I posted the following article to net.rec.photo, and somebody
suggested posting it net.astro as well.  Since this is net.astro, I
suppose it would be nice to know when an opportune time for
photography would be --- am I already too late?  I know I have to
avoid city lights and a full moon...  (I'm located near Toronto (east
of Detroit)).

As the Halley's comet is around, and I probably won't be the next time
it is ( :-), I'd like to shoot some pictures.  But, but, but, I have
really no idea as to how to go about this.  Just taking random
pictures with random lenses, film and exposure doesn't seem like a
good idea.

So, what kind of film should I use (I'd prefer slides, but...)?
What about exposure times and apertures?  The lenses I either own or
can borrow include a Canon 100-300/5.6, Tamron 70-200/3.5 and a
Vivitar 75-205/3.8.  I also can use a Vivitar 3x multiplier and a
Makinon (el cheapo) 2x multiplier.  What kind of combination should I
be using to avoid huge grain and massive lack of sharpness?

Thanks for any help.
