On the Way to Pluto: Neptune's on sight!

Caption NASA:"The New Horizons Long Range Reconnaissance Imager (LORRI) observed Neptune on June 23, 2010, as part of a test of the critical Optical Navigation Annual Checkout (ACO).
In this 100-millisecond exposure, taken when the Spacecraft was 23,2 Astronomical Units (about 2,15 Billion Miles) from Neptune, the Planet appears slightly larger than a star. At the time of this observation, the Solar Phase Angle was 34° and the Solar Elongation Angle (Planet-Spacecraft-Sun) was 95°.
Only New Horizons can observe Neptune at such large Solar Phase Angles, which can be used to study the light-scattering properties of Neptune's Atmosphere".
