To give you an idea of distance, the legend shows 15,000 kms^1? That's about 650 million lightyears. Hubble's Constant is about 75 kms^1/Mpc, so divide 15,000 by 75 to get 200 Mparcecs. A Mparsec is 3.26 million lightyears, so 200 Mparsec=650 million lightyears
The whole image is about 2.6 billion lightyears across. The Observable Universe is considered to be closer to 100 billion lightyears across, so you get a sense of scale compared to the "big picture".
