This study investigated ways to obtain high SNR (Signal-to-Noise Ratio) pictures with a HARP camera at very low light intensities. It was confirmed that an intermittent scanning of the HARP tube was the most suitable and effective method, especially for shooting objects in slight motion. NTSC and HDTV HARP cameras which used this technology actually could even shoot faint nebulae and aurora with clear images.
