Deep Field Image

This illustration shows some of the final images used to determine that the coast was clear for New Horizons' flight through the Pluto system. These images show the difference between two sets of 48 combined 10-second exposures with the Long Range Reconnaissance Imager (LORRI), taken June 26, 2015, from a range of 21.5 million kilometers (approximately 13 million miles) to Pluto. http://photojournal.jpl.nasa.gov/catalog/PIA20293
