[APML] hypering and blank film

[Alan Jones <ajonesmis@yahoo.com>]

Question for you hypering experts:  Is there something
you can do while hypering that would cause the film to
not record anything?  I've just gotten my first roll
of hypered LE400 back and it's completely blank except
for a single regular light exposure at the begin and
end that I use to align frames (so I know it was wound
properly in the camera).  I shot M45 exposures (LX200
@ f7) from 20min to 45min.  I got back zippo!  Not
even a hint of a star (and yes, the cover was off the
scope!).  Anybody have an idea?

Thanks,
Alan
