     You had better shoot those pictures soon, unless you're planning
a trip south in March/April.  From Toronto Halley will be impractical,
if not impossible, to shoot after it passes the sun.  Further Halley is
moving rapidly into the evening twilight which should be significant by
January 15.  Currently moonlight is a problem.  The second week of 
January (7-12 or so) would probably be a good time for a shooting
marathon.  I'm not an astrophotographer, just an observer, so I'm afraid
I don't know a lot about how these conditions can be factored out 
with different photographic techniques.  Wish there were cheerier 
observing prospects but this just isn't a well placed return for
northern observers.
