REMARKS:
-------------
(1) An experimental run using an old MINTRON video camera.
Images captured at 30 fps, with exposures of 0.96 seconds.Using
the program Virtual dub I did a screen capture when the satellite
moved. This image was then submitted via AstromImageJ to
nova.astrometry.net and coordinates of leading satellite edge read.
The PC clock was controlled by an external GPS unit which updated the
computer time every minute. This time was time stamped in each
video frame and when going through Virtual Dub I stepped a frame
at a time.

(2) Whilst this method works - at least appears to do so - the
video image quality is not that great, being rather noisy.
Despite the large number of "hot" pixels nova.astrometry.net
had no problems solving each image.

Cheers
Greg
