In this crop from the image (or in the full image if you download the 1.6Mb jpg) you can see SDSS J132940.44+471440.3, indicated on the crop (left)
and on the finder image from the Palomar 48" Schmidt (right). SDSS J132940 is relatively bright galaxy at Mag 20.5 but is quite distant with z =
0.257558 corresponding to a distance of ~3 Gly/920 Mpc and a Look Back Time of ~3.0 Gy (about 22% the age of the universe).
But your mileage may vary depending on which cosmological constants you choose. . .
