In Focus: The Voyage of New Horizons: Jupiter, Pluto, and Beyond

Alan Taylor, writing for In Focus:

A white arrow marks Pluto in this New Horizons Long Range Reconnaissance Imager (LORRI) picture taken on September 21, 2006. Seen at a distance of about 4.2 billion kilometers (2.6 billion miles) from the spacecraft, Pluto is little more than a faint point of light among a dense field of stars. Mission scientists knew they had Pluto in their sights when LORRI detected an unresolved “point” in Pluto's predicted position, moving at the planet's expected motion across the constellation of Sagittarius near the plane of the Milky Way galaxy.

As usual, In Focus is the place to go for anything picture-centric. And New Horizons—incredible. Think of what was accomplished here. Quite a day for the human race.
