Site 0435 Pinelands (Cape Town,South Africa)
18.5101 degrees east  33.9368 degrees south altitude 25.5 metres

ZWO ASI 174MM cmos camera with telephoto lens set at about 80mm
focal length and aperture f/2.8. Field of view 7.74 by 4.86 degrees,
1x binning and image scale 14.5 arcsec/pixel.( For leo sats).

Save for one geosat all geosats were done at focal length about 135mm
Still experimenting a bit here. Too long an exposure with resultant
long star trails confuses NOVA.ASTROMETRY.NET and is unable to solve
the image.

Timing provided by Dimension 4 and Network Time Synchronization
(NTP) and better than 0.1 seconds.

NOTES:
-----------
(1) Some confusion as to which is which as close together, namely
    PAN #35815 and YAHSAT 1B #38245. I think I have them correctly
    identified.
(2) NOSS 7(A) was a single flare - correct position and track angle
    so suspect NOSS 7(A).
(3) Several other satellites seen but either IRIDIUMS or garbage
    STARLINK satellites which are a real PAIN !!!!

Cheers
Greg
