Observations 11 FEB 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.

cloud. Eventually gave up. Seeing quite good for Cape Town but transparency poor.Sensitivity of ccd camera is definately down on such warm nights ( ~ 20 to 23 deg C). (2) Last time this season for USA 129 - got it just as it peaked above local roof tops before going into shadow. Still have a few more days with USA 186 before I loose it for this season. (3) Looks like MENTOR-2 #25336 still drifting slowly westward.
