NOTES:
--------
(1) Getting more familiar with the limitations of observing from the
     bedroom of my apartment on 4th floor through the glass of my large
     window. Due to local light pollution I can only see naked eye down
     to about mag +2. With the 8 inch reflector and stars trailing the
     stellar limit appears to be around magnitude +10.8. Since the
     telescope is stationary the geosats "integrate" so I can get down to
     about magnitude +12.5 on these objects, so the main problem I have
     at the moment is sometimes not enough field stars for the automatic
     astrometry done by APEX so I am now measuring some images manually
     so not as accurate as APEX provides. Reported magnitudes may not be
     too meaningful as sometimes window horizontal frames are in the
     field of view so background sky level may not be uniform and of
     course sky background depends on where observing - eg at 11 degrees
     elevation the lights of Cape Town are objectionable.

(2) I still think I can make some more improvements but will require
     some experimentation :-))

Cheers
Greg
