This is same as www.gigapan.com/gigapans/116511, except the image has been enhanced with a gamma correction(performed on the floating number pixel brightness, before converted to an RGB image). Gamma=1.2.
With the gamma correction, the brighter end(high density region) is represented with more luminosity dynamic range, revealing more details in structures within major halos and galaxy clusters.
However the trade off is the entire image is getter darker, because most of volume of the universe at this late stage of structure formation(z=1.0) is filled with emptiness, which we call them the cosmic voids.
