Thanks again to the kind people who have offered me advice in pm
and in this post.
It looks like next Fri night (11th Feb) might be the night, either
on the school oval or here (but with less kids!)
If on the school oval I can at least show them Jupiter in the lazy
afternoon sky....that would surprise em

Moon will be about half full, so a nice terminator and lots of craters.
Then swing over to Crux and Alpha Cent, Jewel Box and Acrux.
Finally on to Orion when it is really dark and show em M42 in the 12"
with a 2" eyepiece

Keep it simple and hopefully after 3 or 4 objects they are still awake!
Or something like this...hopefully the weather doesn't let me down.
