Observations 16 JUNE 2010 ------------------------------- 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. 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 reducer 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 15th 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.

Fortunately the loss of this oscilloscope will not affect geosats but Ill have to make some other plan for leos.
