Observations 17 JAN 2011 -------------------------------------- Cosatrak 1 (Computerised satellite Tracking System). Camera mount now carries two systems that can be operated together as two totally different sytems and computers used. Generally the DSI Pro II camera will be used for high altitude slow moving objects. Tests seem to indicate that its sensitivity is comparable to the MINTRON ( possibly better) but as its not possible (?) to time stamp to better than 1 second accuracy the time resolution is not good enough for LEO objects. (1) 145mm focal length f/2.5 lens fitted to MINTRON low light level CCD surveillance camera (0.005 lux typical in non integration mode) and 0.00005 lux in STARLIGHT mode with 128 frame integration. Image integrated for 2.56 seconds but exposure depends on sky background brightness. Field of view 2.5 x 1.9 degrees and showing about mag +12 stars in "real time".
