NOTES:
--------
(1) General tracking of classified leo sats. Nice night.
(2) Next session will change focal length to about 150mm- this will
increase my field of view to about 7.8 x 5.7 degrees and see how
effective this is when tracking on a satellite as it should
increase the likely hood of observing a satellite somewhat "off
prediction". The downside is of course the reduced image scale
with subsequent reduction in accuracy but probably better to see
a satellite than not see it at all.
Cheers
Greg
