NOTES:
-------
(1) Due to failure of the Microline 8300 CCD camera on Christmas
     Day I am reduced to using my old Meade DSI Pro II monochrome
     camera until such time that the 8300 can be repaired.

(2) This means using new software and trying to determine the
     behaviour of the camera shutter and its timing accuracy. I
     believe I have now got a timing accuracy of better than
     0.10 seconds relative to GPS time but more tests need to be
     done. Camera latency is between 0.08 and 0.09 seconds.

(3) The above measurements were done using APEX, save for
     satellite #35682 DUBAISAT 1 where I had to measure manually
     due to cloud.

(4) I have still to make a remote focusing system - focus in
     this session could have been a little better.

(5) Satellites were obtained by accident and subsequently
     identified and measured.

Cheers
Greg
