G'day Peter,
That is a truly GREAT story.
Mind you, you've inadvertantly created a "mini-monster".
How can you expect the young bloke to observe bed time now that he has his OWN SCOPE and can discover the myriad wonders of the universe wheeling above his head?
Everyone knows that "real" astronomers keep all sorts of strange hours.
C'mon Dad, let's see you get out of that one.
Seriously though, that's a beautiful story. You're a lucky Dad and he's a lucky son.
Best wishes to you both!
