Observations 21 Nov 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. 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.) Used with 135mm focal length f/2.5 lens,Field of view 2.4 x 1.8 degrees. Individual frames are video time stamped with GPS derived signal. Images processed and measured manually.
