On my walk today, I noticed something that looked like a tiny planetarium on a neighbor’s deck.
 
“Is that a planetarium on your deck?” I asked, half kidding.
 
“No,” he replied. “It’s a telescope.”
 
“Really? Like a Celestron?”
 
Smiling, he shook his head. “No, not like a Celestron.”
 
Check out what my neighbor does in his spare time.
