Observations 14 Jan 2009 ---------------------------- 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)Meade DSI Pro II Monochrome CCD camera without filters. using integration times of 10 sec min to 60 seconds maximum depending on brightness of sky in particular area.No image processing done. Used with 200mm focal length telephoto lens operating at f/2.8. Field of view 1.8 x 1.4 degrees and showing 12th -13th magnitude geosats. Exposure time to nearest second inserted into image FITS header from PC clock which is automatically checked every minute against GPS signal.

(2) Still have the observations made with the video set-up to report. The satellites are: SDS-3F5,USA 189r,90070 and MSX (3) I hope to do some limited observing tonight.
