Observations 08 FEB 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. 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 variable time up to max of 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". Used as a finder for the 4 inch reflector. Individual frames are video time stamped with GPS derived signal. (2)Meade DSI Pro II Monochrome CCD camera without filters. using integration times of 5 sec min to 25 seconds maximum depending on brightness of sky in particular area.No image processing done, but some done automatically in the auto reduction software Used with 4 inch SKYWATCHER refractor- model 1025 - fitted with home made focal reducur to give an f/2.56 system. Image scale is 6.56 arc sec/pixel and field of view 84.8 x 63.2 arc minutes. Shows 14th magnitude stars in real time with reasonably good conditions. Exposure time to nearest second inserted into image FITS header from PC clock which is automatically checked every minute against GPS signal.

(2) OFEQ 5 - not a good pass- brief gap in buildings at max elevation 16 degrees. Large variation in magnitude from invisible and was starting to brighten as it left my field of view. Doubt if this satellite is operational. (3) SAR LUPE 5 - some variation in magnitude but on a relatively long time scale so probably still operational. (4) ISS seen by accident - quite a large image on the screen. With a shorter exposure should be able to see some detail. (5) Did a plane scan for 80-19D but not seen - start of evening visibility so will try again when better conditions.
