Cosatrak 1 (Computerised satellite Tracking System).

FLI ML8300M CCD camera with mechanical shutter + Trimble GPS

Used with 102mm aperture f/5 SKYWATCHER refractor, fitted with
home made focal reducer changing telescope focal length to 311mm
and thus an f/3.03 system.

Field of view increased from 123 x 93 arc minutes to 3.29 x 2.48
degrees.

Image scale used 14.206 arc seconds per pixel (4 binning) for leo sats and
7.103 arc sec per pixel (2 binning) for high altitude satellites

All images processed automatically by APEX- seems to have the new
setup even better.

Site 0433 : Longitude 18.51294 deg East, Latitude -33.94058 deg,

NOTES:
-------
(1)The 4 inch refractor is my favourite for tracking satellites but the
    rather narrow field of view and the relatively poor setting of the
    telescope ( about 0.2 deg error ) made tracking of leo satellites a
    bit of a hit or miss affair. However by using the focal reducer - a
    41mm binocular objective, focal length 136.1mm I have been able to
    increase the field of view and still get good quality images. I
    could increase it further but would now start to have problems with
    my too bright city sky. Leo satellites are not a problem - basically
    just use exposures of 0.5 to 1 second, but for geo satellites I like
    to typically use around 10 seconds so that it is easy to distinguish
    between a geo sat and an ordinary star.  I have some "fine tuning" to
    do- at the moment the reducer lens is a bit tilted with respect to
    the telescope optical axis - vignetting in one corner and opposite
    corner a little out of focus which would seem to indicate lens is
    tilted a little.

(2) SARLUPE 2 appears to have done a change as quite a bit off 5 day
     old elements. USA 186 also may have done a small change as running
     over 4 minutes early on current elements.

(3) Rest of satellites where expected. Again had a pointing error in
     early evening of about 2 degrees despite taking extra care with
     the calibration - caused me to miss some satellites I should have
     seen. Not sure where the problem is at present - might be
     slippage somewhere in the elevation drive part as azimuth fine.

(4) IDEFIX ARIANE 42P #27422 is a very pretty rapid flasher.
     Inclination 98.2 deg, P 100.7 mins, height 790 km.

Cheers
Greg
