Observations 18 Oct 2009- Part 2 ------------------------------------- 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 and the MINTRON used for leo objects that require a time resolution of at least 0.1 second. (1)~100mm 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 3.3 x 2.6 degrees and showing about mag +12 stars in "real time". Used as a finder for the 4 inch refractor. Individual frames are video time stamped with GPS derived signal.

(2) The remaining observations done with the 4 inch refractor and processed with APEX will be posted shortly then I think I am up-to- date as I want to do a short observing spell tonight for some objects of interest.
