each, and added 3 x 600s each for G and B, and 6 x 600s for R.

To my surprise, I could even detect the arcs (very faintly) on a single integration. Judge for yourself, almost exactly in the middle of the image there are two very small and faint dark orange galaxies with faint hints of arcs around it. A nice comparison image can be found on the Hubble Space Telescope images website: A smiling lens
My image is rotated 90 degrees clock wise compared to this Hubble image, can you spot the cat's face?

I made a Comparison Image that shows the ESA/Hubble photo on the right.
