Long Range Reconnaissance Imager (LORRI)

Explanation: LORRI, the 'eagle eyes' of New Horizons, is a panchromatic high-magnification imager, consisting of a telescope with an 8.2-inch (20.8-centimeter) aperture that focuses visible light onto a charge-coupled device (CCD). It is essentially a digital camera with a large telephoto telescope - only fortified to operate in the cold, hostile environs near Pluto.
