The Clementine Star tracking cameras (STC: A-STAR and B-STAR) used silicon CCD technology with a 384 x 576 pixel array sensitive between 0.4 and 1.1 micrometers. It had a wide field of view, 28 degrees x 43 degrees, to make more stars available for attitude determination. Its instantaneous field of view (IFOV) was 1.3 mrad. STCs were primarily used for spacecraft navigation and orientation. The scientific uses of these cameras are secondary. The line-transfer electronic shuttering limited imaging to dim targets such as the lunar surface illuminated by earthshine. Information about STC products can be found in:
