Claim One:
1. A star camera system, comprising: an optical system configured to focus radiation from a star to be imaged onto a collector disposed at the focal plane of the optical system; and a collector in the form of an electron bombarded active pixel sensor, the collector including: a photocathode disposed in a vacuum and configured to release electrons into the vacuum when exposed to radiation focused thereon by the optical system; an active pixel sensor anode having pixels of a predetermined size disposed distant from the photocathode in the vacuum; and a voltage source to generate an electric field between the photocathode and the active pixel sensor anode configured to direct the electrons from the photocathode to the active pixel sensor anode to generate an image of the star, wherein the collector is mounted on a translation device configured to move the collector relative to the optical system by a predetermined amount of less than pixel size in the focal plane of the optical system, thereby increasing image resolution when a plurality of images taken at different relative positions are compared.
