Observations 09 MAY 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. 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. Meade DSI Pro II Monochrome CCD camera without filters. using integration times of 05 sec min to 30 seconds maximum depending on brightness of sky in particular area.No image processing done but dark field applied. Used with 102mm aperture f/2.56 refractor ,field of view 84 x 63 arc minutes. Can get to magnitude 13 or so in less than 20 seconds exposure. Exposure time to nearest second inserted into image FITS header from PC clock which is checked against GPS signal. Images processed and automatically reduced using APEX.

Nothing found at original GSAT 2 Spacetrack position so GSAT 2 has moved. (2) PAN observed - taken as most western member of the trio of satellites. (3) Only got about 20 minutes observing before clouded out and then about another 20 minutes when it briefly partially cleared again before abandoned observing. My winter has arrived so dont expect much optical in the next two months or so. (4) Managed to get one position on 90004 - recent radio observations by me a few days earlier had indicated that the satellite was running close to current element set so nice to get optical confirmation.
