    Would someone try to use Yoshida-san's PIXY(-2) system to automatically
check everything on CCD images?  I don't have a firm idea how effective
PIXY would be for short focal length images, but the software is confirmed
to be very effective for at least for a longer lens.  The software
automatically identifies known variables and other catalog objects, so
the human intervention is minimal.

    Well, since the bird is migratory, they are not here now, too.
They must be now spending a long winter vacation season in the southeast
asia (and I have time to watch stars ;-).
