When work and hobby collide

Tomorrow I begin teaching a unit of work on SPACE!!!
Introductory (double) lesson, split by a lunch break...aiming for lots of 'ooohs' 'aaaahs' and 'wows'.
If some of them come back next week and tell me they looked up at the night sky, I will be happy.
Of course, my lesson resources are loaded with pictures I have taken myself.
I am very excited to teach something that I could talk about all day!
